They had to ask him for context as to why the car was towed in. The steering wheel had literally fallen off.

Besides being cool, and being another step forward, what is the scientific significance of net positive energy in fusion experiments?

What I mean to say, is generating 2.04 much easier than generating 2.06? Is there some barrier that makes crossing that net barrier so difficult?

In my mind, I am comparing this to a perpetual motion machine. The big barrier there of course are the laws of thermodynamics. The difference between 99% and 100% efficiency is huge because that would mean a fundamental law of the universe is not actually true.

Net positive energy on the other hand seems more arbitrary and perhaps more of an engineering achievement than a scientific achievement since the implications relate more to scale. I know nothing about fusion so am seeking to learn.

(Not to downplay anything, I am just wondering about the scientific implications)

To be fair most gold and precious gems are pretty old.
