HIGH EFFICIENCY HEAT GENERATOR

摘要

A method for heating a medium that includes an object having a variable weight (184) is provided. The method comprises (A) placing medium including an object having variable weight (184) into a variable enclosure (182) having adjustable dimensions; (B) initiating a heating process by subjecting the medium including the object to a variable AC electrical field (172); (C) substantially continuously measuring (176) an impedance of medium including the object during the heating process; (D) adjusting dimensions of said variable enclosure to optimize the heating process; (E) adjusting parameters of the variable AC electrical field (174) to optimize the heating process; and (F) controlling (178) the heating process.
