WASTE HEAT CAPTURE USING TAIL CONE OF A GAS TURBINE ENGINE

A waste heat capture system that can be used with at least a gas turbine engine (200). The system includes: an air scoop (202) connected to a first component, the air scoop (202) configured to direct air from a first duct to an interior compartment of the first component; a second duct along an exterior of the first component; and a thermoelectric material (302) connected to an interior surface of the first component. The interior compartment of the first component is on a first side of the thermoelectric material (302) and the exterior of the first component is on a second side of the thermoelectric material (302). The first duct is configured to receive air having a first temperature range, and the second duct is configured to receive air having a second temperature range, wherein the second temperature range is an order of magnitude higher than the first temperature range.
