This thing is being hyped beyond reason. They haven't even figured out how to extract energy out of this process. In order to have a functional power plant they'll have to zap these exquisitely machined cages with pellets of fuel at a rate of maybe 10 or more a second. Because the cage is made of gold, they also have to figure out a way not to have that vaporized gold coat the chamber. The lasers that fire at the pellet now take hours to charge up for a single shot, but remember they have to fire at a rate of 10 shots per second. They've advanced the research a little bit, but they're still very far from having a practical energy source.
