ABSTRACT:
A system and method for converting the energy of sea waves to useful power through the use of a buoyant float. This float is preloaded (i.e. submerged a predetermined distance beneath the level of a wave trough) and retained at that submerged elevation until such time as it is located beneath a wave crest. The float is then released from beneath the crest to rise through it and the flotational motion is converted to power. The system also provides for an upwardly directed preloading technique and combined systems wherein work is removed in both vertical movement of the float. Unusual gains in efficiency are achieved by this method and system.
