npub1ev6llh68eggtr2k2wzc0jgstw9pzx57ra9e4l6gu5wsddnnwa0ms4wnh08 (npub1ev6…nh08) npub1s7us7gq9ywz9he2p57uj5jh484al6xru7was0tptnuq6w0kvyuuqk0t57s (npub1s7u…t57s) The problem with gravity energy storage is that gravity is such a weak force. A while back I saw someone figure out that they’d need two dams, each an acre in size, to replace a single Tesla PowerWall. I’m certain their calculation was off, though probably directionally accurate.
But yes, we need to do all the things (including batteries of all types - see recent announcements about research into “sugar water” flow batteries, for an example of non-toxic batteries) if we’re to decarbonise.
