Create Light with the Power of Water User Friendly High Quality Demonstrate how the power of water can be used to produce clean energy. Water pressure from your sink faucet churns the turning blades, creating enough energy to power an LED bulb when the optimum water pressure is reached. The open design of this water turbine allows students to clearly observe the motion of the blades and the energy-producing action of the dynamo. Required but not included are a hose and water source
