Because they disapprove of cars and of energy production.
No they don't, they disapprove of fossil fuels and stuff that creates carbon dioxide. I don't think anyone would have an issue with cars if they were cleanMicro rubber particulates off the tyres.
Killing bugs as you drive through the air.
Noise!
Screen-wash water pollution.
It’s a never ending battle against complainer personality types.
I'm sure there's plenty of threads on Nimbyism, Eco-terrorist conspiracy, UFO, mind control and alike, fill your boots and leave the interesting science alone.

Mods need to do a thorough cleanup of this thread. Conspiracy nutbags have plenty of space to dribble in NP&E.

Well I've been enjoying reading this thread and watching the ITER stuff on YouTube. Some insane engineering going on there. Will be exciting to see where it goes.
Hopefully this thread can avoid being derailed by the strawman types.
ITER sounds like an absolute monster. Hopefully this thread can avoid being derailed by the strawman types.

Watching this interesting piece though there's some promising developments in far smaller (and hopefully quicker to construct) models.

This would result in a Q-power of about 1.2.
They would then need to build an even bigger reactor, with steam generation, you need a Q-power of about 50 to make a commercial fusion power plant financially viable, you're looking at ~30yrs min before anything remotely practical as a power plant.
If this was a private project, the investment would have been put into alternative solutions.
I remember JET was well established and reading about the initial planning for ITER when I was at school. I'm closing in on retirement.
I don't know if it's the usual issues with an international project (20 ish years for the ISS to get going) or going slowly at the rate the funding comes through (like all the paper rockets that NASA designed in the 90s and 00s).
But it certainly doesn't strike me as likely to deliver much - perhaps it is just a problem that is too hard for humans to solve.

It is all gradual steps to solve specific issues-

"Major breakthrough on nuclear fusion energy"
The experiments produced 59 megajoules of energy over five seconds (11 megawatts of power).
"The JET experiments put us a step closer to fusion power," said Dr Joe Milnes, the head of operations at the reactor lab. "We've demonstrated that we can create a mini star inside of our machine and hold it there for five seconds and get high performance, which really takes us into a new realm."

Until they hit unity or net gain, it's all for naught.
Large reactors using magnetic confinement are on a road to nowhere.
Inverse Square Law
For commercial use, unity isn't even the target. For something that outputs power like a commercial powerplant, the actual goal is somewhere north of 30:1.Large reactors using magnetic confinement are on a road to nowhere.

Why not throw eleventy billion trillion at the problem?
Feel free, but you'll get less than 1% back. CraigyMc said:

Because they would be massive and hugely expensive.
They still have the nuclear waste mess to deal with at the end as most of the system will have been bathed in neutrons for it's operating life. Obviously not as bad as fission, but still significant.
