Air conditioners and refrigerators quietly eat a huge share of the world's electricity, and the gases inside many of them trap heat in the atmosphere. A team at the Hong Kong University of Science and Technology (HKUST) now reports a step toward a different kind of cooling: a solid metal that gets cold when it is squeezed, built in a way that is cheap, fast to make and tough enough to run for more than 100 million cycles.
The work, published in the journal Science and described in an HKUST pres...
