Why is fusion always “30 years away?”

1.35K viewsOtherPhysics

It seems that for the last couple decades fusion is always 30 years away and by this point we’ve well passed the initial 30 and seemingly little progress has been made.

Is it just that it’s so difficult to make efficient?

Has the technology improved substantially and we just don’t hear about it often?

the version of the joke I’d heard from people involved was that it always has and will always be 10 years away. granted what NIF did was a breakthrough. So maybe it always will be 5 years away now
