Abstract
An electric power generation system that includes a platform positioned above a water surface, an anchoring system to secure the platform to a floor below a body of water, at least one turbine extending below the platform to harvest underwater ocean currents and at least one electrical generator positioned upon the platform for outputting electrical energy. The turbine includes a rotatable shaft and a plurality of rotatable blades connected to the rotatable shaft. A first rotational axis of the rotatable shaft is vertically oriented and wherein a second rotational axis of the plurality of rotatable blades is horizontally aligned with an underwater current stream. The electrical generator is mechanically connected to the shaft of the turbine to convert a rotational torque of the shaft to electrical energy.
