SolarSpace licensed NASA’s Thermal Recovery Energy Efficient System (TREES) and signed Space Act Agreement with NASA.

Designed for harsh environments with very little or no service, NASA Thermal Recovery Energy Efficient System (TREES) converts Heat into Sound Waves, and Sound Waves into Electric Power or Cooling with unprecedented efficiencies. The heat generated at the focal point produces a high-intensity acoustic wave, created from the temperature gradient between the hot and cold heat exchangers. This acoustic wave energy propagates through thermoacoustic power tubes, where it can be used for cooling or converted to electric power via a linear alternator. This technology has no hot moving parts, plumbing, or wiring and is therefore virtually maintenance-free.
