Could free energy be only one flush away?
Could free energy be only one flush away? Hydroelectric power has never been a small operation. Dams constructed to capture energy from massive amounts of moving water supply about 25 percent of the world’s electricity [source: Bonsor]. The concept is fairly simple: Moving fluid has energy. In this case, the fluid is water, but wind turbines work on the same principle using air as the fluid. So, place a series of turbine blades in the path of rushing water, and the water is going to spin them. In spinning the blades, the water is transferring its energy to the turbine. The turbine then transforms this energy of movement into electrical energy. In its simplest form, the rotati
