“The goal is to achieve ignition – a point at which the energy generated by the fusion process exceeds the total energy input.”<p>“The experiment, conducted on 8 August, fell just short of that mark; the input from the lasers was 1.9 megajoules [vs 1.3MJ output]. But it's still tremendously exciting, because according to the team's measurements, the fuel capsule absorbed over five times less energy than it generated in the fusion process.”
