An important step on the way to tame fusion power has been taken by researchers in the U.S..
In a series of experiments, they have managed to get more energy from a fusion reaction than they brought.
- It is clearly a breakthrough, says Torbjörn Hellsten, professor of theoretical plasma physics at the University of Technology (KTH) in Stockholm.
experiments in the study, reported in the journal Nature, was conducted at an enormous new facility at Lawrence Livermore National Laboratory in California. The system has been targeted 192 laser beams into a tiny, centimeter large capsule containing small amounts of deuterium and tritium, the two elements of fusion fuel.
rays have met the fuel has become extremely hot, and in the process has managed to produce twice as much energy as was originally brought.
- Results are very laudable, said Hellsten.
Ultimately, the aim is to achieve an ignition of fuel that can make the process self-sustaining. But there is a way to go.
