Scientists have reproduced last year's nuclear fusion breakthrough
to the process that results in stars being able to emit light and heat. The scientists used a laser aimed at fuel to combine two light atoms into a denser one. This releases a great deal of energy. The process is said to have a lot of potential as a source of sustainable, low-carbon energy that could help combat climate change.
In the initial experiment in December, the laser delivered 2.05 megajoules to the target. The scientists achieved fusion ignition by generating 3.15 megajoules of energy output. That's a net yield of around 1.1 megajoules, which is equivalent to 0.31kWh — enough energy to power a 50-watt LED TV for six hours.
It's not yet clear exactly how much of a net energy yield was obtained from the latest successful experiment, which was carried out on July 30th.
