Suspect it will still be a long road towards running production.
the technology is a lot harder to scale up then say a nuclear fission reaction

That's easy in comparison, hell it's just a question of getting teh materials in place with a moderator.. and then getting the heat to a turbine
the main issue there is doing it safely and the waste products, but the reaction itself is easy to achieve.

Fusion, containment of the fusion is incredibly complicated , the bit that makes the power won't run on it's own and it requires very complicated containment to even work.
They too 40 years to just get 5 secs worth of power (it's not even usable power at this point) equivalent of 60 kettles of tea
Scaling that up?
actually getting the power converted to electricity?

I'll be a lot greyer then just my sideburns before it delivers current to my house
