Maybe by 2050 they will have moved beyond the prototype stage, if a protype is even working (in Japan) by then. What's being started in France is experimental.

Here's the problem: Who will pay for it? It would cost a lot. For its own industry, the U.S. seems to be moving in the opposite direction. Coal is cheap (and there's plenty of it), and oil-dependent industries won't do anything about it until there is a real crisis.
Bush said that the U.S. would not ratify the Kyoto Protocol, but would come back with something even better. After some time passed, they came back with something ridiculous, and it was soon forgotten.
An environmentalist wrote a compelling article a few months ago about how alternative energy sources will not be able to come close to meeting the world's energy needs any time soon, and the only practical solution is to build a lot more (fission) nuclear power plants, as France has done.
