Physical Optics Corporation — Department of Defense SBIR Phase I: To address the Navy"s need for high-efficiency thermoelectric power generators, Physi

Description

To address the Navy"s need for high-efficiency thermoelectric power generators, Physical Optics Corporation (POC) proposes to develop a new Self-Contained Heat Exchanging Thermoelectric Energy Source (SCHETES). This proposed device is based on electrically conductive silicon-nanostructures embedded within a high-temperature matrix for high-efficiency conversion of heat to electrical energy (expected ZT of>1.5) within a high-efficiency heat exchanger. The innovation in silicon-nanostructures will enable the system to provide up to 700 W of electrical energy in a package 10 in. x 10 in. x 5 in., weighing only 7.65 lb, which is capable of burning all types of logistic fuels and handling the high temperatures by using materials with high melting points. As a result, SCHETES offers a large amount of electrical energy in a small package with low weight and provides selectable output voltages of 12 V or 24 V, which directly address the Navy"s requirements for supplemental power for weapon systems. In Phase I, POC will demonstrate the feasibility of SCHETES by simulation and design, as well as a Phase I proof-of-concept prototype. In Phase II, POC"s plans include prototype development and performance validation, with a final report incorporating analysis and recommendations for transition to Phase III.
