Solid-oxide fuel cells can generate electricity using a range of readily available fuels. But because they run very hot–often above 1,000 ºC–they typically require insulation that makes them bulky. A new version employs an insulation technique that keeps the finished device as small as a pack of playing cards. The gadget, which could help keep electronic devices humming on long flights or hikes, runs on cheap butane cartridges; one cartridge packs enough power to recharge a smart phone 20 times. Swap out the cartridge, and it’s ready for 20 more charges. The device is scheduled to go on sale next year.

The record for high-temperature superconductivity has been smashed again
Chemists found a material that can display superconducting behavior at a temperature warmer than it currently is at the North Pole. The work brings room-temperature superconductivity tantalizingly close.
Climate change’s highest cost: Overheated employees too miserable to work
The US economy could lose $221 billion annually by 2090 as people stop working as much or as hard.
Cutting emissions could prevent tens of thousands of heat deaths annually
And that’s just in the United States.
