Giorgia Burzachechi Here is the innovative wind turbine equipped with two counter-rotating rotors enclosed in a special duct that "tricks the air" and which makes it up to five times more efficient than traditional turbines. Silent and with reduced vibrations, it is ideal for urban applications thanks to its safety and low noise.

Vetar is a groundbreaking, world-patented invention that operates with the power of wind. It is extremely silent, non-vibrating, and generates greater power than standard urban wind turbines. The turbine has two double rotors that turn in opposite directions within a specially designed duct. This arrangement gives it significant advantages over any other standard wind turbine available in the market today.
How does it work?
The air is deceived by the turbine through advanced aerodynamics, creating pressures that drive the two rotors. A ring of high pressure is developed within the turbine, with a region of low pressure in its rear. Low-speed incompressible air enters like air going through a funnel and accelerates.
This is used by the two counter-rotating rotors and sped up, causing the turbine to become more efficient. This mechanism produces a minimum of 5 times as much energy compared to horizontal-axis wind turbines.
Efficient and quiet
Because of the double rotors that counter-rotate and cancel out each other’s rotational forces, the wind turbine produces far fewer vibrations than other designs. This aspect, coupled with significantly lower noise levels, makes it suitable for city use.
Urban turbine
The domestic wind business is developing extremely rapidly. As compared to the past, nowadays there are a lot of new ideas for harnessing wind energy even in urban areas that have weak or moderate winds, where old-fashioned turbines would require large rotors (which would take more space and create safety concerns). Clearly, wind is much less predictable than other sources of renewable power, like solar energy. For these ends, efforts are underway to create more efficient solutions, such as the spherical turbine capable of capturing wind from every direction or the quiet, compact Archimedes-inspired turbine.
This turbine can generate a lot of energy even with medium to high winds. But, most importantly, it produces very little noise and is far more appropriate for the city setting. It can be mounted on light poles, roofs, or even in your front yard.
