Sauer Energy's compact vertical-axis wind turbine is quieter and generates electricity at much slower speeds, making it great for business and residential use.
Sauer Energy is challenging the commonly held image of fields of giant white horizontal-axis wind turbines with their new prototype, a relatively compact vertical-axis wind turbine.
The Sauer Energy design is not the first vertical-axis wind turbine to hit the market, but it has some singularly intriguing features. Sauer Energy's use of a dimpled blade surface makes the vertical-axis wind turbine more efficient at capturing wind from all directions. This produces sufficient torque to allow electricity generation at much slower blade speeds. A mere 6 mph wind can turn the blades enough to produce power, while allowing the turbine to run much quieter than the larger horizontal-axis models. The slower speeds are also safer for our avian friends.
Two of the most obvious benefits of the Sauer Energy vertical-axis wind turbine are its size and lightweight carbon fiber composite construction. Compact and relatively unobtrusive, the vertical-axis wind turbine can be easily integrated onto rooftops of homes and businesses. This results in a cost effective alternative energy approach because it removes dependency on a larger municipal power grid.
The unique design features of the Sauer Energy vertical-axis wind turbine is likely to make it stand out in the burgeoning micro wind turbine market, especially for residential applications.
