Bob Mumgaard, CEO of Commonwealth Fusion Systems, explains at the All-In Summit why nuclear fusion technology is commercially viable today compared to previous decades.
“We have predictive capability of these machines the same way that we have predictive capability of, like, how to build a plane, right?”

Mumgaard: CFS expects net energy fusion gain by early 2026
“And we'll start to assemble that machine later this year. And turn it on in this sort of, twenty-twenty-five time frame and get to Q greater than one, more power out than N for the first time probably early twenty-twenty-six.”

Mumgaard: Fusion capital requirements are an order of magnitude less than renewables
“Because you're just building capital, and there's no operating cost, there's no fuel, and the capital you're building is an order of magnitude less stuff than, say, renewable.”

Insight
Mumgaard: Fusion power price depends on learning rates, not architecture
“Because that price of power, it's not so much architecture dependent, it's learning rate dependent, right? At the end of the day, the amount of stuff in these things is all about the same. And so, the faster you get there, the better your cycles are, the lower…”
