Abstract: Methods and associated systems for storing compressed air and extracting energy from the compressed air are disclosed. An exemplary method comprises: compressing air; storing the compressed air in a first storage tank at a first pressure; transferring the compressed air from the first storage tank to a second storage tank; storing the compressed air in the second storage tank at a second pressure lower than the first pressure; discharging the compressed air from the second storage tank; and extracting energy from the compressed air discharged from the second storage tank. The method may also comprise adding heat to the compressed air between the first storage tank and the second storage tank.

Abstract: A wind turbine has a plurality of blades mounted on a rotor, the rotor has a rotatable shaft with a drivewheel extending therefrom. A plurality of wheels are in continuous rotatable contact with the drivewheel and are connected to drive a plurality of generators to produce energy. A controller is connected to control the number of generators that are generating between zero and all of the generators based on the speed of the blades. A method of operating the wind turbine uses a controller to control the number of generators that are generating based on the speed of the rotor.

Abstract: A wind turbine and method of operation thereof uses a plurality of generators and a controller to control the operation of the turbine based on various parameters. The generators are each smaller than the total power capacity of the turbine and the controller adds more generators or removes generators based on the speed of the rotor. The controller loads and unloads the generators, which rotate continuously when the wind turbine is operating.

Abstract: A wind turbine has a hub mounted on a rotatable shaft with a ring concentrically mounted on the shaft. The ring is connected to drive wheels, which in turn drive generators to produce electricity. A controller is connected to control the speed of the turbine by controlling the number and force of contact between the wheels and the ring and also controlling other components such as the pitch, yaw and brakes for the turbine while monitoring the wind conditions.

Abstract: A hydroelectric power plant uses a plurality of windmills connected to compressed air generators to produce pressurized air. Pressurized air is used to drive water through a turbine to produce electrical power. The water is recycled and the power plant includes reserve pressurized air tanks to allow the plant to continue to operate when the wind levels are not sufficient to produce high pressure air. The power plant is designed to be operated on a continuous basis based on wind power. When the wind subsides and the reserve capacity has been exhausted, electricity can be drawn from the local utility supplier. When excess power is generated by the power plant, electricity from the power plant can be added to the grid of the local electricity supplier.
