Aerospace giant Lockheed Martin’s announcement this week that it could make small-scale nuclear fusion power a reality in the next decade has understandably generated excitement in the media. Physicists, however, aren’t getting their hopes up just yet.

I recently returned from the International Atomic Energy Agency’s Fusion Energy Conference in St Petersburg, Russia, the world’s leading conference on the development of fusion power. There was no announcement of research by Lockheed Martin, and the company did not field any scientists to report on their claims.

Lockheed Martin claims that its technology development offshoot, Skunk Works, is working on a new compact fusion reactor that can be developed and deployed in as little as ten years. The only technical details it provided are that it is a “high beta” device (meaning that it produces a high plasma pressure for a relatively weak magnetic field pressure), and that it is sufficiently small to be able to power flight and vehicles.

This isn’t enough information to substantiate a credible program of research into the development of fusion power, or a credible claim for the delivery of a revolutionary power source in the next decade.
