Could someone enlighten me how laser fusion of prefabricated pellets (at least that's how I understand the idea in the article) can generate electricity? In a Tokamak or Stellarator, we collect heat on the outside, AFAIK and generate electricity in the good, old, "make something spin quickly" manner. But in a laser-ignition device, we need to shoot a pellet into some kind of chamber, so that chamber better be relatively cool or our pellet melts or deforms before it can be hit by the lasers, right? So how does one tackle that problem?
