How it works

First wind turbine without blades nor gears

// Fundamentals of the idea

Vortex Bladeless is a vortex induced vibration resonant wind generator. It harnesses wind energy from a phenomenon of vorticity called Vortex Shedding. Basically, bladeless technology consists of a cylinder fixed vertically with an elastic rod. The cylinder oscillates on a wind range, which then generates electricity through an alternator system. In other words, it is a wind turbine which is not actually a turbine.


Vortex wind generators are more similar in features and cost-effectiveness over time to solar panels than to regular wind turbines.

Structure & geometry


The outer cylinder is designed to be largely rigid and has the ability to vibrate, remaining anchored to the bottom rod. The top of the cylinder is unconstrained and  has the maximum amplitude of the oscillation. The structure is built using resins reinforced with carbon and/or glass fiber, materials used in conventional wind turbine blades.


The rod’s top supports the mast and it’s bottom is firmly anchored to the ground. It is built of carbon fiber reinforced polymer, which provides a great fatigue resistance and it has a minimal energy leak when oscillating.


Naturally, the design of such wind turbine is quite different from a traditional turbine. Instead of the usual tower, nacelle and blades, our device has only a mast made of lightweight materials over a base. This reduces the usage of raw materials and the need for a deeper foundation.

Energy conversion

Our bladeless wind turbine captures the energy from the wind by a resonance phenomenon produced by an aerodynamic effect called vortex shedding. In fluid mechanics, as the wind passes through a blunt body, the flow is modified and generates a cyclical pattern of vortices. Once the frequency of these forces is close enough to body’s structural frequency, the body starts to oscillate and enters into resonance with the wind. This is also known as Vortex Induced Vibration (VIV).

Vortex Technology, fluid dynamics


This VIV phenomenon is commonly avoided in structural engineering, aeronautics and architecture. Quite the opposite, Vortex’s turbines maximizes this aerodynamic instabilities and wind turbulences, capturing this energy.


Vortex’s mast geometry is specially designed to achieve maximum performance to the average observed wind velocities. It is able to adapt very quickly to wind direction changes and turbulent airflows commonly observed in urban environments.

The disturbance of the downstream wind current is why regular turbines need to be installed far from each other. This doesn’t affect bladeless wind turbines, any limitation associated with the “wake effect” is avoided. Furthermore, we expect Vortex devices to work better together, feedbacking each other if they have the proper free space around them, which is estimated to be half of the total height of the device. For regular wind turbines, this free space is usually five times the total height of the device.

Vortex’s alternator

Currently, Vortex generates electricity through an alternator system, made by coils and magnets, adapted to the vortex dynamics, without gears, shafts or any rotating parts. Our Vortex generator is currently considered a “small wind turbine”.


Alternators are a well known technology, altough the way Vortex is using it is innovative and patented. This design allows to reduce maintenance and eliminates the need for greasing.

Frequency tuning


The frequency of the Vortex shedding is proportional to the windstream’s velocity, however each structure has its own natural vibration frequency. To match wind frequencies with a device’s natural frequency you should modify the body mass (the more mass the less natural frequency) and the rigidity (the more rigidity, higher frequencies), among other parameters. Therefore, you would need complex mechanisms to vary the natural frequency of that device.


To avoid this, Vortex design uses instead a magnetic confinement system with permanent magnets that increase the apparent stiffness of the system according to their degree of flexion. The degree of flexion grows as long the wind intensifies. We call this “tuning system“.


As a result, Vortex’s patented self-synchronization system allows capturing a wider range of wind speeds with no effort, with a cut-in point in 3 m/s approx (start speed). It can automatically vary rigidity and “synchronize ” with the incoming wind speed, in order to stay in resonance without any mechanical or manual interference.  This way the aerogenerator’s lock-in range increases.

// Von Karman Vortex effect

The Vortex Street effect or Vortex Shedding effect was first described and mathematically formalized by Theodore von Kármán, the genius of aeronautics, in 1911. This effect is produced by lateral forces of the wind on an object immersed in a laminar flow. The wind flow generates a cyclical pattern of vortices, which can become an engineering challenge for slender structures, such as towers, masts and chimneys. One of such examples is the collapse of Tacoma Narrow’s bridge in 1940, USA.

``Vortex successfully adapts its natural frequency to resonate with the wind's frequencies within a wide wind speed range``

Understanding the vibration


The idea behind Vortex wind turbine is that it is possible that same forces can be exploited to produce energy. When the wind vortices match the natural frequency of the device’s structure it begins resonating, hence oscillating, so the bladeless wind turbine can harness energy from that movement as a regular generator.

You will find lots of examples of the Vortex Shedding effect in everyday life. Based on this principle, and bearing in mind some other physical phenomena, such as Betz’s law, finite bodies’ aerodynamics, turbulence regions, wind gradient, etc… the Vortex’s team have created lots of computational models which will shed light on the proper geometry and parameters to develop and improve the efficiency of Vortex design.

Computational simulations


Although 2D simulations are very interesting for us, VIV is a 3D phenomenon. Interaction between vortices along the device have been described by other authors. Since ours is a new technology, we have to create new models and confirm their validity. These 3D simulations are based in the Reynolds number, an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations


A big amount of computation resources are needed. We work hard using Altair’s simulation software trying to find the best way to achieve optimum results with an affordable quantity of computation resources and time. We also collaborate with Barcelona Supercomputing Center using their computational and expertise resources.

// Main features

Materials & Life span


Current wind turbine technology need to support very different load levels under variable wind speeds, which puts high mechanical demands on transmitting components such as gears, bearings, bushings or brakes. The multiple moving parts are constantly under wear, which leads to high maintenance costs.


Bladeless wind turbines completely eliminates mechanical elements that can suffer wear by friction. The main materials used for manufacturing Vortex turbines are carbon fiber polymers, plastics, steel, neodymium, and copper. The working limits of these materials are far away from Vortex’s operational standards.

Stress & Fatigue


Of course, this wind turbine is not immune to fatigue and stress forces. Fatigue is defined by the weakening of a material caused due to repeatedly applied loads or forces. Vortex turbine’s rod suffers continuated flexion and a material failure could eventually occur. The first products have been designed paying special attention to this issue.


The carbon fiber rod was designed to work at a maximum oscillation amplitude of 2,7º. This implies a very low material’s deformation. Computational and mathematical analysis carried out in relation to the component most affected by this phenomenon of fatigue make us think that Vortex aerogenerator has a huge life span.



One of the main advantages of Vortex turbines are the low costs associated. We have estimated that Vortex turbines’ levelized cost of energy (LCOE) will be lower, which will allow a faster return on investment. Anyway, further research has to be done on this topic to say with certainity.

levelized cost energy

This makes this tech highly competitive not only against generations of alternative or renewable energy, but even compared to conventional technologies. You can read an study about cost-effectiveness for bladeless turbines here.


These cost reductions come from a clever design and usage of raw materials. There is no need for a nacelle, support mechanisms, and blades, that are usually costly components in the conventional wind generators.


Thanks to be very lightweight and to have the gravity center close to the ground, anchoring or foundation requirements have been reduced significantly compared to regular turbines, easing installation.

``Vortex is associated with NGO's, Universities and top Tech Research Centers worldwide``

Generation capacity

In wind energy conversion, power generation is proportional to the swept area of the wind turbine. Vortex currently sweeps up as much as 30 % of the working area of a conventional 3-blades-based wind turbine of identical height.


As a result, generally speaking we can say Vortex wind power is less power efficient than regular horizontal-axis wind turbines. On the other hand, a smaller swept area allows more bladeless turbines to be installed in the same surface area, compensating the power efficiency with space efficiency in a cheaper way.


The Vortex Tacoma (2,75m) estimated rated power output is 100w once industrialised.

vortex bladeless technology


turbine barVortex devices are always oriented to the wind thanks to the mast circular cross section. Wind turbulences or mixed windstreams does not affect the aerogenerator’s function.

No brakes required

Resonance disappears beyond the lock-in range, so Vortex stops oscillating by itself without the need of brakes if wind speed exceeds the device’s threshold.

