Abstract
A system for recovering the energy from atmospheric wind wherein a windmill operates a compressor for compressing air which is stored in one or more tanks. The compressed air is used to drive a prime mover coupled by gear means to an electrical generator or other work-producing apparatus. The prime mover is operated by hydraulic fluid responsive to the application of the compressed air to fluid tanks by valve means responsive to the operation of the prime mover. The compressor has a unique means for lubricating the same. Alternatively, the prime mover can be operated by conventional water pressure during periods of little or no wind.
