Fusion has been 25 years away for all of my life.



Fusion is net positive energy now; that happened in 2022 (+54%).

In 2025 they got a 313% gain (4.13 output factor).

Fusion is actually here and working. It’s not cost effective yet but to pretend there has been no progress or achievements is fundamentally false.


Negative Negs spit out low effort snark, they said the same thing about solar, electric cars, even multicore, jit, open source. Thanks for refuting them, the forum software itself should either quarantine the response or auto respond before the comment is submitted. These people don't build the future.

Yes it’s a net positive if you ignore the 100x extra power it took to actually run the reactor, so actually no it’s not net energy positive. Not even close.

Nothing to do with cost, we can not build a fusion reactor in 2025 with any amount of money that will produce more energy and goes into it.


It isnt when you look at Q total. Total energy input for all needed support systems versus energy produced. See https://en.wikipedia.org/wiki/Fusion_energy_gain_factor for more details


It will be cost effective in just 25 years.
