Abstract
A system for deriving useful energy from a windmill in which a liquid pump is driven by the windmill. Useful energy is obtained by either a fluid driven generator or a friction heater. The output of the pump and the speed of the windmill are controlled by a constant volume valve in the fluid circuit.
Claims5
A system for extracting useful energy from the wind, comprising a windmill;
- a closed circuit containing a liquid;
- pump means driven by said windmill to place said liquid under pressure in said circuit;
- and a flow control impedance to permit a predetermined constant volumetric flow of said liquid in said circuit per unit of time and across which said pressure drops to yield heat.