Installed power density

power barAny limitation of the “shadow effect” is avoided. Required separation distance between devices is very short since Vortex’s weak has no negative impact on  downstream devices.

Any speed performance

energy barVortex technology is designed to generate energy from very low wind speeds, more frequent in residential or urban emplacements.

Quiet clean energy

wind barVortex has no moving gears and the oscillation happens at very low frequencies so the device functions quietly when properly calibrated. Easy and simple as a solar panel!

Atmospheric adaptation


In urban environments wind airflows are usually very turbulent, this is an issue for regular wind turbines. In addition, the wake of conventional windmills is problematic when installing several wind turbines working together in the same place.


On the other hand, conventional wind turbines need an orientation system to face the incident windstream. Vortex wind generators doesn’t need it anymore due to its circular cross section.


VIV effect is based on fluid turbulences. Consequently, this bladeless wind generator will adapt very quickly to wind direction and intensity changes, no matter the turbulences. A fully developed laminar wind flow is not necessary for a Vortex turbine effective operation.

``Low cost, easy installation and soft maintenance. Plug your Vortex and go!``

// Eco-friendly

Vortex turbines aim to be a “greener” wind alternative. Athough a more rigorous carbon footprint analysis is needed, bladeless wind power seem to bring some extra advantages from the environmental point of view.


Vortex bladeless is mainly a solution for distributed energy generation. It is perfect to be placed near a house or over the roof. It can work on grid and off grid, and as a part of a hybrid solar installation plus wind generation.

Environmental impact


Its simple design and light weight allow a very efficient use of raw materials. No complex manufacturing process is required to build a bladeless wind turbine, although current methods has to be sightly different to industrialise the production. The absence of lubricants makes unnecessary to manage this waste.


The total weight of a Vortex Tacoma is estimated to be less than 15 Kg once industrialised. Unlike regular rotating-based wind power, with the proper calibration and anchoring we expect Vortex technology to be completely noiseless. As an extra, Vortex Bladeless design’s interferences on radio signals are neglegible.


Wildlife’s impact


Although small wind turbines usually do not represent an important issue for local wildlife, bladeless wind power’s impact on birds population is expected to be much smaller. Vortex’s design allows an oscillatory movement on bladeless turbines to be tiny and less aggressive than traditional wind turbines, so it won’t disturb wildlife and allow birds and bats to avoid them easily while flying.


The NGO Birdlife is collaborating with us to measure this impact. Wind energy and birds can share the same wind!

      Faster please. You really should concentrate on the consumer market, and not just for the selfish reason that I would love to put these on my farm. . Getting governments to do anything is slow and laborious, and the power companies that lobby them aren’t really interested in renewable technology as it competes directly with them.. They certainly don’t want to see any consumer products that would allow individuals to reduce their dependence upon them. In the American West there are a large number of people who are 100% off grid and much of the developing world is in the same state, and would be far more ready to adopt such a device to simply power a well pump, or supplement an existing PV array in the winter. Marine applications would also probably be largely without large regulatory hurdles. Once you get large number of consumers adopting the technology , then and only then will governments and their energy partners be interested in doing anything larger than a bragging rights “see how green we are” show project. Perhaps crowd source your first offering and see what kind of demand you can pull directly from consumers ….I think you will be surprised.

        Thanks Est,

        1.- Mass produce, distribute and sell (legally with all regulations) is quite hard and a slow process to be achieved by a small startup like us. By now our max capabilities are testing pilots (free to be visited) and we are planning some public-private projects but those are slow as well.

        2.- It can be mounted on boats or campers to recharge batteries when the vehicle is still. When moving by an engine they should be unmounted.

        3.- Install the medium to small ones is pretty simple and you can do it yourself. The “hardest” part is to get a proper surface for the installation (usually concrete), and be lucky that you have nice winds in that location.

        Think like they are solar panels. The bigger the more energy per unit (squared), the higher winds the more energy per unit (cubed), and you can always install a bunch of them in grid or array and sum up in parallel the production.

      • Vortex Bladeless
        Posted at 12:59h, 12 May Reply

        A stator is a part of an alternator, like the one cars have, it is the “static” part of it, where the rotor is the “dynamic part”. Electricity is generated on the electromagnetic interaction between these two parts. In our case the rotor of our alternator does not rotate, so we call it “oscillator”.

        Materials for all alternators are copper, magnets (usually neodymium) and electric steel. Then you can have aluminium or composites for other parts.

It is made of carbon fiber but best material for a DIY project is balsa wood, surprisingly similar to carbon fiber in weight/strength ratio. Thickness is the lowest possible without compromising structural integrity.

      Is there any comparative information on electricity generation? I am thinking of a domestic scenario. How much electricity would be generated by a vortex bladeless unit as opposed to a domestic wind turbine.positioned in the same location?

      • Vortex Bladeless
        Posted at 13:21h, 08 January Reply

        Dear Dave, as many people ask the same here is a different answer so you understand what means to compare wind turbines: “What is faster, a car or a motorbike?” It just does not depend on how many HP the motor has, but scenario conditions like terrain, path, weather… also hard to measure things like aerodynamics, tire physics… and the pilot is a variable too.

        When comparing two wind devices you have to mind that different models behave differently and are built for different ideal scenarios. So the answer to your question is: it can generate twice the energy, half the energy, the same, it really depends on many variables.

        Usually, wind manufacturers give you the Peak Power, which is usually not achieved by any small wind turbine in a regular scenario, so the 1kW turbine you buy can be giving you an average of 100Wh in your domestic installation. For example, for a Tacoma unit of 2,75m high Peak could be around 120-130Wh, but nominal keeps around 90-100Wh, that is very different behaviour than a regular wind turbine, so in a year sum up one could be generating more than the other regardless their peak power because the specific variables of your scenario and the two models compared.

        To sum up, if you know all the variables of the scenario you can try to grasp a number based on the power curves (if they are delivered), but that number will be always wrong. The only way to know this is by installing two turbines and carefully measuring everything for a year.

        Yes, the same phenomena will happen but the difference in density really plays a major role, the Reynolds number can be so high that it may not be feasible for small to medium scale devices. We have really no clue, our investigation is only focused on air, but I think there is a project studying this for water devices, cannot recall the name though. Our patents only cover wind devices so anyone is free to investigate this, it will be nice.

        Posted at 11:48h, 06 October Reply

        Hi, to know how much production you can expect for a wind turbine you need to know the mean wind speed of your area (average speed of the most common speeds) and ideally a rose map distribution of frequencies. With that, you can calculate the average output of a specific model of turbine in your area with your wind (by a power curve). Then you can multiply that for 24h and 365days, taking into account efficiency losses for how changing your wind is and how each turbine deals with this (VAWT and Vortex don’t mind the direction but HAWT do). The number you get at the end won’t match any year’s production but will be close, usually over, the margin error depends on how accurate your initial data is.

        This can be applied to any wind turbine. At the end, the best way to know how much a wind turbine produces somewhere is just to install one there and take measurements over years because there are a lot of variables in the game.

      • Vortex Bladeless
        Posted at 12:53h, 06 October Reply

        Hi, there is no overload scenario with these devices, if the frequency of the vortexes appearance exceeds the device’s threshold it gets out of sync and stops harnessing energy, it just stops. This may be a pro, since you don’t need for brakes nor safety systems, or it can be a con, since you won’t be able to harness occasional high-speed peaks.

        About survival speed this is more on the materials and size, for a 2,75m high machine is expected around 35 m/s for structural-survival wind speed. It is kind of the same as regular wind turbines of equivalent size.

        Most part of the energy harnesses in the wind is turned into electricity or absorbed by the tuning system to keep the structure in resonance. If the base is well fixed and rigid no vibrations should be transmitted there, and if they do, they won’t be able to be absorbed by the base because of the huge differences in the natural resonance frequencies.

        Usually, wind turbines you can find on the market generate in AC. They all include conversion and rectification electronics since the signal generated is also quite irregular and dirty, so it needs to be processed before use. Then they usually output 12V or 24V DC. So do we with Vortex. Power conversion electronics are well known and cheap, and you can reach high efficiencies. Later you can store that DC current on a regular deep-cycle battery.

        In fact you should be able to use the same battery charging electronics and the same batteries as a regular home PV Solar installation.

