MIT researchers Steve Dubowsky, Amy Bilton and Leah Kelly have created a solar-powered portable desalination system that could make clean drinking water available in countries that need it most. Using a process called reverse osmosis, the solar panel powers different pumps in the system that then force the seawater through a permeable membrane that filtrates the salt from the water. SmartPlanet shows you a time-lapse video sequence of the process.
