Hello all, What a great idea that they could have invented was soon lol. The Korean designer Jongwoo Ryan Choi, a utility created more for the water that comes from the tap in our homes. He developed the product ES Pipe Waterwheel, which works with a generator turbine shaped inside the tap, turning as the water passes. Each time that one rotates the tap energy is generated, which can be stored in lamps placed in the tube. These lamps can be removed to illuminate a room with the accumulated energy. Small savings at the end of the year makes a difference, I liked the idea and you, adhered?
