European scientists have taken a significant step closer to mastering a technology that could allow them to one day harness nuclear fusion, providing a clean and almost limitless source of energy, British officials said Wednesday.
Researchers at the Joint European Torus experiment near Oxford managed to produce a record amount of heat energy over a five-second period, which was the duration of the experiment, the U.K. Atomic Energy Authority said.
“If we can maintain fusion for five seconds, we can do it for five minutes and then five hours as we scale up our operations in future machines,” said Tony Donne, program manager for EUROfusion. “This is a big moment for every one of us and the entire fusion community.”
Ian Chapman, CEO of the U.K. Atomic Energy Authority, said the results were a “huge step closer to conquering one of the biggest scientific and engineering challenges of them all.”
Researchers around the world have long been working on nuclear fusion technology, trying different approaches. The ultimate goal is to generate power the way the sun generates heat, by pressing hydrogen atoms so close to each other that they combine into helium, which releases torrents of energy.
