ABSTRACT:
A tide-operated turbine is located in a holding tank having communication with a tide-fed reservoir so as to supply the turbine with operating water. To provide continuous, around-the-clock operation of the turbine by insuring a positive operating head throughout tidal cycles, a control system causes the turbine to discharge into the ocean through a turbine discharge port in an ocean-fronting wall of the holding tank at times during each tide cycle when the tidal level is below the discharge port, but closes the discharge port and causes the turbine to discharge into the holding tank at times when the tidal level is above the discharge port. The control system also provides drainage of the holding tank during each tide cycle.
