The generation of electrical power from thermal sources has wide direct applications for NASA. Some of these for space missions include supplemental/backup power for instrument and life support on manned space vehicles; non-manned space vehicles to supplement main power and instrument batteries; main and supplemental power source for planetary exploration vehicles; main and supplemental power source for satellites; supplemental/backup power for instrument and life support on ISS; and supplemental/backup power for instrumentation on sounding rockets and balloons. Indirect applications include supplement/eliminate batteries in experimental apparatus at NASA R&D Centers; harvesting energy from heat sources such as pump house engines; remove the passive heat load generated by the ambient environment and active devices in order to stabilize the temperature of sensitive components; and using thermoelectrics to drive component temperatures far lower than normal to the sensitivity of detectors, CCD, thermal imaging cameras, solid state lasers and other sensors.
The generation of electrical power has numerous applications for DOD including fatigues to minimize the battery weight; heat from artillery barrels to minimize the battery weight for electronic gun controls; vehicles to minimize battery requirements for electronics; missile launchers to minimize batteries for launchers and guidance and control systems; nuclear, biological, and chemical defense systems to minimize battery weight; micro and full sized submarines to minimize battery requirements; surface ships to minimize battery and power generation requirements; aircraft to minimize batteries for electronics and life support; unmanned aerial vehicles to minimize battery requirements and weight; and aircraft to minimize batteries for electronics and life support. Applications to the civilian market are similar to DOD, to include clothing; cell phone holsters; tents; backpacks; vehicles, including the passenger compartment; and power generation during emergencies.
