Rather than splitting atoms, fusion mimics a process that occurs naturally in stars to meld two hydrogen atoms together and produce a helium atom - as well as a whole load of energy.Īchieving fusion requires unimaginable amounts of heat and pressure. One approach to achieving that is to turn the hydrogen into an electrically charged gas, or plasma, which is then controlled in a donut-shaped vacuum chamber. This is done with the help of powerful superconducting magnets such as the 'central solenoid' that General Atomics began shipping from San Diego to France this summer. Scientists say ITER is now 75% complete and they aim to fire up the reactor by early 2026. "Each completion of a major first-of-a-kind component - such as the central solenoid's first module - increases our confidence that we can complete the complex engineering of the full machine,” said ITER's spokesman Laban Coblentz. The ultimate goal is to produce ten times more energy by 2035 than is required to heat up the plasma, thereby proving that fusion technology is viable.Īmong those hoping to beat them to the prize is the team in Massachusetts, which said it has managed to create magnetic field twice that of ITER's with a magnet about 40 times smaller. The scientists from MIT and Commonwealth Fusion Systems said they may have a device ready for everyday use in the early 2030s.
