Why is Hydraulic Rock Storage not viable? : r/AskEngineers
It is called Hydraulic Rock Storage. There was a Tedx on the subject a couple of years back that was cross posted on r/askengineers here where it was basically dismissed for several reasons. Those reasons being you would need a massive rock to store a usable amount of energy, you can''t build a smooth enough piston and would lose a lot of energy
