Engineering State v. Lawyerly Society (00:53:12)
This week on Decouple, I sit down with Dan Wang, a research fellow at Stanford’s Hoover History Lab and author of "Breakneck: China’s Quest to Engineer the Future." We trace how China became an “engin...
Where Is Nature Going? (00:54:59)
This week, we zoom out to the broader intellectual themes that shaped Decouple’s origins five years ago. I’m joined by Jesse Ausubel, a visionary in sustainability and biodiversity research and the Di...
Handling the Heat (01:10:08)
Process heat accounts for two-thirds of industrial emissions. Yet talk of decarbonization often misses the engineering realities that separate viable solutions from expensive dead ends. To understand ...
Nuclear Meme Stocks (01:06:42)
Nuclear has entered its meme stock moment. Last week, Oklo hit a market capitalization of $20.7 billion—more than established nuclear giants BWXT, Curtiss-Wright, and AtkinsRéalis—despite having zero ...
