Correspondence Address: Jon Murray Schroeder An improved torus multi-element semiconductor thermo Suite # 148-323 electric hybrid utilizes a make-before-break high frequency 100 E_ Whitestone B]vd_ switching output component to provide nominal alternating Cedar Park, TX 78613 ([15) current voltage outputs. Overall ef?ciency of heat conver

sion is improved by coupling a chiller to the thermoelectric (21) Appl, No,: 10/154,757 generator Where exhaust heat produces chilled liquid or air

that is conveyed to the cold side of the thermoelectric (22) Filed: May 23, 2002 device.
