Lots of big machines to make a tiny Sun

The Big Picture has a selection of photos of the National Ignition Facility which I’ve written about previously.

“Creating a miniature star on Earth” is the goal of the National Ignition Facility (NIF), home to the world’s largest and highest-energy laser in Livermore, California. On September 29th, 2010, the NIF completed its first integrated ignition experiment, where it focused its 192 lasers on a small cylinder housing a tiny frozen capsule containing hydrogen fuel, briefly bombarding it with 1 megajoule of laser energy. The experiment was the latest in a series of tests leading to a hoped-for “ignition”, where the nuclei of the atoms of the fuel inside the target capsule are made to fuse together releasing tremendous energy — potentially more energy than was put in to start the initial reaction, becoming a valuable power source.

The NIF and the LHC are this generation’s Apollo program.
