Old mines leave behind a a pressing problem: Huge holes that make the landscape look like a chunk of swiss cheese. But in Germany, some scientists and city planners are turning these into lakes. The largest one will be the biggest artificial lake in Germany when it's done, with a shoreline of 26 kilometers or about 16 miles all around. But it's not as easy as simply filling the holes with water. It takes a LOT of research to get this science right. Interested in more environmental stories? Email us at shortwave@npr.org.

  • Hey, shortwavers.

  • Emily Kwong here, and I am joined by Planet Money producer Willa Rubin.

  • Willa, hey, what's up?

  • Hey, Emily.

  • Hey, Shortwave.

  • I come to you with a story.

  • All right, let's hear it.

  • So about two hours southeast of Berlin, there's a city called Kotbas.

  • It's pretty small.

  • About 100,000 people live there.

  • For context, this is in eastern Germany, near the Polish border.

  • And so historically, this part of Germany had a lot of lignite mining.

  • This is a fossil fuel that is dark brown.

  • It's soft, kind of like an intermediate between hard coal and petroleum coke.

  • Oh, interesting.
