When you’re camping in the great outdoors, powering essential devices like phones, radios, or portable lights is a challenge.

A group of researchers led by the Chinese Academy of Sciences (CAS) has developed a heat-driven thermoacoustic refrigerator/heat pump (HDTAR/HDTAHP) for high heating-temperature operation.

But have you seen an engine with only one moving part, out of four in total? In the thermoacoustic engine, the power piston is the only part in motion. [YTEngineer] has built a very simple ...

The work focuses on using the excess heat produced by stoves to create a thermoacoustic engine, which converts thermal energy into acoustic energy. This acoustic energy can then be transformed into ...

A research group at Technion – Israel Institute of Technology has developed a novel phase-change thermoacoustic heat pump (PTHP) concept for residential and industrial heat pumping.

The concept is called thermoacoustic refrigeration -- using sound waves to cool something. The technology offers several advantages over conventional cooling systems, says a Purdue University engineer ...

Research by Lixian Guo at the University of Canterbury may make it possible to keep electronic devices powered with another piece of equipment you’re likely to bring with you while exploring the great ...

While camping is a great opportunity to unplug and connect with nature, it's hard not to rely on some sort of technology—cellphones, radios, lanterns, and portable chargers are all useful tools to ...
