The tipping point for nuclear fusion is ignition, the moment when the lasers release the same amount of energy that is required to power them.
But that goal has remained elusive.
If it was easy, we would have done it 50 years ago, said Doug Eddy, a senior nuclear security agency operations manager working on the project.
