High Performance Nanoscale Thermoelectric Generator for UAVs

Advancement of thermoelectric (TE) technology has been a major research area for over a century, yet most compositional materials research has not produced TEs with a figure of merit (zT) greater than unity. New methods of enhancing TE efficiency are needed and have been realized through structural alteration of TE materials. Modifying this approach, Mainstream aims to achieve zT Y 4 for high efficiency TE generators. Further refinement of Mainstreams innovative and low-cost approach could lead to even higher zT values and greater efficiencies. In Phase I, Mainstream will test its TE devices at operating temperatures of 135 F and 300 F. Phase II will include further testing at 400 F in a laboratory bench test and perform any needed redesigns. In preparation for transition to military and commercial platforms, Mainstream will also concurrently develop aircraft interfaces and system level integration.