        Our investigation differs in the previous knowledge about vortex shedding in two main aspects:
        – We want to maximize it, take it to its top, not to avoid it because it make structures collapse.
        – Ours is not a static solid to fluid interaction like in buildings, but the solid is free to move and be an active part of the system. This complicates the phenomenon a lot.

      Have you considered clustering/nesting? It seems that by clustering columns, one would achieve resonance of the whole cluster to amplify the energy produced by each individual column. If one stacked/nested a cluster as a component of another cluster, the energy would be amplified…a “bush” of columns with the trunk column achieving the greatest energy production.

        Close wind devices affect each other as they individually interact with the flow. In regular wind turbines this is called “the wake effect” or “the wake of the turbine” and the efficiency losses of downstream turbines are very noticeable with this. That is why you see wind turbines very far apart from each other and why any “nesting” on wind devices is hard to achieve.

        Our tech is different and we can be more densely packed as our interferences between devices are not so destructive. This is a part we haven’t studied deeply yet but there is some kind of spontaneous synchronization between very close devices, because of the vortexes’ frequencies they left behind. This is not really positive as there is an efficiency loss, but with some distance (half of the device’s height) is barely noticeable. A clustering of vortex devices is indeed possible but you have to mind this wake effect, and mind that the anchoring must be rigid and stiff, it cannot vibrate with the whole system.

      A problem with wind turbines (and water turbines) is abrasion/pitting at the leading edge, requiring blade repair/replacement. Does vortexbladeless have this problem (and if not, why not advertise it as a feature)?

        We were aware that regular wind turbines need quite a lot of maintenance, on the blades, on the gearbox… I didn’t hear about that specific one, it is good to know.

        We have a circular section and the direction of oscillation is independent of the physical orientation of the device. This means we will suffer from abrasion on the whole surface but not always on the same spot, so the real damage will depend on how localized that abrasion is (how regular is the wind), and it might be none. We have a clear advantage and is that a different coating on the mast may solve any problem related to wind abrasion quite easily.

        It depends on the size and what range of wind speed you calibrate it for. There is a nice amount of energy on 15.64 m/s, a 12-15 meters high Vortex device may take quite a lot energy from that.

      The design could easily be integrated into a round enclosure with an interior shaped like a venturi to increase the velocity and power of the wind flowing over it.
      The enclosure would have to rotate to remain aligned with the wind, but this could be done passively.
      Also, you would not have to look at these things wiggling except from directly upwind or downwind. Its creepy.

      Helical windings on towers and chimneys are used to prevent resonant frequency destroying the structure. Which it seems is exactly what you guys are trying to harness. Does your tuning system prevent the resonant frequency occurring?

      • Vortex Bladeless
        Posted at 14:46h, 07 April Reply

        The opposite, we look to enhance this phenomenon to harness its energy. That resonance you mention occurs when the frequency of the turbulencies (vortexes) and the natural oscillation frequency of the structure are close. Our tuning system precisely modifies this natural frequency on the device’s structure for it to keep in sync with a wide range of wind frequencies and velocities. We want that resonance to be harnessing as much energy as possible and for the longest time possible.

      Hi! Do you think something similar on a smaller scale would work to replace road barriers, help power construction projects, and maybe be used in more permanent spaces like parking garages and train stations? Would it be able to generate enough electricity from the ground vibration of moving vehicles as well as wind? I’m thinking places like hospital parking garages, casinos, and airports could possibly be good places to harvest energy from. It would be awesome if they could be easily transported and set up to replace the use of some generators used in construction and for outdoor events.

        Parkings, train stations, airports, highways… can be very interesting places if they are outdoors and have nice winds. Small wind power don’t fill these spots because of maintenance issues and risk issues, which we could solve. About the vibration of the ground to get energy, forget it with our tech. We don’t really vibrate but oscillate by differences of pressure created by wind vortexes.

        Depends on the model, for marine applications that use small devices maybe plastics would be used. The problem you have with salt on regular windmills is corrosion of the gearbox and salt accumulation on the blades and shaft. We may encounter salt accumulation over the mast but that won’t affect the device too much, in general they can be interesting for marine applications and many people has told us. We haven’t tested any though, and they may require some adaptations in the materials anyways.

We are right now partnering with Equinor and others to explore the possibility of these giants.

      I was just curious, if you ever considered a design of short light weight vortex turbines on a a semi trailer. I’m thinking for the purpose of powering a cooler on a reefer trailer rather than using a fossil fuel to power the cooler. Seems to me that a truck in motion would be able to have a steady wind source to power the cooler and extra power stored in a battery system. Have you explored that avenue at all? With the number of reefer trailers on the highway today, that could be a great impact on reducing fuel used just for that application on a world scale.

        Sorry, wind turbines over moving things won’t provide more energy than the one they are making you spend. The second law of thermodynamics here. If your semi trailer is parked and it is windy, you can definitely anchor a bunch on the roof and charge some batteries. But not while driving, it won’t work.

      Hi just a thought, would it be possible to use in a vehicle, to charge or supply power to a motor, I was thinking a about a fan to turn an alternator, to charge or power a motor, But I feel this would also create to much drag, your design would not have this drag, if 2 or 4 were fitted to the front of the vehicle where the radiator would be on a petrol or diesel vehicle. This would increase distant between charges or eliminate then so a self powered vehicle?

        Because of damn second law of thermodynamics that is not a very efficient idea, with our technology or any other wind turbine. Basically that drag, it doesn’t matter how much, will “suck up” more energy than the one that the turbine is able to generate.

        Hi, the charging factor applies to batteries, not to generators. Carbon footprint involves the whole lifecycle of a device from raw material to wasteland. We haven’t set up a production line yet and installed several devices for years to know this. However quick maths involving the amount of materials and production processes tend to say we could have a lower carbon footprint compared to a regular wind turbine of the same height. This is completely uncertain yet though.

      Have you tried combining them as a closely spaced array which might improve the low wind speed resonance by effectively increasing the wind speed between adjacent rods using the bernouilli effect, which your vortex itself uses..

      Or perhaps have variable inlet vanes that create a bernoulli effect at low wind speeds, these could turn to face the wind direction and angled to open wider apart as the wind speed increased to reduce the effect. They could be aligned to face the wind by a tail and the opening angles could be set by a tail operating against a spring.

      These changes/additions might allow operation from a much lower speed wind range, giving more useful output and a greater operational location potential.

      • Vortex Bladeless
        Posted at 20:52h, 12 April Reply

        That is very interesting thinking. There is somehow a synchronization between nearby devices that comes from differences in pressures created by several devices as a system itself, we don’t really understand yet why very close devices behave this way though. However, there can be more harnessing of energy than the potential amount contained in that specific conditions, and on low wind speeds way less energy is contained. Although a bernouilli effect may provide higher effective flows, the wind potential remains the same… or at least I think so. There is a lot left to investigate with this tech.

        I think you may be over complicating the idea. And also mind that no wind turbine makes sense when your vehicle is moving by an engine, they will make you waste energy. When you are parked wind power can be a nice option to recharge your batteries, but that requires a different installation than the one you mention.

        Posted at 13:49h, 18 March Reply

        That depends on the PVP, the installation costs and the sum of maintenance costs.

        If you think about small wind turbines, like 2m diameter or so… as an example, one that provides 300W nominal at 12 m/s costs 800€ installation included. It has around 15 years lifespan, in which you will spend around other 800€ in regular oiling, maintenance from the seller and a spare blade and gearbox once. If you have a mean wind speed of 6 m/s (and that is quite high) your turbine will provide you around 100 W/h average, that is around 870kWh/year and we are supposing very good constant winds. In Spain kWh costs around 0,17€, that is a profit of 150€ per year without counting losses and energy leaks.

        If you look at the real ROI of small wind turbines you will see they don’t worth it unless you need them. With big and huge wind turbines this ROI can be better, but PV solar still wins here.

        Same experiment as above but with a Vortex Tacoma will provide you a bit less energy and revenue, but you will spend around 400€ on the tacoma and installation, and around 200€ on its maintenance and a spare mast once, in 15 years. So which one may have better ROI in this case?

