National Ignition Facility Contains World's Most Powerful Laser
The world's most powerful laser that took $5 billion and a decade recently debuted with a special dedicated at the Livermore National Laboratory in California. The laser is housed inside a football field sized building called the National Ignition Facility. The AP says the laser was designed to help ensure the reliability of the nation's aging nuclear weapons but it could also be used one day to create a more efficient energy source. In 2010, NIF will focus the intense energy of 192 giant laser beams on a BB-sized target filled with hydrogen fuel - fusing, or igniting, the hydrogen atoms' nuclei in the world's first controlled thermonuclear reaction.
