And they will succeed around 1% of the time. In fusion research, pessimism is realism. Especially in laser powered fusion. This experiment is producing 2.5 MJ of output for 500 MJ of input. Roughly once a day. After decades of basic research. It's a scientific breakthrough in the sense that the rocks are now being banged together hard enough to make sparks. And a little more is known about rock banging than was known ten years ago. But it's clearly not going to be producing power on a commercial scale any time soon.
