Solar Aero Research, a New Hampshire alternative-energy organisation dedicated to energy independence and development of renewable resources, has been granted a patent for its bladeless, practically silent Fuller Wind Turbine.
The boundary-layer wind turbine is based on a 1913 Tesla patent, specially modified for wind generation applications.
Completely enclosed, the company claims its wind turbine addresses issues of noise, radar interference, aesthetic issues and wildlife injuries, while retaining high efficiency ratings.
The Fuller Wind Turbine only has one rotating component and no heavily loaded bearings. The turbine also offers lower maintenance requirements than bladed turbines and can be located at ground level while the turbine is supported on magnetic bearings, eliminating the need for routine maintenance carried out atop tall towers. Yaw bearings will be permanently lubricated.
Solar Aero Research says reduced life-cycle costs make the turbine desirable for urban rooftops and for use where support and maintenance infrastructure is limited.
According to an article on GizMag, the turbine will probably have a cut-in speed of about 3.5 knots and an optimum speed of around 20 knots. The smallest unit would be likely to produce about 5kW at 15 knots.
Solar Aero research claims the Fuller Wind Turbine will generate power at a cost comparable to coal-fired power plants and says production licenses are currently available worldwide.
