Simple vertical-axis wind turbine

摘要

The wind turbine has four aerofoil vanes fixed at 45 degrees on a turntable. The turbine cools the air but does not change its velocity. The design relies on minimum disturbance to air flow so the turbine should be mounted on the ground. The turbine is simple and robust for high reliability and cheapness of construction and maintenance costs. The generator may be a direct drive generator or alternator with lithium storage. A wind farm may have several rows of turbines.
