    The only one I heard news about breaking even was that thing that shot a lot of lasers to a pellet. For a fraction of a second It broke even or produced slightly more than they poured in, but it was much less of what they spent.

    There’s been something else new?

      I saw a talk on the subject about a year back. It was discussing tokamak reactors, from an engineer working on them. The small ones can’t sustain a break even state, but they are affected by the inverse square law to a larger degree. I believe China is about to start/has started construction on a power station sized test reactor.

      The pellet sort are a different type. They have different pros and cons.
