Engineers turn plastic insulator into heat conductor

02.04.2018 | MIT | news.mit.edu

Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in…

In field tests, device harvests water from desert air

23.03.2018 | MIT | news.mit.edu

Even in the most arid places on Earth, there is some moisture in the air, and a practical way to extract that moisture could be a key to survival in such bone-dry locations. Now, researchers at MIT…
