on 30 July that produced a higher energy yield than in December, a Lawrence Livermore spokesman said.The experiment produced more energy from fusion than the laser energy used to drive it That experiment briefly achieved what’s known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to the target, the US energy department said. In other words, it produced more energy from fusion than the laser energy used to drive it, the department said.
