I have this same issue with fusion. Who cares if the fuel is practically free, when building and operating the plant is extremely expensive and prone to failures due to the sheer complexity.

Of course the tech and science is cool, possibly useful in space or other niche environments, but whenever I see fusion proposed as some general energy solution, I just roll my eyes and move on.

People really love scifi on hn, and that's fine ... but the investment capital has spoken and renewables are being funded 30x nuclear. Not 30% more, 3,000% more. It's even 2x over ogc infra (oil, gas, coal)

It's a 12-1 over OGC in what the IEA labels "advanced economies" https://www.iea.org/reports/world-energy-investment-2025

We'll have direct antimatter annihilation at scale before we have fusion. It's basically a physics research project, with zero potential for commercial use.

There's already a convenient fusion reactor fairly close by, and it's unlikely to stop operating any time soon.
