Desalination with solar power via sciencealert2014
By inexpensively turning salt water into drinking water using sustainable solar power, a team from MIT in the US has not only come up with a portable desalination system for use anywhere in the world that needs it, but it’s… won the 2015 Desal Prize – a competition run by USAID to encourage better solutions to water shortages in developing countries.
In order to win the $140,000 prize, entries had to demonstrate how their invention not only works well, but is cost-effective, environmentally sustainable, and energy efficient. And the MIT researchers teamed up with US-based manufacturing company, Jain Irrigation Systems, to do just that.
The team’s invention works by using solar panels to charge a cache of batteries that power an electrodialysis machine that removes salt from the water and makes it perfectly drinkable
