Investors are pouring billions of dollars into nuclear fusion companies. The dream: transform human civilization (and power AI data centers) by providing cheap, abundant energy. But nobody’s figured out how to make it work yet.

What will it take to make fusion work at scale – and how will the world be different if it does? To answer this question, Jacob recently hosted a conversation at SXSW between Greg Piefer of SHINE Technologies, Melanie Windridge of Fusion Energy Insights, and Luke Ward of investment firm Baillie Gifford.

In this episode, the guests explain:

• The incredible promise of fusion
• What it will take to realize that promise
• How the AI boom and the demand for power is shaping the fusion industry
• Why having a ton of money flowing into the field is not necessarily a good thing

Rare earth elements are inside pretty much everything with an on-off switch: Phones, laptops, cars. Even missiles. And China controls the world’s supply of components made from rare earths.

David Abraham is the author of the book “The Elements of Power: Gadgets, Guns, and the Struggle for a Sustainable Future in the Rare Metal Age.” David’s problem is this: What should the US do about China's chokehold on the rare earth supply chain?

According to Abraham, the current US strategy could wind up costing billions of dollars without solving the problem. And he has a big idea for what we should do instead.

In this episode, David explains:

• How China quietly built a monopoly on rare earth materials
• Why the 2010 Japan crisis was a preview of today's trade war
• China’s export restriction strategy
• Why the problem goes deeper than billions in spending can solve
• Why electric vehicles are the key to reinvigorating the U.S. rare earth industry

After bacteria were discovered, it took scientists 200 years to figure out that they cause disease. If scientists had made the link sooner, hundreds of millions of lives could have been saved.

In his recent book So Very Small, Tom Levenson, a professor of science writing at MIT, tells the amazing story of germ theory, and argues that our worldview can prevent us from seeing what is right in front of us – even when lives are at stake.
