The moving mass batteries are interesting
- WJW 5y agoInteresting technically but not really economically. Gravity is just not a very strong force compared to chemical bonds so you need humongous amounts of mass and a fairly large height difference to store an equivalent amount of energy as a few containers worth of batteries. There is a reason that even though we've had the technology to make moving mass batteries for decades, the only form of such energy storage in operation today is pumped hydro.
