While preparing last week’s post, where I explored the lengths we will go to mine rare earth elements, I came across a TED talk I’d like to share.
In Our race to find rare earths, from deep sea to the moon, I mentioned the possibility of using nanomaterials to recover precious minerals from seawater.
Research engineer Damian Palin has been working on a similar idea, but better: the ultimate win-win situation even the greenest mining opponent couldn’t object to! He’s developing a way to use bacteria to biologically “mine” minerals from water — specifically, out of the brine left over from the desalinization process. (more…)