        HOWEVER! The data provided here is not based on real experiments so don’t take the figures as true. It is just a mind exercise to understand why there are no small wind turbines in houses, urban network or rural places, and we see PV solar instead. We may be able to change that!

        The slow oscillation of big vessels or skyscrapers won’t affect the operation of medium to small devices. There is no way for our devices to take advantage of those oscillations. They can be generating power from the wind since rooftops are very windy, the higher the more wind usually.

        Sure, the output depends on the size of the device and, of course, the wind conditions. This happens the same for regular wind turbines.

However, the bigger the device, the more cost-effective either the production and the operation, so our mind is on Vortex Tacoma, a bigger device which will produce much more and will cost a little more.

        Well as we don’t have a production line nor a fixed design we don’t have those data, sorry! our devices are in development.

        However, as an estimation, we can tell you that compared to a regular HAWT of the same size (from ground to the top of the blade) we would use kind of same materials and in some ways we are similar but:
        – We need 30% less steel per W produced.
        – We need 10% more fiberglass per W produced
        – We need 10% more copper per W produced
        – We need 20% more neodimium per W produced
        – We need 60% less process and workload on production
        – We need 90% less maintenance costs per W produced
        – We need 30% less surface to operate properly (therefore less land costs)
        – We need 70% less ground foundation
        – We produce 0% waste from oils in our lifespan (no oil is needed in fact)
        – We expect our LCoE (levelized cost of energy) to be 30% less, therefore the carbon footprint should be around 30% less or so.

        Take this as very vague estimations as size matters a lot in cost-effectiveness over time for devices of 20 years lifespan. We haven’t built devices as big as regular wind and we haven’t an industrial production and haven’t tested a device for its whole lifespan yet.

      Dear, I am working on a project in the arctic, looking for a low power (50W, or 100W like the Tacoma) wind mill for an automated weather station. Do you think your product could work in arctic conditions (-40C, occasional high wind 150 km/h)?

      • Vortex Bladeless
        Posted at 13:08h, 03 December Reply

        Dear Pierre, 40m/s (150kmh) is in the limit line for survival conditions of Tacoma, but if you are aware of those strong winds with enough time you can always protect or even deinstall the turbines (it is pretty easy). -40C is not a problem in principle, but we haven’t performed trials on such temperatures yet. Snow accumulation is not a problem due to its shape.

        The main issue I see here may be ice condensation over the mast, which will change the weight ratio and may change the centre of gravity. This won’t break or stop the device, but it won’t perform correctly. However, this can be fought by the same way as regular wind turbines do, by heating up the inner of the device with part of the power generated. In our case, this heating could be more efficient since we have less volume to heat up.

      Hey so I’m just confused as to how horizontal oscillating transfers into the rotation that a Alternator uses to generate an electric field? Or does it use another form of alternator to turn its motion into energy?

      • Vortex Bladeless
        Posted at 13:37h, 03 December Reply

        Hi! The point is that there is no rotation, no gears or shafts at all. An alternator generates electricity by the electromagnetic induction that happens between copper and magnets, this happens by rotating the rotor over the stator in regular alternators. In our case this movement is semi-spheric, we have an “oscillator” instead of a rotor, and a stator. This electromagnetic induction happens the same in our system, although we are far from the level of optimization that current rotatory alternators have (obviously). Most of our patents refer to this alternator and tuning system, and it is the most complicated piece of engineering we have. Our first years were dedicated to get a design and a geometry that harness as much energy as possible from the wind, and then we focused on this alternator. We currently have some promising models over the table that are being tested in pilots with Vortex Nano devices.

      What’s the smallest but still effective size for this?
      I mean, could this be an addition for example to rooftop solar panels, by installing one of your devices in the gaps between said solar panels and chain them together, to ha more energy even on cloudy/winter days? Also: would it be effective on a saddle roof or does it need to be perfectly aligned to be vertical?


      • Vortex Bladeless
        Posted at 14:04h, 03 December Reply

        Power generated grows exponentially with size, squared to height and cubed to wind speed. Size is also a factor for the wind range it will work better, so very small devices will generate a small amount of energy, and huge devices will be very cost-efficient. Smallest effective size? It depends on what do you want for that installation. But yeah you could install Vortex Nano devices between solar panels and chain them together if their shadows don’t cast over panels.

        They should be completely vertical although they could work not being completely vertical, but won’t perform OK.

      I am an engineering student and I find your idea really impressive. But I cannot find any calculations based on wind velocity and other factors that show vortex wind turbines producing the aforementioned power. I would like that information for my project on bladeless wind turbines.

        P= 0.5*1.225*A*Cp*0.95*(V^3)

        where, P is power output (Wh). A is swept area (m2). Cp is Coefficient of performance (0-0.5). V is wind velocity (m/s).
        A on Tacoma models: 1.7 m2 by now (approximation, and it is really a 3d curved surface)
        Cp on Tacoma models: still under development, we think we can reach around 0.3-0.35 with proper trials and optimization (kind of same as VAWTs). Maybe more on really big devices, this is still state of the art. Maybe the same Cp of current big wind turbines can be achieved on big vortex devices. Time will tell.

        If you are calculating this for a regular wind turbine take into account losses for the gearbox performance, we don’t need for one. Cp on small wind turbines is lower than in bigger ones. A very nice HAWT of around 4m diameter can reach 0.4 Cp max. or so, higher is hard for smaller turbines than that.

        Don’t know the number but you can calculate it. Oscillation angle at full operation is around 2,7 degrees on each side, the oscillation frequency is around 11Hz for a 2,75m high one. The free part of the mast is virtually 95% of the device height, the alternator is roughly in the middle.

        Hi! the power range depends on the size of the device and on the wind conditions, we are now into testing small scale models with small outputs but which are easier to produce, deliver, install and monitor. We will scale up the trials with time. About your questions, the oscillation of a 30m high device will have around 3 degrees angle for each side and less than 6Hz of frequency. Of course, this oscillation is absorbed and cushioned by the alternator system to be converted into electricity. No vibrations will reach the base that could be transmitted to the foundation or the surroundings. In fact, with these tall devices, you won’t call it vibration since it is so slow it makes no sense, you would call it oscillation, like a boat on the sea.

      How would something like your smallest unit perform on something like a boat? I am thinking of sailboats which are often anchored without shore power but also where there is not enough space for big spinning blades because of masts, booms and stays. Would the motion of the boat due to wave action help generate energy or throw off the harmonic oscillation of the device and decrease output?

      • Vortex Bladeless
        Posted at 19:08h, 01 July Reply

        The wave action on the boat can’t be used in that way. A device on the top of a boat will behave kind of as it was on land. The changes in the center of mass of the boat due to waves can affect its performance negatively but we think it will be ok, this is tiny. Boats are a potential application for our devices due to low maintenance, but power density may not be so interesting in this case.

        Well this ACTUALLY happens on any structure that meets the conditions of frequency resonance with the wind. Remember Tacoma Narrows’s bridge! The point here is that this phenomena is usually avoided because it can make structures and airships to collapse. The point here is to prepare a thing that can take advantage of the phenomenon, amplify it, and then somehow turn this kinetic energy into electricity.

        Although we can work with turbulent winds, a laminar flow is always desired. The answer is that it depends a lot on the topography or what is around the wind turbine. We are working by now with 2 prototypes, 0.85m high and 2.75m high. There are projections and simulations of higher devices and they are desirable in cost/effectiveness, but harder to prototype, step by step

A very small device could work with less than 1 or 2 m/s but will be producing 0,x W.

      You mentioned that a farm of vortex generators might engage in “feedbacking” with each other. I assume you mean that their vibrations will synchronize. Could such a feedback mechanism lead to catastrophic failure like Tacoma Narrows bridge mentioned at the top of this page?

      Or perhaps the geometry of the farm could lead to a situation where the first nine generators are fine, but after adding the 10th generator they begin to shake apart when the wind blows with a specific speed / direction.

        Well, this is very uncertain since simulations over a single device take thousands of processing cores and months of simulation. So it is impossible right now for modern computers to simulate the complete fluid dynamics interactions between a bunch of Vortex devices with enough certainty.

