WikimediaCommons Scientists set a new record for energy produced by nuclear fusion. The Joint European Torus facility in Oxford, England, sustained a fusion reaction for five seconds, generating 69 megajoules, “enough to boil about 70 kettles,” according to the Financial Times. The experiment still consumed far more energy than it produced, but it’s another step along the road to viable fusion energy. JET will be decommissioned this year, replaced by a newer, larger U.K.-based program as well as, in France, the enormous ITER, which will be the world’s largest fusion reactor at its much-delayed opening. Its developers hope it will produce its first plasma next year, and full fusion within a decade of that. |
