I think i came up with a breakthrough.?

Question

If you put a water spinning wheel, just below a waterfall, The water would spin the wheel, creating a non polluting source of energy, and would not disturb the waterfall. What do you think?

Answer 1

Its been invented already, where, but placing it at the bottom of the waterfall, the stream would slow it down, and the water from the top would have dispersead far too much...

Good for powering a 12 V applaince

Answer 2

Thats commonly known as hydroelectric power.

For example, a lake in the mountains can be connected to a near by city with an aqueduct. The water in the lake has potential energy that is converted into kinetic energy as it falls. The fast moving water flows through a turbine, generating electricity.

Water wheels have been used for thousands of years.

As for it not disturbing the waterfall: I fail to see where you could put the water wheel without interfering. At the top, the waterfall becomes rain. At the base, you get mist (and inefficiency as the water speads). Downstream, you get significantly less flow.

Answer 3

I think it has been done. Much of the water of the Niagara river actually bypasses the falls and goes through turbines to generate electricity. But a water wheel in front of the falls would be unsightly and not be as efficient ans the enclosed turbines either. In fact the first hydroelectric power plant was built at Niagara Falls in 1896. Hydroelectric power generation is one of the oldest, cheapest and cleanest forms ways of generating electricity. But every river and waterfall big enough to produce enough power to bother with has already be harnessed.

Answer 4

Already invented (and it will disturb the waterfall, if it didn't it wouldn't produce any power).

There's also the fact that you can only as much energy out as the kinetic energy of the falling water which depends on how high your dam is.

Answer 5

Small scale hydroelectric. It's been around for years. In practice, a turbine is more efficient.

Answer 6

Usually called an overshot water wheel.
if your really good with your hands you may could make a turbine

Answer 7

We like to call that the Hoover dam. try watching the history channel some time ok?

Answer 8

that is an old idea
but dont talk about water
it makes me want to look for a tree

Answer 9

You are 3000 years too late.

Answer 10

i came up with one too. if the grass gets too long, i came up with a device that i will call a lawn trimming machine, no wait i will call it a lawn mower. it can cut the grass evenly when to long. what do you think?
