Scottish company, Renewable Devices designs and distributes what they say is “the quietest rooftop wind turbine currently available.†The small footprint, Swift Wind Turbine, is designed for both commercial and residential use.
The 7′ diameter turbine produces 1.5kW @ 14 m/s, or roughly 2,000 kWh per year (roughly 20% of average home use) and requires about 2′ of roof clearance.
!ADVERTISEMENT!
Commercial installations can consist of multiple units. Wind energy is dispersed along the blades to outer ring which acts as a ‘diffuser’ creating less noise. U.S. based, Cascade Engineering, will manufacture the turbines blades and assemble all the units sold in the U.S.
Installed, this turbine will run you $10,000 to $12,000.
