Generating more energy from a fusion reaction than goes into the fusion plant to heat fuel to temperatures of more than 100 million Celsius has eluded scientists for decades.
Fusion occurs when the nuclei of two light atoms such as hydrogen, heated to extreme temperatures, fuse into one heavier nucleus releasing vast amounts of energy. This is an interesting move, which hopefully signals there is a reality check going on about the efficiency and practicalities associated with solar power and wind farms.
This discovery is one of several major developments over the past year or so that is shaping nuclear fusion technology into a stronger potential candidate for fossil fuel-free energy.
