Waste heat thermoelectric generator with auxiliary burner

A thermoelectric generator for producing electric power from waste heat said generator comprising:

• A) a plurality of thermoelectric sub units positioned so as to create a plenum into which the waste heat in the form of a hot media is directed each of plurality of thermoelectric sub units being comprised of:
• 1) a finned hot media duct defining a finned duct through which passes a portion of the hot media exiting the plenum,
• 2) a heat sink,
• 3) a plurality of thermoelectric modules sandwiched between the finned hot media duct and the heat sink,
• 4) a compression element adapted to keep the duct, modules and heat sink in compression
• 5) a hot media exhaust duct adapted to receive exhaust from the finned hot media duct,
• B) an auxiliary burner-blower unit adapted to force hot media into the plenum said burner-blower unit comprising:
• 1) a blower element and
• 2) a burner element.
• C) a generator control means adapted to control the operation of the thermoelectric generator utilizing the auxiliary burner-blower unit to permit electric power generation when the waste heat is not available.
