Instead of pumping water up hill.

Or on a large scale:

Oddly, they supposedly broke ground in 2020, there is a short video clip of construction (moving dirt), and then nothing.  I could just be unable to find current information.  Maybe I should try Google Earth to see if it shows anything in Pahrump, NV.

Probably won't see it yet. Google earth images are  ( updated every years)
This is where it is supposed to be. They scaled it down from initial design.

The thing I realize about gravity batteries is that the demand from the load must control the drop of the weight. No demand the load weight stops, the more demand the faster the weight drops.Otherwise there could be wasted power

I hadn't thought about that.  Wouldn't lower demand result in less resistance from the generators which would cause the weight to move faster?  And if you used brakes to slow it, you'd be wasting energy.

That's true. But I keep seeing the weights moving down ( discharging the gravity battery) without a load. It's not as perfect as I originally thought.

Maybe if you have two weights, one could be falling(discharging) and one could be raising ( charging)  if there was power left from the discharging one it could be fed to the raising motor.
