To everyone whining about the lasers: who cares? It's an engineering problem, and there are already clear solutions and paths forward. Efficiency of the plant isn't what's being discussed in the announcement. Plant efficiency is an entirely separate problem that we already know about. The exciting thing is that they've shown a fusion reaction in lab conditions which produces more energy than it takes to start it. Yes, the gain is small. It's nearly irrelevant to the amount of energy used to run the reactor, yes. But it clearly shows that what we're trying to do is possible, and we've identified one mechanism that can initiate these reactions. It's exciting. This is a great result that shows the science is progressing and beginning to finally show results.
