Abstract
Abstract Motion of waves is converted into energy in the form of compressed air which is stored in large containers. Compressed air flowing from the containers is utilized to drive turbinegenerators to generate electricity. The turbine-generators are selectively driven by stored energy which may be controlled. Generation of electricity may be varied to meet the demand regardless of the tides or the state of the waves.
