The world needs clean water
The world needs clean water, and more and more, we’re pulling it from the oceans, desalinating it, and drinking it. But what to do with the salty brine left behind? In this intriguing short talk, TED Fellow Damian Palin proposes an idea: Mine it for other minerals we need, with the help of some collaborative metal-munching bacteria.
Damian Palin is developing a way to use bacteria to biologically “mine” minerals from water — specifically, out of the brine left over from the desalinization process.
