The ES Pipe Waterwheel is created by Korean innovator Ryan Jongwoo Choi. The concept works as a mini turbine to harness hydropower from regular water taps and converts it to energy. However this energy is for a specific use; to power specialized bulbs. The intended area of use is a country like Africa where there is severe power shortage. On paper, the idea looks good enough to execute, however how large scale can this go, remains to be seen.
