It’s shocking how few people understand nuclear energy doesn’t have to have radiative waste and it doesn’t require mythical physics. It’s called aneutronic fusion and it’s accepted conventional theory. We just have to actually fund the research and we could have plenty of cheap and clean fusion energy using hydrogen boron fuel.

We also have nuclear battery technology that is getting impressive and it’s feasible we could find solutions that are eventually cost competitive using relatively safe materials.

Also, current compact fission reactors designs are projected to go on the market by 2026. They have a ceramic coated fuel source to make it more safe and this likely will eventually become cost competitive with natural gas for certain industrial markets.

I’m glad your also open to cold fusion. The DOE is funding $10M in this research is it’s a long shot but deserves more attention.
