The pump takes the water from the tank and pushes it to turn the cupped wheel then the water returns to the tank, so it never runs out of water.The cupped wheel turns the turbine creating electricity to operate the pressure pump and have enough electricity to power other electric devices. It can be built small enough to power a car, built big enough to power a small city, is mobile, and environment friendly.And like any wind turbine, it can be connected to the power grid or can be the main power supply for most applications. It is a fuel-free, endless supply of energy. So it can be applied in cars, small cities, Mars. outer space. It will cutback the c02 emissions by alot.
