Why is fusion always “30 years away?”

1.61K 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?

I say “I can build you a car in a year for $10,000”. You give me $10/month. A year later you come back and I say “I can build you a car in a year for $10,000”.

Why is the car always a year away?
