🌊 Fusion, and Other Fusion-Level Bets

Why the dream of limitless clean energy is still alive, and why the real question is cost, not physics.

We’re joined by Andy Lubershane, Partner at Energy Impact Partners and author of Steel For Fuel.

In this episode, we dive into nuclear fusion, the most ambitious energy technology on the table, and unpack what it really takes to turn a scientific breakthrough into a commercially viable power source.

In our conversation, we covered:

→ Why fusion has been “20 years away” for the last 60 to 80 years

→ The physics behind the challenge: hot enough, dense enough, for long enough

→ What Q = 1 really means — and why the headlines often get ahead of reality

→ Why Andy still believes some companies may hit real net energy gain soon

→ The difference between a scientific milestone and an investable commercial one

→ Why fusion could be the ultimate energy prize, if it ever becomes affordable

Andy breaks down the famous triple product at the heart of fusion: you need to create conditions that are extraordinarily hot, incredibly dense, and stable for long enough to generate more energy than you put in. That is easy to describe. It is brutally hard to do.

We also unpack the gap between lab success and market success. A fusion reaction can be scientifically impressive and still be economically irrelevant. That distinction matters. A lot.

And then there is the upside. If fusion works at scale, especially in a form that uses abundant fuel and avoids the safety, waste, and proliferation issues of fission, it starts to look like one of the biggest energy breakthroughs humanity could hope for.
