Low Cost Free Energy Sand Battery charged from solar panels

This cuts down the cost of expensive batteries that use rare metals which are hard to mine and the working conditions are horrible. Batteries with rare metals cost this low (although their price is preety high compared with sand batteries for example) because people from the third countries mine them which are paid extremely low and work in terrible and dangerous mines. The price would shoot off the roof otherwise.
