> why not fusion powered ships/trains/airplanes[?]

What could possibly go wrong?




Afaik what makes fusion hard is maintaining the conditions that allow fusion to occur. Because of this, it’s quite safe - if anything goes wrong, it’ll just stop working.


Safe? Really?

I expect that the containment vessels will get very radioactive.

But all a bit hypothetical, since none exist


Yes they do exist, link elsewhere in this thread, Helion have a 7th generation nuclear fusion reactor fusing once every ten seconds or so. https://www.youtube.com/watch?v=_bDXXWQxK38

(It's not surplus of power, but it is repeatable fusion actually happening).


That is not a fusion reactor


We already have fission powered ships and submarines.



Sense prevailed, and we do not have civilian mobile nuclear reactors.

The military are mad. Mad and bad. It is in the job description.

We would all be better off if none of them (the military) existed