        From experimental trials we have noticed they don’t disturb each other, and in some cases, they seem to help each other keep tuned with the wind frequency better. Unlike regular wind turbines that disturb the wind flow downwards the device, in our case, when the vortexes created downwards catch the next device, it seems to be the same good wind as the laminar wind flow that is getting the first device in line. However, further trials are needed.

        A device needs aprox an area of half of its height radius of free space around. The formula will be A=Pi*(height/2)^2 this give us 1,3m of free space in any direction from the center point of a 2,75m high device. Or 40cm free in any direction from a 85cm high one.

I’m not quite sure how recyclable carbon fiber is, by now we know we will have a lower carbon footprint than regular windmills since we use far less material for a turbine of the same height, and because we need much less foundation than regular windmills, making the environmental cost of installation and posterior retirement much cheaper and less invasive.

        However, we are still under development and this kind of device are expected to have a lifespan of around 20 years (similar to regular windmills). So recycling is not a bigger concern than production to us at the moment.

      Thank you for the recent 2019 update. Your website is very comprehensive and a nice readable layout.
      I look forward to your initial commercialisation of the Vortex concept and hope it will be available for
      installation in North America in the near future.

      I would be keen to plant a few in my area and perhaps become an investor and supporter of what seems
      like an excellent affordable green energy solution for just about any location.

      Merry Christmas 2019

      Merci pour la récente mise à jour 2019. Votre site Web est très complet et d’une présentation agréable et lisible.
      J’attends avec impatience votre commercialisation initiale du concept Vortex et j’espère qu’il sera disponible pour
      installation en Amérique du Nord dans un avenir proche.

      Je voudrais en planter quelques-uns dans ma région et peut-être devenir un investisseur et un partisan de ce qui semble
      comme une excellente solution d’énergie verte abordable pour à peu près n’importe quel endroit.

      Joyeux Noël 2019

      • Vortex Bladeless
        Posted at 12:41h, 08 January Reply

        The rod is connected to the mast by a circular piece we call “ribs”. The alternator consists of two parts, one fixed, one moving, as any other alternator. The fixed part is attached to the inner steel tube which goes from the ground to the middle of the mast. Then the other part of the alternator is fixed to the mast itself.

        We have tried carbon fiber and fiberglass with filament winding techniques with nice results. But on day by day life for prototypes, we use balsa wood (believe it or not it is close to carbon fiber in resistance/weight ratio). However, we think the best material would be graphene.

        Yes, our plans are for the end-user market. It will take time to reach Canada but indeed we will in the future. Power generation depends on the size and on the wind conditions of your area (same as with any other wind turbine). Depending on your consumption and your installation you will be able to reduce the bills or fully power the house, it depends on your variables.

        No, it is based on Vortex Induced Vibrations, it oscillates moved by the Vortexes of Von Karman created by the wind that passes around our slender geometry. If it is properly calculated, vortexes appear synchronized and alternating sides. It happens naturally in real life with poles, flags, chimmeneys, etc…

        Hahaha the Schumann Resonance is an interesting concept but it has nothing to do with us! That is electromagnetism frequency, here we work with aeroelasticity and movement frequency!

        Our oscillation frequency depends on the frequency of the vortexes appearing behind our structure. They appear alongside the mast all at once in each side each time, pushing the mast and making it oscillate. The larger the mast is, the slower the oscillation, and backwards. Also the more wind speed, the more frequency, and backwards.

        I am final year engineering student and I want to answer this question.
        As there are wide variety of frequency, this too is one among them, In aerodynamics we have something called vorticity where fluid seems to rotate about its own axis. whenever a flow past a rigid body it is likely that vortix are formed at the edge, but if the separation (diameter) of the body is wide then we could see that vortix formed at the upper and lower portion are not synchronized and hence there is a time gape as well as spacing. So the time difference between the two adjacent (upper or lower) vortix is what here mean as frequency.
        mathemitically, for cylinder we can roughly estimate by the formula as:- St=(f*D)/u: St is some constant, f-frequency of the vortex , d-diameter and u-free stream velocity.

        If I am wrong then please let me know.

      Hi! I am making my final year project which is vortex bladeless wind turnine. The height of the mast is about 2m but it is generating only 1 W power on a normal wind speed 3-10 m/s. Can you guide me to increase its power?

      • Vortex Bladeless
        Posted at 16:04h, 25 June Reply

        Dear Jabbar, did you build a working prototype? That is impressive! Well, the power generation is delicate, we use a lot of CFD and FEMM simulations (finite element method magnetics) to get an idea of which geometry and design of the alternator work better. However from the computer to real life, there is a gap, and unprecision on the construction or other variables will impact heavily on your power production. We are still optimizing this alternator, it is being the hardest part of the whole development.

        What I see with your prototype is that maybe you are lacking what we call the “tuning system”. It is able to change the apparent elasticity constant of the mast for it to be synchronized with the vortexes in a wider wind range. This way you get a power curve that can be optimized either by working on the alternator’s design and on how the whole system interacts with the fluid on different wind speeds.

        Wish you luck with this!

        Dear friend, I’m afraid that Korea is a little far for a demonstration at the stage we are now. About big Vortex devices (like Grand), they are still on our business plan and roadmap, but this is R&D of a brand new technology so it will take a while to get from small devices to bigger ones. The best way to prove the feasibility of our tech is to grow step by step. Next year we would like to launch a first series of small devices for the people to test them and get feedback so we can keep optimizing bigger devices. We can be in touch for then.

      you have one single mention on this webpage that the vortex is expected to be noiseless, has this been tested & verified on a prototype? I find it hard to believe that a machine that harnesses vibrational kinetic energy wouldn’t make any noise pollution.

      Noise pollution caused by a vortex farm would be an important factor in picking out a facility location near population centers.

        Posted at 17:32h, 25 June Reply

        We are not able to properly measure the noise on a lab environment (in this case a wind tunnel) since special equipment it is needed to isolate the aerogenerator’s noise from the wind and the vents. This test will be performed by the company in charge of certification of our devices before their commercialization (it is compulsory to be certified for wind power in Europe). However I can tell you that due to its design there shouldn’t be any noise, the oscillation frequencies are from 5 to 15Hz, too low to be heard. Also at field tests we haven’t heard any noise coming from the devices.

        It would be like shaking your arm slowly, it is indeed producing noise, it is physics, but too low or too weak to be heard. Same with Vortex devices.

        We are right now working on small devices for small-wind purposes since they are easier to be made, tested and manipulated. The cleverest roadmap for us as a Startup is to scale up the technology step by step, from small technological demonstrators to large scale aerogenerators. About survival conditions, they will be measured by the certifier company before reaching the market since we have not the necessary equipment to test it ourselves. However, computer simulations give around 35 m/s of survival speed for a 2,75m high and 30cm diameter device with current materials. Any changes in the design and materials will change this parameter, so please don’t take it as true.

      Hello Vortex team!
      Congratulations on your invention, as it is fascinating!! I am reading about your new technology to carry out a presentation for school, and I have already read the information in your green paper and your webpage. However, I would really like to know more about how the alternator you are using works (the theory behind it, why it works…). Also, I am not clear as to what happens with the electricity that is generated. Is the wind generator then connected to a general system that can then carry the electricity around to houses…?
      Thank you very much!

        Dear Elena, you can read more about the alternator in our white paper and in the patent registered by David Yáñez. About what happens with the electricity when it is generated, this has no mystery, it passes through a rectifier that stabilizes the current and keeps it at 12V or 24V DC, then it goes out with a cable to a regular inverter and batteries system like the ones for solar panels. In fact, this part is almost the same for any wind turbine since the raw electricity generated cannot be used, it needs to be rectified and stabilized first. This is made with a very simple and well-known electronics, we just buy them.

      “Calculations and trials reveal that most common oscillatory frequency is between 4-10 Hz, which is too low to be heard.”

      Perhaps too low to be heard, but not without detrimental effects on the human brain. I would want to stay at least 10 km away from any wind oscillator.

        The smallest full model we have tested was 80cm high. Theoretically, it is possible to make them smaller and the physics will work, but to scale down an alternator to such small proportions can be quite hard on engineering. Furthermore, with a 15cm high device, you will be generating… idk, like 0,1W? The bigger, the more power produced, exponentially.

