Very cool stuff; about a megajoule’s worth of net positive energy output from a lab fusion experiment at the Lawrence Livermore National Laboratory. We have ignition! Not ready for steady state energy production (likely not for several decades), since it took 300 megajoules of electricity from the grid to power the relatively inefficient lasers’ delivery of 2.05 MJ to the target — but a promising demonstration. Read about it in the NYT here.
