The promise of abundant, clean energy powered by nuclear fusion is one big step closer thanks to a new experiment. The results are a historic scientific milestone, but energy production remains a ways off.
In January 2022, the JET fusion experiment produced more power over a longer period of time than any past attempt. Two physicists explain the engineering advancements that made the result possible.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
