sphere contained a layer of deuterium-tritium fuel that was just 70 microns thick, barely the width of a human hair.

With a precise combination of shocks from the laser beams, the pressure inside the sphere was several times greater than at the center of the sun. It lasted for about a seventh of a billionth of a second, long enough for the fuel inside to start fusing together, Hurricane said.

After two runs of the experiment, the scientists measured the energy output by tracking the energy level of the spare neutrons flying out from the tiny sphere. The first one released 14,400 joules of energy, slightly more than the 12,000 joules contained in the deuterium-tritium fuel to start with. The second run was better: 17,300 joules out for just 9,400President Nelson extends invitation to his 95th birthday celebration
