NEW YORK (AP) — Scientists say that they've taken a key step toward harnessing nuclear fusion as a new way to generate power, an idea that has been pursued for decades.
The amount of energy they got out of their experimental apparatus was only about one percent of what they put into it, so they are still far from their goal.
But the hydrogen fuel put out more energy than it had absorbed. And scientists saw evidence that energy from the fusion reaction was going back into the remaining fuel. That's an encouraging sign for future improvements.
The results were reported Wednesday in the journal Nature.
