Well, not quite. The UK had a Nuclear Fusion program waay back in the 50s, but - as we Brits tend to do - gave up on it. We would've been the world leaders in fusion by now, maybe even have a reactor. But, hey, BP.
"The experiment in Greifswald is part of a world-wide effort to harness nuclear fusion, a process in which atoms join at extremely high temperatures and release large amounts of energy that's similar to what occurs inside the sun.
Advocates acknowledge that the technology is probably many decades away, but argue that - once achieved - it could replace fossil fuels and conventional nuclear fission reactors."
And then this happened a couple days later in China: ONE HUNDRED AND NINE SECONDS.
