It doesn't make sense to invest so much land, machinery, and labor into something that generates and stores so little energy
- vanattab 6y agoWhile I don't disagree with your general sentiment of the viability of gravity batteries. I don't think its a very good comparison. One is all about electricity generation and the other is all about storage. If gravity batteries ever become used in practice it would probably be in tandem with solar. You would charge the battery during the day off solar and allow it to discharge at night when there is no sun to stabilize the grid.
