npub15zu89j2k6sja8qgcs5qdu2pfra5kemhlgeern2cpcw2svkuvkudqu3s7lx (npub15zu…s7lx) I don't understand the hype for these.
Let's take a pumped storage plant (e.g. Limmern, which I recently visited and highly recommend visiting). It can switch between storing 1GW and re-injecting 1GW in some three minutes. If you wanted to achieve 1GW by stacking concrete blocks, you would need to lift 500 blocks of 1m³ of concrete by a 1000 m each *every second*!
Stacking blocks does not scale, pumping liquids does.
