Abstract
The invention provides a pair of co-rotating fluid powered wheel and generator pairs each rotating about a single vertical axis. Each wheel/generator is mounted on a respective axle one of which is solid and the other tubular. Separation of fluid flow into 2 streams engages the wheels for rotation in opposite directions. Folding paddles collapse and extend to engage the moving fluid.
Claims20
A water wheel generator comprising:
- a first water wheel and generator pair mounted on a first vertical axle for rotation about a first vertical axis;
- a second water wheel and generator pair mounted on a second vertical axle for co-rotation with said first fluid wheel and generator pair about said first vertical axis;
- wherein said second vertical axle is adapted for rotation about said first vertical axle;
- wherein said first and second water wheels are mounted for immersion in a stream of moving water;
- and
- wherein said first and second generators are both mounted above said first and second water wheels and out of said moving stream of water.
