Boy, that must really rot their socks! The big physics budget cut passed by the US Congress, practically dictated that they must pull out of ITER. Now, China has come in with big bucks.
ITER is a big world fusion project. For a while, Canada thought they could provide a site at Darlington, but France won out. The focus of the project is on the engineering aspects of maintaining a plasma fusion toroid. The project is not designed to be a net provider of energy.
