Fusion Progress

NPR: "Scientists Say Their Giant Laser Has Produced Nuclear Fusion".

One caveat:
Strictly speaking, while more energy came from fusion than went into the hydrogen fuel, only about 1 percent of the laser's energy ever reached the fuel. Useful levels of fusion are still a long way off. "They didn't get more fusion power out than they put in with the laser," says Steve Cowley, the head of a huge fusion experiment in the U.K. called the Joint European Torus, or JET.
