First Underground Windmill
Birds and bats have nothing to fear from a Minnesota startup company’s new underground windmill. Inventor Daryoush Allaei got the idea while working on a method of reducing vibration of conventional wind turbine blades. The new design he came up with works by funneling wind down into a tunnel in a way that increases its velocity before it passes through a turbine. Allaei compares it to a hydroelectric dam, which captures water and funnels it out through small openings. Computer models show the windmill design will produce 3 times more power than a conventional wind turbine, with none of the vibration and noise that requires windmill farms to be isolated from population centers.
