The new vertical axis wind turbine (VAWT) from Windation Energy Systems looks more like a HVAC unit than a wind turbine. But an installation of one of their 5 kilowatt wind turbines, at about $45,000 to $50,000 will recoup the investment in about 5 to 7 years.
Windation CEO and founder, Mark Sheikhrezai has said that he was inspired by ancient Persian buildings that used air currents and water reservoirs to cool the building. The design creates a difference in air pressure that helps create a steady flow of air. According to Sheikhrezai, the unit works very well with gusty inconsistent wind.
One of the advantages of this VAWT design is its ease of installation – the unit comes with its own inverter, and since all moving parts are contained, there’s no danger to birds, bats or people.
Windation plans to install one of their VAWT units at the Palo Alto Medical Foundation in California and expects to build more units for delivery this winter.
