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.

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.
