Quietrevolution Helical Wind Turbine
‘The British start-up Quietrevolution developed a vertical axis wind turbine which is not only more aesthetic but is also better at gathering wind near and around buildings, which frequently vary in direction. The Helical wind turbine is also quieter because the blade tip speed is lower. [..]
According to quietrevolution the QR5 will generate around 10,000 kWh per year in a site with an average wind of 5.9m/s. This is equivalent to about five low-energy houses’ electricity demand, or the electrical needs of a twenty man office. Unlike other turbines which are usually noisy the unique shape of the quietrevolution turbine allows it to operate in near silent which is ideal for operating close to residential areas. [..]’
