Abstract
Abstract A plurality of tidal chambers are filled in succession during rising tide and then are allowed to sequentially empty during the half-cycle of falling tide. Power is generated by air flow across a turbine, as a manifold and valve means communicate air pressure from the tidal chambers during rising tide and vacuum pressure during falling tide. Sequential operation of the tidal chambers permits continuous generation of power during the full cycle of rising and falling tide.
