Water is always a prevelant source of energy. By making new uses for water, we can both purify, and produce energy at the same time. Although it may become a issue to develop new sources to provide power, we can create lakes and streams to power systems.
1. Develop the cut stream idea, of cutting streams from major rivers, running them throuh a course that connects to a water system, and then re route it back to the main river.
2. Make temporary water system to harvest water from flood areas, that can remove the water, and produce power from it by running the water through the system, then evaporating it.
