Water purification and compressed air energy storage

visit channel home
Total Economy: 0 USD
My take on a system for water purification and energy storage. No moving parts, long lasting and also functions as a pump. An array on a steep hill or cliff in warmer regions can cost effective produce clean water and energy simultaneously. The compressed air energy stored can then power all kinds of pneumatic motors, no electricity needed. Steam water distillation is 99.99% pure free of bacteria biological contaminants or toxins. A diagonal 155 cm spot Fresnel lens can produce 1650 C and melt zinc, glass, concrete (decomposes), boil a liter of water in less than 3 min. https://bitcoinfiles.org/t/51acba053fee8278126be8f12d55aae86300e90d3c45769326ff9999ea55cb33
