Storing wind as gravity, and well-digging donkeys

Contributing Correspondent Cathleen O’Grady joins host Sarah Crespi to talk about a company that stores renewable energy by hoisting large objects in massive “gravity batteries.”

Also on this week’s show, Erick Lundgren, a postdoctoral researcher at Aarhus University, talks about how water from wells dug by wild horses and feral donkeys provides a buffer to all different kinds of animals and plants during the driest times in the Sonora and Mojave deserts.

This week’s episode was produced with help from Podigy.
