Abstract

A system for the capture of tidal energy has an off-shore docking component with multiple docking stations anchored or tethered not to drift with the tide, and moored to the docking stations multiple buoyant energy capture components having at least two hulls and disposed therebetween a submerged or submergible energy capture mechanism such as a vertical axis rotor, which energy capture components can drift relative the docking station according to the direction of tidal flow. The system can efficiently capture the fastest tidal flow near the surface, can be deployed in deep offshore and in inshore waters, is adaptable as to the form of energy produced and is not visually intrusive.
