  • Patent number: 11215164
    Abstract: A green wind turbine system that provides continuous rotation of a propeller, to prevent stopping or critical slowing of the propeller to, which causes damage to the bearing and gear assembly, and shortens of the turbine life. The propeller includes at least two opposing hollow blades, each having a pair of reservoirs positioned with one at the tip and stem, and connected by a fluid line; a wireless hydraulic pump with a rechargeable battery, and a wireless control unit configured between the reservoirs to pump fluid that is heated and/or with anti-freeze between the reservoirs; and a nacelle with: a motion sensor, anemometer, heated reserve tank. The propeller is made with biodegradable materials; and the turbine is able to manipulate the reservoir fluids to create an imbalance within the propeller to prevent it from stopping in low or no wind conditions; and to slow down in high wind conditions.
