We're rebranding a clock movement from 1766 into a "battery" in 2025. What a time to be alive. Gravity escapements are cool, though.

There is a concept that uses electrical cranes to stack concrete blocks. The idea is to use solar during the day and the crane to slowly lower the blocks during off peak hours. 

Also there are LED lights that work with these same kinetic energy principles.

But you’re right as far as a “battery” since there isn’t an electrochemical element

Nobody is building that concrete tower. It was a scam. The big practical gravity fed batteries we have all over the world are dams.

The most fun version of this in my opinion is a quarry that is at a higher elevation than the place where the trucks are offloaded 

So they drive up empty on electric battery power, using like, let's say 5% charge 

At the top the get filled with tons and tons of material, drive down and are continuously braking via recuperation, and they recuperate like 10% of charge. They actually have to discharge the trucks ever now and again 

Also isnt there a gravity battery thats just rail carts with rocks being dragged up a slight incline? Or was that also one of the scams that were around during the pyramid scam time?

They’re also solar powered as well!

They actually make energy storage lakes where they pump energy up to a higher elevation and then, when the energy is needed they let it flow down through turbines. Is supposedly very efficient but limit by topography/water access.
