We’ve been working on fusion in one form or another for nearly 100 years. We’re still nowhere near turning it into a useable energy source. I don’t really care if research continues or not, I’m sure the research can be useful in other areas but fusion is not going to save us.
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.
It’s not though, not withstanding stars. We’ve managed 17 minutes so far. We’re so far away from turning this into a useable power source that it’s absurd.
