The project will take 10 years and cost $6 billion to complete, with the goal of producing fusion electricity by the middle of the century. There´s just one holdup. As we went to press, the international collaboration backing ITER-China, the European Union, Japan, South Korea, Russia and the U.S.-was still arguing over where to build it. For the past year it
has been split between sites in France and Japan (China and Russia favor France; the U.S. and South Korea back Japan), and no amount of negotiation seems able to break
the impasse. It´s an inauspicious start to a
collaborative endeavor second in scope only to the International Space Station.
