Patent ID: 8841790

Claim:
A system for producing electricity hydrodynamically, comprising: a viaduct through which vehicles traverse, the viaduct being formed from multiple pairs of roadway spans, each roadway span including two feet and two tenons, a first roadway span of a first pair of roadway spans being supported by two columns from a first quartet of columns, the two feet of the first roadway span transversely resting on the top of the two columns while the tenons of the first roadway span mate with U-shape mortises of the two columns; and a hydrodynamic array configured to support the viaduct and further configured to generate electricity from the motion of ocean tides or river currents and forces acting on the hydrodynamic array, which is immersed in the ocean tides or river currents, and which is in motion relative to the ocean tides or river currents.