      As a practitioner that used energy medicine (frequency, vibration, etc) has there been any studies to determine if the vibrations put out by your unit adversely interacts with the vibrational frequency of humans? Animals? Plants?
      Many people are amazed to learn that if a string on a guitar is plucked in one corner of a room, it will cause the same string on a guitar across the room to vibrate as well.

        Posted at 18:04h, 25 June Reply

        Dear Linda, that guitar string thing you mention is called sympathetic vibration and we are kind of based on that principle to work. In our case, we synchronize the apparent elasticity constant of the mast with the frequency of vortexes that appear behind the structure, this way the mast is able to enter into resonance with the wind vortexes. Same happens on a grand piano where the harmonic frequencies of some strings make other strings to harness energy by sympathetic vibration. Same with an opera singer breaking a glass with her voice.

        However don’t be worry for its effects on humans or animals; for this symphatetic vibration to happen the body harnessing energy should be homogeneous, in other words, a single piece of something like glass, steel, etc… A living thing cannot harness vibrations on this way! Furthermore, on our devices this vibration happens at very very low frequencies, impossible to be heard and also too weak since almost all of the energy is being captured by the alternator and turned into electricity.

        Our devices cannot take advantage of oscillation by the sea on a boat since the interaction should happen between the base and the stator, that are fixed to the ground, and the mast with the “rotor” (in our case oscillator) which interacts freely with the fluid. If the whole system is moving there is no interaction between the coils and the magnets to generate electricity. Nevertheless to install Vortex devices on boats is an idea that we like very much, however, if we want to develop vortex devices for boats we should work on the materials to be sure the harsh environment of the sea doesn’t damage them. By now they are designed for onshore only.

      I admire your caution about not promising too much for the potentially revolutionary future development of your technology, until we see how the elegant engineering solutions scale up.

        Posted at 17:08h, 25 June Reply

        Thanks for your kind words, not everybody understand that R&D of a brand new tech is a very uncertain process.

        About your question, quick answer: a lot. Real answer: that is quite quite complicated to calculate, it depends on the wind resources of that area and the average consumption of that 40k citizens. For you to make your calculations the swept area and power generated grows squared with the height of the mast, and power also grows cubed with wind speed. Bigger devices could use higher winds so if you scale up the technology the power generated grows exponentially. For a 2,75m high device simulations give around 0.1kW at nearly 7-8m/s, for a 12m high device around 1kW at nearly 10-12 m/s.

        If you really wanna get into this, try to calculate the power needs of that city and then with the formula above find the best combination between size, wind speed and the number of devices.

About how much devices well that really depends on your power consumption and the wind resources available in your household. To size up a renewables’ installation is not as easy as it seems.

The main negative aspect of Vortex is that this is a very new and young technology.

        Dear Lauren, the ground has a very different natural oscillation frequency, it simply cannot vibrate the same way as the device does. Moreover, if there are vibrations transmitting to the base, then the device is not working properly! Most of the energy harnessed by the device will be absorbed by the alternator to turn it into electricity, some will dissipate. If the anchoring is correct there won’t be any vibrations on the base!

        With our 2,75m high prototypes, same as happens with solar panels during the night! On any renewables installation at home, you need a battery system and electronics to connect it to your house’s network. In fact, the most efficient installation is a hybrid solar-wind one, if there is no sun there may be wind charging your batteries! However, a small Vortex device (under 1m) would have the power to charge a smartphone or similar, so it is clever if it has batteries inside and a USB out, like a wind-powered power bank.

      How many layers/rows of these devices can be placed next to one another? Visualizing a ‘fence’ made-up of one row you’d place another row behind the first and so one – with each device offset from the ones in-front. I understand each row would reduce the velocity of the wind passing through THAT row while generating added turbulence to benefit the row immediately behind but just how many rows would be practical?

      • Vortex Bladeless
        Posted at 01:12h, 02 February Reply

        Those rows are on different heights? Sincerely we haven’t run any simulations with close devices but at different heights to measure their behavior. But we can tell you that in the same plane, the optimal distance between them seems to keep constant at the half of the total height of the device (around 1,3m radius for a 2,75m high Vortex). They may behave the same at different heights.

        About turbulence, they are not necessarily good, either bad. It is hard even for supercomputers to simulate these fluid dynamics scenarios. But in theory, the best wind would be a constant and laminar one.

        Dear Jordan, there are some aspects that you have to take in mind carefully before building a Vortex turbine for the physical principle of Vortex Shedding to happen: the weight of the mast (as light as possible), the geometry of the mast (this is a hard one), the flexibility of the inner rod (the correct one for the calculated amplitude and weight) and the total length of the device, which has to be with the geometry itself. If some of those aspects are not well calculated the whole device may not work. Mind that even supercomputer models are not able to reproduce the physics of Vortex devices completely, many things of our work has been try and failure, try and failure… fluid dynamics is a really complicated science.

We haven’t taken any grid supply from utility company since year 2010 and have been running our facility using Solar Energy alone. Considering the fact that we had to utilize storage batteries for smooth production process during the day time and night time lighting continuity, we installed a 400W conventional Horizontal Axis Turbine in order to mitigate our battery drains during non-sunny days and rainy season and also to have a diversified energy solution for our day to day needs. Even though the Mounting-Pole is only 10 metres high and the installation is quite professional, the turbine has failed few times primarily due to it’s internal mechanical issues and it’s difficult to repair the same by dismantling the complete assembly. Could you supply us a small unit of say about 80 to 100W generation capacity at wind speed of about 3 to 5 m /Sec. We are ready to be part of the fun of developmental learning.

        Dear friend, wind turbines over mobile objects are useless due to thermodynamic laws. About wind turbines on buildings and skyscrapers, that seems the best option since usually the higher, the better wind conditions. About scalation, power generated grows squared with height (because the swept area grows) and grows cubed with wind speed. Theoretically, a 12m/13m high Vortex device would be able to deliver 1kW nominal (ten times the power of the 2,75m one at similar speeds).

          Interesting, so a 12/13m structure has as similar output capacity as 4m2 of solar PV panels in good sunlight. What about the expected full-load hours?

            That depends on the wind resources but if both were working at maximum, you will get more with a 12m Vortex device than with 4m2 PV solar. However the sun is usually more reliable than wind over the year unless your average weather says the opposite. Therefore usually you will get more energy with PV than with wind power of same output along a year, usually.

      Dear I want to share with you some important element that could be part of your important project;
      Niobium is used with iron and other elements in stainless steel alloys and also in alloys with a variety of nonferrous metals, such as zirconium,

      Niobium alloys are strong and are often used in pipeline construction.

      The metal is used in superalloys for jet engines and heat resistant equipment.

      Niobium is also used for jewelry. At cryogenic temperatures, niobium is a superconductor.

        Dear Friend, that material is pretty interesting, I will forward your comments to our team of engineers. However I can tell you we use a very low amount of metal in our design. Only some parts of the alternator are made of steel and copper, while the main elements are made by carbon fiber and plastic composites.

        Of course a wind power plant can be built using Vortex devices, in this way they would be like any other aerogenerator. But the current size of our wind turbines is not the most suitable and effective for a wind park, but for self-consumption or systems off the grid instead. In the future we want to keep developing and maybe build bigger Vortex devices closer in characteristics to the big windmills that are used on wind power plants. But now we are focusing in the distributed energy market for small-wind or even micro-wind power.

The main points where efficiency can be improved is on the aerodynamic efficiency or how much energy can be harnessed from the wind.

      Hola, te contesto en castellano. Las simulaciones computacionales y cálculos que hemos hecho sobre las especificaciones de los materiales reflejan una vida útil operativa de varios años, similar a la de los aerogeneradores actuales. De hecho usamos materiales muy parecidos a los normales de la industria eólica, pero al ser nuestro movimiento mucho menos agresivo la fatiga y las fuerzas ejercidas sobre las partes móviles del aparato son pequeñas. Por supuesto la vida útil real tiene que ser medida poniendo a los aerogeneradores a funcionar todo el rato durante mucho tiempo y estudiar su degradación. Esperamos que la certificación que estamos llevando acabo ahora refleje datos más exactos sobre esto. En cuanto a las piezas, teóricamente la pieza que sufre mayor estrés es la varilla de fibra de carbono que forma el núcleo del aparato, y es la que te comento que funcionando normalmente debería durar muchos años. En cuanto al resto de piezas no esperamos una gran degradación por el funcionamiento normal del aerogenerador, pero será la certificación la que nos pueda decir con detalle qué piezas serán más propensas a rotura para que podamos mejorar nuestro diseño.

