The Aeroleaf ® is a patented micro wind turbine composed of a double blade with a vertical axis in a shape of a leaf and a synchronous microgenerator with permanent magnets. Driven in rotation by the blade, without belts or gears, the magnets pass in front of the coils and thus generate an alternating current. This is immediately rectified in direct current to be able to sum the currents. The Aeroleaf have an aerodynamic profile optimized to exploit the weakest winds (from 2.5 m/s of wind) as well as the strongest (up to 43 m/s continuously, 50 m/s in gusts).
