Why is fusion always “30 years away?”

1.36K 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 truth is that we don’t know if energy generation with fusion is even possible, other than with gravity holding things for free like in stars. We are very very far from demonstrating any kind of net energy generation once the whole system is considered.

Even if it’s possible, it’s far from certain if that would make any economic sense at all.

But they don’t want to tell you that, so they make up stories about fusion being 30 years away.
