Abstract
An offshore power generator includes an offshore platform. Current, wind, wave and other renewable energy generators are mounted to the offshore platform. Each current generator has a shroud enclosing a set of blades. A hub member is located within the shroud and extends in an upstream direction from the blades. The flow area between the interior of the shroud and the hub member converges from the shroud inlet to the blades.
Claims2
A current generator, comprising:
- a support frame;
- a generator mounted to the support frame, including a rotatable shaft, operatively connected to the generator such that when the shaft rotates, the generator generates electricity;
- a plurality of blades mounted to the rotatable shaft, capable of rotation in response to water current;
- an extension shaft, mounted to the generator and pivotally mounted to the support frame;
- a cone disposed upon the generator generally axially about the shaft to direct current flow to the outer edges of the plurality of blades;
- a power cable in electrical communication with the generator;
- and
- a wave generator mounted to the support frame, said wave generator comprising a buoy, a pair of pulleys disposed at either end of the buoy operatively connected to a generator disposed within the buoy, a pair of anchor cables mounted at one end to the support frame and at the other end to the pulleys to turn the pulleys, which in turn rotate the generator to generate electricity.
