Gravitricity - weight/gravity power storage

Piwoslaw · 05-19-23, 11:53 PM

I got this idea about small scale pumped hydro yesterday.
Instead of pumping water above the surface to store energy, why not pump it to the surface?
I'm thinking about a well, and wells can be tens or even 100 meters deep, so that gives quite a bit of head. On the surface would be a pond.

Of course, not good for all locations, since the well would have to be able to accept the amount of water that will be dropped while generating electricity.

Add a windmill that pumps water directly (like in old farms).

What do you think?
