Notations 1. Back pressure between supply and shower head was remarkably high which made an enclosed paddle system near impossible without some re-circulatory system. Immediate need for results resulted in evacuating pressure. 2. Inferior dc-motors are hardly efficient for this exercise which romanticizes that having achieved average 6.0 volts here, more efficient generators certainly could light bathroom fixtures for a shower powered by the shower. 3. Envisioning a venturi like propeller insert with magnetic poles to rotate an exterior cylinder to generate electricity --> some day.