      • Vortex Bladeless
        Posted at 17:15h, 08 November Reply

        The geometry of the mast is designed to maximize the phenomena of Vortex Shedding along the structure of the device. For the oscillation to happen properly, the vortexes that are created from the interaction of the mast with the wind has to happen all together “pushing” the mast in the same direction. This frequency of vortexes’ creation has to be related to the apparent elasticity of the structure of the device for it to enter into resonance with the wind. This geometry has been calculated using fluid dynamics simulation software.

      Has Vortex evaluated the use of man made wind? Anyone that has experienced the force when a large truck passes by at high speed, knows the power of the wind generated. I believe that harvesting this transportation byproduct would be a very efficient source of wind energy, that is dependable, predictable and not subject to any of the variations imposed by nature. I live in Los Angles where large trucks move cargo day and night, regardless of the weather. A small forest of Vortex Tacoma devices placed along the side of our truck routes should be able to produce a very stable supply of power. At reasonable intervals, the power could be input directly into the local power grid, without the need for very expensive power transportation infrastructure. A small array of wind gauges in various places near a truck route should provide the data necessary to fine tune the Vortex designs to maximize the power generated from this wind source. The very small incremental cost of each additional Tacoma unit would allow utilities to place and expand their power generation exactly where they need it most, according to the budgets available.

        Sure! Of course we have thought about this. There are in fact a few projects developing wind turbines to be used in highways and other infrastructures, mainly vertical axis wind turbines. We believe ours could work the same although it may be not as stable as with regular wind turbines since our oscillation depends on the vortex shedding phenomena that happen around and not because of the wind striking the device itself. More research should be done about this but to harness energy from highways’ activity is not a new idea!

      Since Eric’s post and answer above, 3 month are passed. Could you provide new answers on the same questions where you stand now, and what the expectations are?

        Hi! It would depend on the stability and thickness of that brick wall but I think you may have problems with that, an installator or an architect would know better! But I would say that better anchor it to the ground on that case. About Eric’s questions, I would tell you the same. The company is currently getting the devices certified (we are about to pass first stage), as well as getting the quality marks required for selling in Europe. This is going to take more than usual since there is no law for oscillatory wind machines, they have to create a new regulation just for us. About price and ROI, those cannot be calculated until we are in full manufacture stage and we know for sure the costs of the industrialized product, as well as costs of packaging, distribution, post-purchase services, etc… but we want them to be as affordable as possible so everyone can have one!

        Hi Kara! The basis and the physical principles that work on our aerogenerators are suitable for boats as well. On a medium size boat or bigger, the frequency of oscillation of the boat will be very different from the frequency of oscillation of our wind turbine, thus it will behave the same onshore and offshore. About corrosion, I’m afraid I cannot tell for sure, I think some parts would need isolation or special painting to resist a sea environment, but those would be minor changes 🙂

I just had this idea about its possible use in urban environments. Most streets already have lights that are installed on poles. Could it be possible to add a light on top of the bladeless turbine that would illuminate the street? In this way, two useful functions could be unified in one simple object and energy generation would not take up additional space in the urban environment.

        Dear Juris, that is a nice idea. But I’m afraid that the geometry and weight of the mast of Vortex devices need a very detailed calculation and care. Any changes to the mast would affect the whole behavior of the aerogenerator. Maybe thinking about soft led lights for your Vortex at home… but I don’t think that they could replace lamps in cities. Anyway, lamps that are able to generate electricity is an idea with lots of possibilities!

          I certainly understand a typical street lamp (arm, globe, etc.) would not work. However, it occurred to me that using LED technology and a reflector angle mounted behind a flush lens, thereby not altering the geometry, might be feasible. Granted, there is engineering necessary to maintain strength and balance but it seems a viable idea for some applications in cities and along highways. One potential negative that occurs to me is how the oscillations affect the light being cast. That could be disorienting.

            This is very well thought-out! But I’m afraid that you cannot change the weight ratio of the mast either. For the Vortex shedding phenomena to happen the geometry, weight and rigidity of the device are the most important features. You can always have led lights on the base! The bottom part is not oscillating, thus you can have anything you want there. The power output is on the base too.

      And also about the wind speed range ? I’ve already read that 2-3 m/s is the minimum speed that vortex could work in and produce energy. ِDoesn’t it any limitation about the maximum speed? I mean it won’t get into fatigue and failure in high speeds of wind?

        Dear Elmira, I’m guessing that with Cp you are referring to efficiency under the Betz’s limit; current trials and calculations over prototypes estimate it around a 30%. The certifier company will measure that for us with more accurate methods and instruments than ours.

        The wind speed range or lock-in range of Vortex Tacoma prototypes (2’75m high) is between 3 and 10 m/s aprox. with current geometry and calibration. Over a threshold of around 11-12 m/s the device exits resonance state and stops by itself due to its physical principles. Of course aggressive wind speeds (estimated over 30 m/s) will damage Tacoma models with current materials and specs. But bigger devices can be designed for higher wind ranges in the future.

        As you can read on the “Fatigue” section of this page, the inner carbon fiber rod suffers from fatigue and may break eventually; both mathematical and computational simulations reflect a life span for this piece of several years, similar to solar panels. However we are waiting for the certification’s results to publish accurate data about the final product we will launch and not estimations over the prototypes ???? A datasheet of Vortex Tacoma will be available asap!

      Hi Vortex, I like very much what you folks are doing :). It seems to me that your intentions are clearly honourable in that you desire to make your invention available for use by the domestic energy consumer and at as fair a price as you can as a first priority.

      This is a market segment that even in developed countries such as mine (New Zealand) where consumers are trapped by the large energy producers into buying their product at often usurious rates, and a government that because of vested financial interests those energy producers, provides no meaningful incentives for the end energy consumer to adopt alternative energy technology. Often even the cheapest renewable energy technology is unattainable due to individual financial means and ROI time frames.

      Consider this example a baby boom couple approaching retirement age, with even now very little discretionary spending money. People who soon will be solely dependant on a pension and they want to invest in a renewable energy system now so that energy costs do not impact on their remaining years. Where do they even begin under difficult current economic conditions?

      I’m a retired electrical engineer and member of a ski-club in New Zealand. Our Club has lodges serving all three skifields on Mount Ruapehu, the highest mountain in NZ’s North Island. Two of these lodges are actually on-mountain but in different circumstances: Iwikau lodge is adjacent to the Whakapapa SKifield (a large fully-commercial field) whereas Tukino is on the Tukino Skifield, which is also open to the public but is operated by the three Clubs with lodges on-site. Iwikau is grid-connected but Tukino has always run on diesel gensets, although solar is progressively being added to the mix. Mt Ruapehu lies in a National Park (the world’s second-oldest) and is a World Heritage designated area. Because of location at the edge of the ‘Roaring Forties” there is no shortage of wind! But because of NZ lying in the midst of oceans, the wind is often very moist, which causes “rime ice” formation on structures and machinery of unusual severity. Open windmills are unacceptable to the National Park for many reasons – appearance, sound, wildlife and propensity to fling lumps of rime-ice. We are aware of the “Vortexion” device which avoids some of these issues but is likely to be affected by rime-ice interfering with its operation. From what I’ve read so far, your Vortex-shedding device seems to offer operation under rime-icing conditions? We would need any such device to survive structurally at up to 60 m/sec wind with useful operation up to about 25 m/sec. For more general info about Tukino please see Regards GaryH

        Hello Gary, such a nice place ? amazing! About “rime ice”, we would face this problem in the same way as regular wind turbines, which heat the surface of their blades to avoid the ice. In our case, the alternator is inside the structure and on the middle part, so we have thought that it will be possible to derivate some energy from the alternator or even let its natural energy leaks (heat leaks) to heat the mast’s surface. Of course, it depends on how cold the air surrounding is! About survival wind speed, I’m afraid that for current Vortex Tacoma units (2,75m high) 60 m/s is just too much; weight and material’s thickness and toughness are designed for winds from 3 to 10 m/s, which is the most common wind range around the world, and a survival speed of around 30 m/s. Of course, in the near future bigger devices will be ready and calibrated to work with higher wind speeds. Vortex technology may be feasible in the future for those specific conditions you mention, but I’m afraid that current devices we are developing are meant for less aggressive environments.

