The race to build a commercial fusion reactor hots up
An old joke about nuclear fusion—that it is 30 years away and always will be—is so well-known that The Economist’s science editor forbids correspondents from repeating it. No one doubts sustained fusion is possible in principle. It powers every star in the universe. Making it work on Earth, though, has proved harder. (The Economist)
