It all starts with a single laser, which is split into 48 separate beams. The beams are then redirected using mirrors into amplifiers—previously pumped by a total of 7,680 Xenon flash lamps— and, after four bounces, they are further split into 192 rays through all the facility—which is the size of three football fields. As they travel through those endless tubes they will be amplified again at an exponential rate.
The result: from a tiny 1/billionth of a joule laser, the scientists at the National Ignition Facility will end up with rays "a foot on the their side" with a combined "1.8 million joules of ultraviolet energy", 1,000 times the energy of all the power plants in the United States combined. That's five trillion watts (and as any numbnuts know, a trillion is more than a million.)
The lasers will then compress the frozen hydrogen fuel cell pictured here, which will be enclosed in a gold-plated cylinder called the hohlraum. The hohlraum—which was probably brought through a Stargate— is located inside the 32.8-foot-diameter ignition chamber, and it will transforms the lasers into extremely intense X-rays, compressing the hydrogen at one hundred billion atmospheres in just 1/1,000,000 of a second.
This will trigger a controlled nuclear fusion reaction that will create a small star, hopefully generating more power than the energy used to fire the laser and contain the intense heat inside the chamber.
All this in theory. The questions is:
