Here's today's feel-good story:

MIT scientists have developed a portable desalination unit that weighs less than 10 kilograms and can remove particles and salts from seawater.

The device is suitcase-sized and can be powered with less energy than a cell phone charger. It is powered by a small solar panel, and the quality of water exceeds that of the World Health Organization quality standards.

“This is really the culmination of a 10-year journey that I and my group have been on. We worked for years on the physics behind individual desalination processes, but pushing all those advances into a box, building a system, and demonstrating it in the ocean, that was a really meaningful and rewarding experience for me,” says senior author and professor of electrical engineering and computer science and of biological engineering, Jongyoon Han
