the key part of this reaction only lasts for five seconds and only generated enough powerfor 60 kettles, but it is an important proof that scientists are on the right track. there is still lots of work to do, and athina kappatou is one of a new generation of physicists who plan to do it at a scaled—up version version of the uk reactor being built here version of the uk reactor being built here in the south of france. do you think you'll see commercial fusion in your lifetime? version of the uk reactor being built here do you think you'll see commercial fusion in your lifetime? yes, i am confident — i want to believe in it. so, answer me this, why is it taking so long? it is hard, it is really hard, very complex, but it's worth it and we just have to do it for the future. fusion energy is carbon—free, but it is not going to be ready in time to get us out of the climate crisis. that shouldn't stop this research, say supporters. the enormous promise fusion
