An Encapsulated Magneto Hydro Dynamic drive system that solves the efficiency problem of traditional Magneto Hydrodynamic systems by encapsulating a highly ionizable fluid within a flexible membrane that is surrounded by a rigid tube. The exterior rigid tube is wrapped in electromagnetic coils. When a coil is energized, it attracts the ionized fluid, causing a bulge in the flexible inner sleeve resulting in a constriction of the effective tube diameter. By energizing subsequent electro magnets, this constriction moves to the desired exit end of the propulsion tube. The result is that the environmental fluid is propelled out of the tube with the result of tube acceleration in the direction opposite of the energizing of the electromagnetics. By repeatedly energizing the sequenced electromagnets, propulsion of a body through the fluid is achieved. Whitepaper.
