Scientists have been working to achieve self-sustaining nuclear fusion and energy gain in the laboratory for more than half a century. When the National Ignition Facility (NIF) is completed at Lawrence Livermore National Laboratory (LLNL) in 2009, that long-sought goal will be much closer to realization.
NIF's 192 giant lasers, housed in a ten-story building the size of three football fields, will deliver at least 60 times more energy than any previous laser system. When all of its beams are operational, NIF will focus about two million joules of ultraviolet laser energy on a tiny target in the center of its target chamber – creating conditions similar to those that exist only in the cores of stars and giant planets and inside a nuclear weapon. The resulting fusion reaction will release many times more energy than the laser energy required to initiate the reaction. Experiments conducted on NIF will make significant contributions to national and global security, could lead to practical fusion energy, and will help the nation maintain its leadership in basic science and technology. The project is a national collaboration among government, industry and academia and many industrial partners throughout the nation.
Programs in the NIF & Photon Science Directorate draw extensively on expertise from across LLNL, including the Physical Sciences, Engineering, Computation and Chemistry, Materials, Earth, and Life Sciences directorates. This goal is a scientific Grand Challenge that only a national laboratory such as Lawrence Livermore can accomplish.

NIF is the model to show how to get your company out of bankruptcy. Just have everyone else taxed to support you.

Well you may as well come by May 29th and 30th to see what was built. It's the last time you'll ever get to see the target chamber before she goes hot. Know of any other project on site that's made any accomplishments in the last few years that may in fact keep the gates open and people employed?
So I want to know why the first firing of all 196 beams was at 2:00 am last Thursday when no one was around. Were they afraid it might go boom and wanted to limit the potential for wounded bystanders?
Who knows what this proposed NIF amphitheater is about. Heard they want $5M to do more landscaping for NIF. Didn't they think the bronze lettering on the granite boulders was classy enough?
