Abstract:
1. A submersible electrical power generating system including a generator means for generating electricity having a support means for positioning and maintaining said generating system in a flowing water current, comprising: a rotor blade means, oriented about a horizontal axis for rotation parallel to said water current where kinetic energy in said water current causes said rotor blade means to turn converting said kinetic energy into rotation mechanical energy, where said rotor blade means is functionally connected to a rotor shaft forming at its center the axis of rotation where one end of said rotor shaft is functionally connected to said generator means for transferring said rotational mechanical energy, and said rotor shaft has at another end a perpendicular pivotal support axial pivotally supporting said rotor blade means in a manner that a blade direction of said rotor blade means and a blade pitch of said rotor blade means can be adjusted by pivoting said rotor blade means around said pivotal support axial, where said blade direction and said blade pitch are adjusted by a microprocessor control center means configured: to get from a look-up table means stored in a RAM memory means of said microprocessor control center means an assigned blade direction for said rotor blade means and an assigned blade pitch for said rotor blade means; to determine if it is time for an adjustment of said blade direction of said rotor blade means and said blade angle of said rotor blade means; to get a real-time blade direction and a real-time blade pitch and compare to said assigned blade direction and to said assigned blade pitch; and to sequentially change said real-time blade direction and said real-time blade pitch to equal said assigned blade direction and said assigned blade pitch by reversing said blade pitch, increasing said blade pitch, or decreasing said blade pitch, wherein a data point corresponding to slack tide in said look-up table means causes said microprocessor control center means to reverse said real-time blade direction.
