In addition, flexible and fully recyclable organic solar panels have been used, reinforcing the project's sustainability. Thanks to this initiative, carried out at the Breña wind farm in Albacete, the wind turbines have electricity to supply the turbine's internal systems, even without wind. One of the most exciting avenues of research in recent times is the addition of solar panels to windmill masts. ![]() ![]() Innovation in the wind energy sector is not only limited to new designs or anchoring technologies in the case of floating offshore wind power but is also aimed at improving the functionalities of existing wind turbines. Hybrid wind turbines: when sun and wind go hand in hand Who knows if, combined with solar farms on rooftops and solar glass, they will become an ally for greener and more sustainable cities. By the end of 2022, they will test the feasibility of a wind turbine between nine and ten meters high. The company has so far carried out several installations in universities and town halls in the province of Ávila, but a commercial model is yet to reach the market. In addition, it does not require a specific orientation to generate energy, and unlike wind turbines with blades, several units can be installed next to each other without interfering with each other. The main model, on the other hand, is designed for installation on urban rooftops, as it is very quiet and can operate in turbulent winds. They are also studying the creation of smaller models of sixty centimeters in height that would be used to charge sensors in remote areas. The prototype they have developed has been named Tacoma -in honor of the mythical bridge that went into resonance and jumped into the air- and has a height of about three meters, a weight of fifteen kilos, and an electrical generation capacity of 100 watts. The inventors of the technology call it a "tuning system." The stronger the wind, the greater the amplitude of oscillation. However, the distinctive feature of these new wind turbines is that they use a patented mechanism with magnets that modify the stiffness of the cylinder depending on its oscillation amplitude and the degree of core flexing. This means that a standard fiberglass mast only resonates when the wind blows with a certain intensity. The fact that there are no rotating parts reduces maintenance and component wear.Įvery material with the ability to vibrate has a particular resonance frequency. Technically, it is not a turbine, as there is no rotating element.Įveryday materials such as fiberglass or carbon fiber are used, which facilitates their construction. The cylinder oscillates in a specific wind speed range and then transforms the mechanical energy into electricity utilizing an alternator. The new bladeless wind turbines consist of a fixed vertical cylinder on an elastic rod attached to the ground. This is technically known as vortex shredding. A Spanish company has resorted to a concept called aeroelastic resonance to create masts without blades that generate electricity through vibration.īy way of a brief explanation, when air passes through a circular structure, vortices are created along its path, and when their frequency matches the resonance frequency of the structure, the latter begins to absorb energy. However, there are more radical solutions, such as dispensing with any rotating element. One of the ways to achieve more compact wind turbines would be to opt for vertical axis turbines, i.e., turbines that rotate on themselves. How can this be solved? Bladeless wind turbines: aeroelastic resonance However, these structures are bulky and not very functional in urban spaces, especially for self-consumption. As far as this type of green power is concerned, wind turbines based on blades have unbeatable efficiency. It's a sign of the potential of offshore wind energy, which is exploring revolutionary designs like this pyramidal turbine we talked about recently. It will generate 16 MW, enough to power 20,000 homes, and have 387-feet blades while standing 866 feet tall, almost shoulder to shoulder with the French Eiffel Tower. ![]() The world's largest wind turbine is expected to start operating in 2026.
