SolarMill overcomes the challenge of solar power only being available at certain times of day, and in clear weather. It also addresses wind power limitations such as noise pollution, wind reliability and the need for large and costly turbines. Featuring mechanical braking at high-speed winds beyond 18 m/s and presenting no threat to birds or wildlife, SolarMill’s turbine design lends itself to scalable and modular configurations on rooftops, communications towers and even on boats and as mobile units.
