What's the deal with closed-loop geothermal?
09/1/2026 | 1h 5min
Conventional geothermal energy is limited to specific hot spots, but “closed-loop” geothermal, by going deeper and confining water to sealed boreholes, promises to work almost anywhere; it amounts to building a giant radiator, deep underground. I’m joined by Jeanine Vany and Mark Fitzgerald of pioneering closed-loop startup Eavor to discuss their newly operational plant in Germany and the many advantages of a system that requires no fracking and consumes no water.

NYC's congestion pricing has been running for a year now. How's it doing?
07/1/2026 | 59min
In this episode, I’m joined by Kate Slevin of the Regional Plan Association to discuss the triumphant first year of congestion pricing in Manhattan. We explore how the program defied its critics by boosting business and pedestrian traffic while reducing gridlock, without evident traffic spillover onto adjacent streets. We also cover the money that’s been raised for public transit and what the future holds for the congestion relief zone. This is a public episode.

What's the real story with Australian rooftop solar?
26/12/2025 | 1h 27min
Why can Australian homeowners get rooftop solar installed in a week or less, for roughly 50 cents a watt, while Californians pay $3.30/w and wait months for interconnection? In this episode, I ask inimitable Australian energy expert Saul Griffith to walk us through the entire process — from quote to interconnection — to pinpoint exactly where the US system is broken and how we could fix it.

The cure for misinformation is not more information or smarter news consumers
19/12/2025 | 1h 10min
The problem of misinformation in the current age, argues political scientist Samuel Bagg, is not that reliably truth-producing institutions and practices don’t exist, but that people have ceased to trust them. Changing that requires something deeper than factchecking or media literacy. It’s a matter of social identity, and solving it will mean reconfiguring the social identity landscape. I talk with Bagg about that daunting conclusion and its implications for democracy. This is a public episode.
