[RE-wrenches] gravity storage of excess PV generation

[Kirk Herander]

Happy New year All,

I'm sure most have heard of this technology, using excess PV-powered motors
to raise large weights to the top of a tower, then slowly lowering them to
release energy, the motors now rotating as generators.

I've only read articles of a few of these under construction on a utility
scale. I wonder if this has been tried on a smaller scale anywhere.
Thoughts? Resources? Thanks.
