Catalytic converters are disappearing. If you’ve had yours stolen, you know that rare earth metals are valuable. But these metals are in great demand for things other than converters, such as batteries for electric cars, wind farms and solar panels.

We need rare earth metals to combat climate change, but where to get them? Could we find substitutes?

One activity that could be in our future: Deep sea mining. But it’s controversial. Can one company’s plan to mitigate environmental harm help?

Guests:

Chris Leighton - Distinguished University Teaching Professor, Editor, Physical Review Materials, Dept. of Chemical Engineering and Materials Science, University of Minnesota
