NOVELTY - The electric power generation system (10) has thermally conductive conformal layer (16) on ceramic liner (14) of hot gas path enclosure to provide conformal mounting surfaces, thermoelectric elements mounted on conformal layer with inner surface of each thermoelectric element adjacent one conformal mounting surface, cooling channels (24) connected to outer surface of thermoelectric elements, and clamp (28) which surrounds and applies clamping force to maintain thermal and physical contact between ceramic liner, conformal layer, thermoelectric elements, and cooling channels.    USE - Electric power generation system for passive conversion of waste heat in hot gas flow path in propulsion system of scram jet or other hypersonic vehicle into electrical energy. Can also be used for rocket based, turbine based or fusion based system.    ADVANTAGE - The electric power generation system surrounds a hot gas path of an energy source to provide passive thermoelectric energy. The ceramic hot face liner is coated with thermally conducting material capable of being shaped to form mounting surfaces that conform to inner surfaces of thermoelectric elements attached to the liner to maximize thermal communication between the thermoelectric elements and the hot face liner. Cooling channels attached to outer surfaces of thermoelectric elements result in thermal gradient across the thermoelectric elements and resulting thermoelectric power generation. Clamps that apply clamping forces to maintain thermal and physical contact between all thermoelectric elements and ceramic liner result in improved power generation.    DETAILED DESCRIPTION - The ceramic liner comprises ceramic matrix composite selected from a group consisting of carbon fiber reinforced silicon carbide (C/SiC), carbon fiber reinforced carbon (C/C), silicon carbide fiber reinforced silicon carbide (SiC/SiC), silicon melt infiltrated silicon carbide reinforced silicon carbide (MI SiC/SiC) and mixtures of composites. The thermally conductive conformal layer comprises silicon. The cooling channels comprise metal channels for carrying fluid coolant. The clamp comprises springs, such as canted coil springs, surrounding the enclosure, putting the components under compression. An INDEPENDENT CLAIM is also included for a method for forming electrical power generation system.
