  • Natural turbulence electrical power generator
    Patent number: 4191893
    Abstract: An energy conversion apparatus is disclosed in which a stator, fixed relative to a watertight housing, is coupled to a rotor by a helical spring which suspends the rotor from the housing. Natural turbulence of a fluid, such as water or air, causes acceleration of the housing, and hence, acceleration of the stator. Inertia of the rotor, coupled to the stator through the helical spring and the housing, causes relative motion, both longitudinal and rotational, between the stator and the rotor, the rotational motion between the rotor, and the stator being used to generate electrical current.
