What's the best way to capture the energy produced by a falling object, and then use that energy to produce electricity for example ?

Like for instance, I've been thinking of a kind of water mill where it would be an object falling on the blades instead of water, therefore making the mill turn, but it probably would not make it turn fast enough to produce electricity. So is there a more efficient way to capture the energy of a falling object ?

After the object (or objects) has fallen once, how do you extract any more energy?

The reason watermills work is because they are taking advantage of the Earth doing work to continually lift the water back up (by evaporation). A watermill does not make energy, it steals it from Earth's natural processes.

I don't know what object(s) you are thinking of that would fall with regularity.
