We haven’t figured that out yet. Probably they have, and that probably came from their research into fusion power. All the ideas for getting energy out of controlled fusion are concerned with using a magnetic field to contain a mass of high-energy plasma—in principle the same thing we’re trying to do with the free electrons. Most of the basic research in that field comes from Russia, sir. They’re ahead of us because they’ve spent more time and money in the most important place.”
