Can i build one simple generator that is powered by wind or water? How?
I am testing wind and water for my science fair project. I need to add wind and water to the same generator and see which one produces more electricity. Does anyone have instructions for this type of generator, Since wind and water are similar types. THANKS!!!

The only "generators" I know that take both power sources are the windmills that were in use in Eastern North America around the 17th and 18th century.
They were "windmills" that were build right next to a river, at a point of great water slope (e.g., rapids), with a channel bringing the water through the base of the building.
The miller could choose to have the grindstone be driven by the water (paddles) or by the wind (from the wings); not from both at the same time. On one such mill that I studied, it was more often used with wind than with water.
The change of level in the water was relatively small and the wings -- driven by the wind -- were rather large. Therefore, if there was any kind of acceptable wind, that would provide more energy (to that particular mill) than the feeble river current.