      One of the greatest challenges of both wind and solar is how it performs in low wind conditions (and light, for solar). Your generators start from 2-3 m/s, but … with how much? Looking forward to see a curve with wind vs output.

        Thanks for spotting the typo! The lock-in range (wind speeds working range) can be calibrated to be lower or higher. Normally, small wind generators have their nominal output corresponding to higher wind speeds than the ones you can usually find. We wanted an aerogenerator which can be working for a longer period of time, so designed it to reach nominal power output at normal wind speeds, which are commonly between 3 and 10 m/s. Our goal with this tech is to make it an equivalent in wind power of solar power, similar in features and costs. Currently, we are working on a power curve and an energy curve for a datasheet of Tacoma units, also conducting a research along the Czech Technical University of Prague to estimate cost-effectiveness and feasibility of the technology costs over a long time.

        Calculations and trials reveal that most common oscillatory frequency is between 4-10 Hz, which is too low to be heard. On most wind tunnels you cannot perform proper sound measurements since wind is loud and turbulent inside. On field tests, we directly haven’t heard anything at all from the devices while functioning. Anyway, this kind of data is hard to be measured when you have more than one source (the wind, the device and the surrounding objects). The certification and further trials will tell an exact number of dB, although current certification methods are designed for blades-based turbines and may not be feasible for our technology. Full environmental impact researches are the next step in this matters.

      Hi Vortex Team,

      It’s really nice to see the update. Eagerly waiting for your first commercial vortex blade and if it could be available in India as well.

        Hi! Thanks! To develop a brand new technology is a hard and uncertain journey. We are now in homologation stage of the units and getting ready to reach the market next year if everything goes as expected! About India, we will start selling in Europe since you need proper post-purchase services and installation agreements to do this well. We will reach worldwide market asap.

      We are looking into a 2 MW blade wind mill. I understand that the rated output of the Vortex Bladeless is in the order of 100 w.
      Have you advanced in higher output units?
      Do you think that, in a near future, this will be possible?
      I will appreciate your reply.
      Best regards.

        Hello! Since new manufacturing methods have to be created and pieces have to be homologated and certified before selling, we decided to enter in the market humblely and from below, only option for us as a startup. This 100w devices are intended to be micro-wind energy for end-consumers / distributed energy on small or private grids. As costs of the turbine are going to be low and they need a very small space to work, you can install more than one Vortex turbine to generate more power while keeping cost-effectiveness compared to regular wind turbines. Further research has to be made to measuse this exactly.

        Anyway we are not going to stop here and continue developing bigger devices to be competitive with regular wind industry in the future. By now our main “competitors” are Solar Panels more than small wind turbines, as we are more similar in features to solar panels than to conventional windmills.

      What does a Vortex Bladeless sound like, and how loud is that sound?

      • Vortex Bladeless
        Posted at 11:58h, 13 July Reply

        Hello! If the device is proper callibrated and anchored we have not heard any sound at all during tests. The oscillation frequency of Vortex Tacoma (2,75m) is measured between 4 and 10 Hz, which is too low to be heard by humans or animals. At the moment we believe that Vortex units will be completely silent on its operation in any conditions. Calculations estimate that some harmonic waves generated by the wind itself when passing throught the device can weakly resonate in higher frequencies. But further field tests have to be conducted.

      Hello Vortex team! It is so exciting to hear of the progress you are making. While I don’t fully understand, not being a technical person, I can see a time when your product will be used around the world. Our Government here in Australia is still plugging coal and coal seam gas instead of renewable energy – how short-sighted and greedy they are! I myself have solar panels on the roof and mostly put energy back into the power grid. But I look forward to the day when every home and business has their own solar and Vortex power supply.
      I hope you are going to spread your technology far afield – even to Australia.
      Keep up the good work!!

      I have a flag pole at my small, urban house! I am no engineer, but thought it would be a great idea to replace flag poles with your energy producing device! It would be a double duty product, and basically unnoticed!

      Just a thought!

        Thank you for writing Dennis. Haha that is fun! but I’m afraid our wind turbines are way thicker than a flagpole. On the other hand if you tie a flag to the wind generator I guess it won’t behave properly since flags are affected by the same physical principle that makes our turbines work, there will be some kind of interference!

      Hello VORTEX Team,

      when your products will be ready for sales? also any estimate of the price in $ per kw.

        Hello Mahmoud! As you can read in our FAQs, Vortex Tacoma (2,75m) is in process of certification and will be available in the market as soon as we can start mass manufacturing them. Prices for this model as a commercial product cannot be calculated yet since it mainly deppends on manufacture costs and agreements with materials providers, which are in process now. Vortex Nano (1m) will be “sold” as a beta testing unit on its ex-works price the incoming months, for testing and feedback purposes. More info about this will be announced soon!

        Hello Juan, thank you for writing. We don’t want to announce a price for the Tacoma model yet because agreements for mass manufacturing and prices of the pieces and ensambling cannot be made until the certification process is over. We want them to be competitive and as affordable as solar panels, but it truly deppends on the manufacturing and materials costs. Anyway we will have to announce a price for end of this year.

      Hello there,
      I follow your works for a while now, and like many other innovative projects, the same information is missing :
      – estimated date of commercial launch for each model, actualized every 3 months
      – estimated cost of each model, actualized every 3 monts
      – estimated ROI of each model, actualized every 3 months
      As potential and early buyers, we don’t complain if those figures will move in the future, we perfectly know that research and industralization can raise many issues.
      However, we like to read that you’re not just researchers, but have a solid planning and commercial targets in mind, and have enough courage and confidence to show them.

      All the best and best wishes to suceed !
      Eric / France

        Hello Eric, thank you for writing. Unfortunately that info is not available yet, I will try to answer you as good as possible: 
        – Commercial launch: Unknown, the certification process with the EU takes at least 6 months, then manufacture, then distribution and finally selling, it is a very long process. We want the units to be in the market as soon as possible, in fact if they are not in the market for 2019 I’m afraid that the company won’t be able to keep developing on its own without funding. So products have to be launched soon or this project will die, but really cannot say when.
        – Estimated cost: For the prototypes we are making now, some pieces are made here and others made by other companies, mainly 3D printing on carbon fiber and resins. We know that those pieces could be mass manufactured in a cheap way, making the product very competitive, but the agreements for that can’t be made until the certification and the long term testing with the EU reveals that the geometry and pieces we are using now are really the correct ones. Our goal is to make them as affordable as solar panels.
        – ROI: Without the previous one, we cannot know this one. We can say operative and maintenance costs of Vortex turbines are very low, so cost-effectiveness is estimated to be better compared to regular turbines. In terms of ROI for energy generators, it deppends on how expensive is energy in your place and the wind conditions of your place.
        When you develop a new technology you have to test and test again literally everything, even the smallest thing. We are worried about the market and commercial targets but we are more worried about obtaining the best technology possible because if something fails at the certification stage, we won’t have a product and those market issues won’t matter. You will find more detailed info in our white paper

      How high should a system be to generate. 6kw peak power?
      Is it something you are working on and what is the cost?

      • Vortex Bladeless
        Posted at 09:32h, 04 July Reply

        Hi Jens! Talking about 6Kw of nominal output, approximately more than 20 meters high! The bigger the device, the better performance (less leaks), and the power generated is proportionally multiplied by cubed height. We are working in Vortex Tacoma as our main product in the future, with 2,75m high and 100w nominal output. There is no cost decided yet for the commercial products, we want them to be as affordable as solar panels, but that depends on manufacture costs and the agreements with providers of materials.
