It’s being worked on. Repetitive shots aren’t as ideal or obvious as a quasi-stable reactor, but a pulsed system will still have its output effectively smoothed in process of heating a thermal jacket or liquid first wall.

Statistics, high speed computing which I’ve assisted with previously, and other techniques are likely to get the rep rate to at least 1hz with the occasional miss.

Certainly ironic that we’re making what feels like a nuclear combustion engine. Old tech, same as the new tech…

There are also a lot of manufacturing difficulties with tokamaks. The magnetic flux density is much stronger at the inside of the torrid vs outside, since all the torroidal coils must meet near the middle. So there’s an issue of “barely enough magnetic force” at the outside, “too much” force on the inside, which adjusting for or adding compensation for potentially further decreases system efficiency. And that’s the goal, getting to thermal breakeven.

What would you suggest?

Luxottica. I’ve visited their HQ in soCal, people aren’t having fun and coming up with wacky designs anymore.

Mmm… I wouldn’t say that it’s difficult to scale. Getting fusion to happen is hard, but repeatedly is simply an engineering problem (still hard, but less so).

Cool, but how about some examples, pictures, ideas? I agree with the article otherwise.
