A nuclear fusion world record has been set in the US, marking another step on the long road towards the unlocking of limitless clean energy. A team at the Massachusetts Institute of Technology (MIT) created the highest plasma pressure ever recorded, using its Alcator C-Mod tokamak reactor. High pressures and extreme temperatures are vital in forcing atoms together to release huge amounts of energy. Nuclear fusion powers the sun and has long been touted as the ultimate solution to powering the world while halting climate change. But, as fusion sceptics often say, the reality has stubbornly remained a dec ade or two away for many years. Now MIT scientists have increased the record plasma pressure to more than two atmospheres, a 16% increase on the previous record set in 2005, at a temperature of 35 million C and lasting for two seconds. The breakthrough was presented at the International Atomic Energy Agency’s fusion summit in Japan on Monday.
