Abstract: A lunar tide powered hydroelectric plant of variable size and power generation capacity for basing on land or in tide waters. The basic collection of mechanical power is done by torsion spring bank units positioned on a concrete barge. The land-based plant obtains oscillatory motion from a notched frame. The tide water based plant obtains oscillating motion from notched piling. An individual torsion spring bank unit can comprise columns of horizontally aligned torsion springs based on a row of torsion springs of a bottom control cell. The tidal and wave motion is transferred to the torsion spring banks. A computer system manages the release of each torsion spring column to a drive shaft of a generator to produce electrical power. The computer system also permits the conversion of kinetic energy by reversing the gearing system for the upward motion of the floating barge so as to obtain a constant input of kinetic energy to the generator.
