The promise of natural gas, shale oil, renewable energy and conventional nuclear power all pale in comparison to the promise of clean, potentially abundant fusion power — and that’s attracting increasing attention from science-savvy entrepreneurs.

Almost two dozen private ventures are trying to crack the fusion challenge, backed by a combined total of more than a billion dollars of private investment, said Chris Mowry, the CEO of Vancouver, B.C.-based General Fusion. (One Seattle venture, CTFusion, is currently looking for lab space.)

Mowry drew parallels to the enthusiasm sparked by SpaceX in the launch industry.

“I feel like this is the SpaceX moment for fusion,” he said today at a Seattle breakfast session on commercial fusion ventures, organized by the CleanTech Alliance.

But when you ask about the time frame for commercializing fusion power, the answers get squishier. And there’s good reason for that.

On one hand, there’s the old joke that fusion is the energy solution of the future, and always will be. On the other hand, it’s tempting for business entrepreneurs to predict that their systems will start showing a net energy gain within, say, three years.

That’s basically what David Kirtley, the CEO of Redmond, Wash.-based Helion Energy, told The Wall Street Journal three and a half years ago. “If our physics hold, we hope to reach that goal …read more
