There are a bunch of other technologies as well. Huge flywheels [1], which are supposed to be used for very responsive power needs (i.e. grid stabilisation), trains loaded with weights which get pulled up a mountain and released [2], redox-flow batteries and so on.

- jandrese 6y agoI wonder what the local zoning commission has to say about the guy building a personal toxic metal death ray in his backyard?
- peteradio 6y agoThat is why I will never live in a HOA neighborhood.
- jandrese 6y agoThe zoning commission runs at the town/country level, so even if you don't have HOA busybodies you still need to get the permits. The law is usually worded such that if you're doing something abnormal you don't get a "there is no rule that says a dog can't play baseball" loophole, you instead have to bring it up before the county council and justify the project.
- taeric 6y agoSeems the train idea is similar to the old counterbalance system for trollies in Seattle.
- imtringued 6y agoHydro pump storage works because you don't have to pay for the weights. Building a train is worse than batteries in terms of economics.
