Quietrevolution (VWT Power Limited)
The Quietrevolution qr5 is a vertical axis wind turbine, designed specifically for environments close to people and their environment. The design eliminates downtime from changing wind direction due to vertical axis design, possesses an aerodynamic helical blade design to minimize vibration, and has quiet operation to allow for installation in public places.
Targeted countries include: United Kingdom, Germany, Ireland, France, Belgium
