Major Breakthrough on Nuclear Fusion Energy
European scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion - the energy process that powers the stars.
Fusion works on the principle that energy can be released by forcing together atomic nuclei rather than by splitting them, as in the case of the fission reactions that drive existing nuclear power stations.
The fusion announcement is great news but sadly it won't help in our battle to lessen the effects of climate change. There's huge uncertainty about when fusion power will be ready for commercialisation. One estimate suggests maybe 20 years. Then fusion would need to scale up, which would mean a delay of perhaps another few decades.
