minus-squareJacobCoffinWrites@slrpnk.netlinkfedilinkarrow-up4·3 months agoYeah pumped hydro needs lakes, not pools, as far as I know. They flood entire mountain valleys, using the surrounding mountains themselves as the storage structure, because they need so much space.
minus-squaresilence7@slrpnk.netOPlinkfedilinkarrow-up4·3 months agoYes, because phase transitions involve absolutely huge amounts of energy.

But a warehouse-sized balloon works?
Yes, because phase transitions involve absolutely huge amounts of energy.
