General Fusion is a small company trying to solve a big problem. Our team of 65 (physicists, engineers and technologists) is working on proving that our approach to fusion is the quickest and most practical. We’ve got quite a few talented, smart people here, but we know that there are many talented, smart people elsewhere.

What if fusion became commercial? Nuclear fusion, says Stephen Hawking, could “provide an inexhaustible supply of energy, without pollution or global warming”. The technology’s promises are many, but how would the arrival of commercial fusion affect the design of our energy system?

Traditionally, fusion energy research has meant huge efforts like the $20 billion multinational ITER project and $3.5 billion National Ignition Facility. But that may be changing. In unassuming industrial units across North America, Europe, and elsewhere, small teams of scientists and engineers supported partly or entirely by private finance are working out novel approaches to fusion. Their goal: to design financially viable power reactors simpler and cheaper than the government-funded behemoths and to build them faster. Some of the new technologies look bizarre, but venture capitalists are convinced that each holds at least a slim chance of an enormous payoff.
