⚡️ Why is water storage not used as natural batteries on earth? Pump water up into a reservoir with excess energy, then when you need energy let it down through a dam with electricity generators. Efficiency is like 80% most likely, but it works forever and doesn’t hurt the environment. This can work in 100 years, batteries need to be exchanged all the time. I know it’s used sometimes, but I don’t understand why not on bigger scale. 🔗 Join us | @MyLordBebo
