System to harnesses the energy of rainwater

    The idea is to create a microturbine able to harness the rainwater runoff from roofs to generate electricity.
    The system will feature a microturbine measuring about 2 inches wide by 10 inches high designed to be placed in half-inch pipe. As the turbine is spun by the flowing water from rooftop gutters, it will generate enough energy to charge 12-volt batteries that can be used to power small household devices.
    As an added benefit, the water flowing through the turbine will also be sent through a charcoal filter and into a storage tank, purifying the water to some level.
