Abstract: A portable hydroelectric generator. The portable hydroelectric generator includes a flywheel adapted to rotate from a flow of water, turning a driveshaft and powering a generator. The flywheel is brought to an initial rotational speed from an external power source or from electricity stored in the battery. The flywheel rotation is maintained with a flow of water from a pump which moves water from the bottom of the housing to the blades of the flywheel. The rotation from the flywheel to the generator produces electricity. The generated electricity is stored in a battery, which provides power to an outlet as well as to the pump. Additionally, the generator can include a solar panel to provide an alternative source of power for the initial rotation of the flywheel.
