Even a small yield of 50 watts equals 50 x 24hrs =1.2 kwhs. If you have no head available but you have a large enough stream / river, you would get more  power from a tethered prop style hydro unit then you would yield from any pump/storage/hydro scheme. There is just too much loss from energy conversion to make a pump/storage/hydro setup worthwhile. If your curious about hydro yields for different heads and flow , you can use the online calculator at  

The basic formula for a boat: Does it displace more water by volume than the mass?

Same kind of thing with hydro power: the question is about mass and pressure.

The potential energy of a reservior is essentially flow x mass/friction.

How do you do yours?
