What's Your Problem?

Every week on What’s Your Problem, entrepreneurs and engineers talk about the future they’re trying to build – and the problems they have to solve to get there.

How do you take a drone delivery service you’ve built in Rwanda and make it work in North Carolina? How do you convince people to buy a house on the Internet? How do you sell thousands of dog ramps to weiner dogs all across America when a pandemic breaks the global supply chain? 

Hosted by former Planet Money host Jacob Goldstein, What’s Your Problem helps listeners understand the problems really smart people are trying to solve right now.

Drilled, a new addition to the Pushkin network, is a true-crime climate change podcast exposing how corporate corruption and political operatives built decades of climate denial and delay. Award-winning investigative journalist Amy Westervelt unravels evidence of deception, disinformation, and the power structures keeping real climate solutions out of reach. Her new season, Carbon Cowboys, traces how the ethanol kingpin of Iowa became the king of corn in Brazil. In September 2025, a group of Brazilian ministers trekked all the way to chilly North Dakota to see a presentation on a new type of clean energy project, one that promised to help them deliver Brazilian President Lula’s dream of turning Brazil into "the Saudi Arabia of sustainable aviation fuels." It was the latest in a string of projects from Midwest Republican kingmaker Bruce Rastetter, whose investments in Brazil might just transform him into a global carbon czar, even as his Summit pipeline carbon project faces fierce opposition from Iowa to North Dakota. The problem? It all requires loads of land and none of it does a thing about climate change.

Rob Meyerson is the co-founder and CEO of Interlune. Rob's problem is this: How do you help build an economy on the moon? Eventually, Rob hopes Interlune will help build a moon base. For now, he is focused on bringing a gas called helium-3 back from the moon to sell on earth. 

Earlier in his career, Rob was the president of Blue Origin, the rocket company founded by Jeff Bezos.

In this episode, Rob explains: 
 Why reusable rockets are only the first step for going back to the moon
What it's going to take to actually manufacture things in space
How to build a business by sifting through moon dirt
How nuclear fusion and quantum computing could rely on mining the moon

Building a Business on the Moon

Aaron Edsinger left his job as director of robotics at Google to start a company called Hello Robot. Aaron’s problem is this: How do you build an affordable robot that people can use to solve real problems at home? The result is a robot that looks nothing like a person. In fact, it’s closer to a Roomba with an arm.

In this episode, Aaron explains: 
 Why home robots have barely progressed since the Roomba
Why simpler robots can be more useful than complex humanoids 
 Why the physical world is so much harder for AI than language
How robot safety is fundamentally a physics problem
