Do you have a basic understanding of the challenges of getting electricity from a fusion reaction vs the challenges of manufacturing PV panels?
Seeing as you deliberately seem to be missing the point in order to try and feel smarter I’m going to leave you to it. Have a good one.
I asked a question, a relevant one. Your reaction to that question is your problem.
So we should just give up? No.
We can carry on throwing money at it, I'm fine with that. Thinking that fusion is going to save us is dangerous though. We need to be taking action now to get us off fossil fuels and the most cost-effective way to do that is renewables + storage.
The first challenge is that nobody knows how to sustain it and have been researching it for 80 years. That's a pretty big one...
i think a central barrier at the moment is fusion doesn't readily start a chain reaction like fission can. scientists are likely exploring the use of the yield of the fusion reaction to reload the reactor (kind of like an automatic firearm) and these techniques are far from mature in this setting.
PV is a simpler mechanism in every way and we've been studying it for more than 100 years. They're very different both technologically and maturity-wise
The sun is a fusion reactor which is sustaining a reaction for millions of years already. Iter is a concept which tries to emulate this
