Let's say we would take a pipe made of some very strong material, and connect it to the ocean at the deepest level possible. For example 500 meters. Then we would dig a huge area on land, again, as deep as possible. Lead the pipe to the lowest level of this huge basin we created and then use the pressurized water coming out to generate energy. Part of the energy will be used to turn the water into steam (so our hole never fills up completely), among other methods like possibly having arrays of mirrors pointing towards the basin, or choosing an area with volcanic activity where the used water is lead into to generate even more steam. We would be getting distilled water, salt and energy out of this process as I imagine it. So why hasn't it be done? Where did my thinking go wrong? It would seem like an almost infinite source of energy one could get out of this, without polluting the environment all while generating distilled water and possibly clouds which could be used to irrigate desert areas.
