Thermal Acoustic Resonator by Fellows Research Group, Inc.
Uses sound waves to convert waste heat directly into
useable electricity. Working prototype; video; patent. Can be
printed on microchip. Seeking licensees, developer partners, venture
Quoting from: http://www.io.com/~frg/
This tiny MEMS thermoacoustic generator converts heat into electricity. The
source of heat can be solar radiation, combustible fuel, even body heat. It
requires no maintenance and is cost competitive with all existing power
The MEMS-TAR is manufactured using the same equipment and processes used in
the manufacture of computer chips. It is packaged in single discrete units,
and in integrated panel arrays. Power conditioning circuitry is built right
into the chip.
- Telecommunications satellite power and space power applications.
- Commercial power generation; Energy recovery (co-generation).
- Solar electric and air-conditioning systems for individual homes,
businesses and industry.
- Biomedical prosthetics and artificial organs that operate from body
- Alarms, GPS locator beacons and physiological data transmitters.
- Sensors and controls
- Hundreds of consumer appliances and novelty items.

This is an excellent application of conventional science. It has
tremendous potential for cheaply utilizing low temperature heat. It is
Carnot-limited, but the device is simple and cheap to make and can produce
electricity from heat sources that usually are ignored. It is probably a
Stirling cycle. Piston Stirlings are usually somewhat high tech and
costly. Thermoacoustics has the potential to be far simpler and cheaper,
and these people seem to have a good idea.
