Abstract: An energy conversion system which utilizes magneto-hydrodynamics for energy based on the Stirling cycle without any moving parts. The energy conversion system generally includes a containment chamber which includes no moving parts. A compressible gas traverses through four distinct sections of the containment chamber to allow for energy conversion based on the Stirling cycle. The first section performs constant volume heating of the medium, the second section performs isothermal expansion of the medium, the third section performs constant volume cooling of the medium, and the fourth section performs isothermal compression of the medium. Electrical conductors installed within the containment chamber and magnetic field placed adjacent to the electric conductors within the containment chamber will extract electrical energy from the moving compressed ionized gas (CIG) using the principle of magneto-hydrodynamics.

Abstract: The present invention provides a piston-free Stirling cycle engine by incorporating the operation of a Stirling cycle within a rotary engine. The engine consists of a rotor located within a housing. The rotor is circular in shape and has chambers extending into the rotor and positioned around the periphery of the rotor. The rotor is connected to a driver and resides within the housing. A blade extends from each chamber and contacts an inner surface of the housing. Compartments are formed between adjacent extended blades and contain gas. The housing is of a unique shape consisting of four sections having different arcs. A first quarter section and a second quarter section have distinct radii lengths and a common center. The common center is the point about which the rotor rotates. A third quarter section and a fourth quarter section, positioned between the first and second quarter sections, are each connected on opposite sides of the housing and have distinct centers and identical radii lengths.
