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

How it worksResonance 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!

    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!

    I am living in the Netherlands. I have a brick wall on my house where it seems nearly always to be windy (other houses nearby create a venturi effect) . Would it be possible to anchor the Vortex Tacoma to this wall. Regulations do not allow to alleviate above my roof (at 10 meters).

    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!

      We just uploaded a brief research from the University of Prague about cost-effectiveness and feasibility of Vortex turbines, find it here.

      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 🙂

    Hello! Thanks for the good work on sustainable energy! I hope that Vortex Bladeless will be an financial and environmental success. 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.

      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?

    Whatever you do PLEASE don’t sell out to a large corporate! Keep up your great work. I will follow your progress keenly.

    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.

      Hi! At current stage we cannot calculate a final price since industrialisation of the manufacture is not settled yet. Materials and production processes usually change to jump from “prototype” to “final product”. The more effective the manufacture, the lower the price. We want this tech to be an equivalent in wind energy of solar energy on features. A goal of Vortex is to enter in the market with a price similar to regular solar panels 🙂

    Interesting technology.
    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.

    You say it is quiet. What sound measurements have been made?

    • Vortex Bladeless
      Posted at 12:22h, 13 July Reply

      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 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!

    What is your estimated price tag of a Tacoma 12 Kg, model and generation power of same at differenttwind speeds?Pls comment. Thanks.

      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.
