Abstract:
A fully-submersible apparatus for generating electricity from generally liquid flow, comprising:a buoyant structure having a liquid receiving chamber, a first side portion, a relatively spaced second side portion, a top portion attached to said first and second side portions, and a bottom portion attached to said first and second side portions,at least two pairs of counter-rotatable motors, each of said pairs having two motors being in relative overlying and underlying relationship, said overlying and underlying motors having a common rotatable shaft and a plurality of generally radially oriented vanes each having a plurality of rotatable subvanes, whereby said liquid flow will effect rotation of said vanes and said shaft,vanes of said overlying motor are angularly displaced from said vanes of said underlying motor,said subvanes structured to rotate between a closed position wherein the vane will provide a generally continuous wall which resists liquid flow therethrough and an open position wherein said vane will have openings permitting passage of liquid therethrough, andgenerating means responsive to liquid flow established rotation of said shaft to generate electricity.
