Choosing WhisperRing®!
Your contribution to the climate
Wind energy is one of the most important energy sources today and plays a major role in achieving the goals of the Paris (2015) and Glasgow (2021) Climate Accords. To meet the rising demand for wind energy, more wind turbines are needed. WhisperRing® turbines operate more effectively than conventional turbines and can therefore accelerate the energy transition.
WhisperRing® wind turbines reduce the cost of wind energy, by increasing the efficiency of wind turbines. Moreover, thanks to efficient and automated production processes, turbine acquisition and installation costs are lower. As a result, even less tall turbines can be operated profitably. So good news in the face of constantly rising energy costs!
The design of the WhisperRing® is particularly human- and animal-friendly. Thanks to the lower rotational speed, collisions with birds and bats are less likely, the cast shadow is less of a nuisance and there is much less noise. And actually, the WhisperRing® looks a lot more fun, too!
The technologies used in WhisperRing® turbines are continually being developed in terms of performance, applied materials and manufacturing techniques. The manufacturing and maintenance process of the turbines is also continuously optimized.
What is not on it cannot be broken!
Thanks to the WhisperRing® patented annular generator and carbon design, a highly efficient wind turbine has been created with lower costs. The design combines proven techniques from aerospace, electrical and mechanical engineering. The result is an optimally efficient wind turbine that requires no hub, no nacelle and no gearbox.
No central axis
The WhisperRing® turbine has no central shaft. Instead, there is a ring with two halves rotating relative to each other, which incorporates the generator. The design eliminates the need for an expensive gearbox and large expensive magnets, significantly reducing weight.
High-tech materials
The turbine is made of Carbon Fiber Reinforced Polymeres (CFRP), a composite material of carbon fibers and thermosetting resin. The use of CFRP adds strength where needed and eliminates weight where possible. WhisperRing® carbon elements are easily produced and 3D printed, so to speak, based on the CAD design. Huge molds, as in conventional wind turbines, are therefore not necessary.
These materials can also be easily recycled after the end of their useful life.
Key facts
- Low energy costs
- The many different modules in the ring generator, can be turned on/off depending on wind speed
- Thanks to technologies proven outside the wind industry, the design life is as much as 30 years
- Low and easy maintenance thanks to carbon fiber reinforced composite construction
- Low noise level (59 m/s < 70 dB(A), while the current industry standard is 85 m/s > 100 dB(A)
- More than 80% weight savings due to the ring generator and materials used
- Minimal use of rare earth metals, such as Neodymium
- Reduced wake effect and thus more wind turbines possible per km2
- Patented worldwide
“WhisperRing has found a combination of technologies that together enable new levels of performance.”
