The next world's tallest building could be a 3k-feet-high battery
- w-m 2y agoSo they want to build a hollow structure, 1 km high, with all its weight concentrated at the very top (when charged)? How is that supposed to not immediately collapse?
- GuB-42 2y agoIt is possible if the weights are not too heavy. Does it make economic sense? Probably not.
- Etherlord87 2y agoIt probably makes economic sense considering the marketing.
- inhumantsar 2y agoit's not a hollow structure, it's space set aside in an otherwise normal commercial/residential tower. like extra banks of elevators. even if it weren't though, the weight of the building would far outweigh the weight of the blocks.
- Qem 2y agoCouldn't we just hollow out mountains to form very tall, deep lakes, and then pump water in and out to use as a battery? Say, a water cylinder 200m wide and 1000m tall holds approximately 43GWh of potential energy.
- mech9879876 2y agowhat a silly idea. Never gonna be economical. Pump water uphill for gravity energy storage. Dont use traincars or elevators or human-built elevated structures.
