Because of that reason, many people are trying to find systems can be applied to make water to be a friendly energy source. The result is that they found it. Kinetic energy gotten from a turbine placed in the water results a friendly energy. But, unfortunately, to get a big energy it still depends on the water stream. The speed of the stream determines the energy amount. But, we can hope that it will result something helpful as alternative energy. |
