[QUOTE="James Snover, post: 16854350, member: 67454"] As per usual, I forgot the link: [URL unfurl="true"]https://www.llnl.gov/news/national-ignition-facility-achieves-fusion-ignition[/URL] They did bend the truth a bit, there. The lasers are something less than 75% efficient. But of the energy sent to the fuel, i.e., the energy pumped into the lasers that was converted to laser photons, more energy did come out. If we had more efficient lasers, the energy required to create the reaction still would have been more than the 2.05 Mega Joules delivered, because there are always losses in energy conversion. Kind of like how it takes a lot more energy to boil water with electricity, than it does to boil water with gas. But to get the water to boil either way, regardless of how efficient, or not, the method used, it still takes a certain irreducible amount of energy to boil the water. It took about 20 years just to develop the lasers for this. It took another ten to figure out how to refine it to the right wavelengths, focus it, control it, time and synchronize it, etc. [/QUOTE]
