ABSTRACT:
An improved hydroelectric system provides automatic adjustment for both tidal (reversing) and river (one way) type flow. A plurality of parallel, axial flow auger-type impellors are mounted in a horizontal plane on a floating, inverted-dry-dock type vessel that has an upper deck mounting hydroelectric generators. The vessel has no bottom beneath the impellors but has parallel with them on each side a tank for buoyancy and level and flow control. Over and under the impellors are pivoting deflectors that direct flow onto the impellors and automatically reverse and rest against appropriate bumper stops when the flow reverses, from one open end to the other open end of the vessel.
