Nuclear Fusion Reactions Mark a ‘Milestone’

Nuclear Fusion Reactions Mark a 'Milestone'from latimes.com: It took 192 lasers and a building big enough to contain three football fields, but physicists have finally produced a pair of nuclear fusion reactions that created more energy than was in the fuel to start with. The reactions lasted less than a billionth of a second, and they released only a few thousand joules — enough to power a 100-watt light bulb for less than three minutes. But it marks the first time scientists have been able to harness the power of stars here on Earth. "This is really an important milestone," said Warren Mori, a plasma physicist at UCLA who was not involved in the effort. The experiment, conducted at Lawrence Livermore National Laboratory in the Bay Area, is still a very long way from "ignition," the point at which the reaction generates more energy than was required to kick it off with lasers. Scientists agree that significant hurdles remain before that goal can be reached.
