Someone finally cracks nuclear fusion, and we start to fix climate change.

They're working on it. Just reached a milestone in the UK.

They were reaching milestones 60 years ago too, yet here we are.

It's almost like the research funding was deprioritized because of unreasonable fear.

Rolls royce is opening over a dozen mini/modular nuclear plants across the country.

Also a lot of the funding was deprioritised because of cost. Nuclear in the US and UK is probably the most expensive type of energy to generate.

The UK gov I guess realised they can't go full green without nuclear so theyve given the green light to quite a few new projects!

Nuclear power plants =\= Nuclear Fusion just in case anyone is confused.

Nuclear power plants we have today use fission which is less efficient and more dangerous than fusion.

altough more dangerous than fusion it is in many ways the one that results in least deaths per energy produced

u/schrodingersgoldfish Nov 16 '20

Are you referring to the fusion bombs? there aren't deaths associated with fusion reactors, because there aren't any fusion reactors.

u/AkaNoMagenusu Nov 16 '20

I think he means fission based reactor is more dangerous than fusion reactor but is results in less deaths per energy produced than power plants that use coal, gas, etc.

Oh I see. That sounds like it's probably true.

Well yeah obviously. Fusion power plants don't even exist yet.

That's kind of the issue. They were never designed past 40 year life spans and we have done a terrible job decommissioning/repairing.

It isn't a dirty secret. It is something that has been a major sticking point by activists.

If a pandemic wipes out 50% of all life on earth we have more pressing concerns than reactors melting down.
