Sure, just insure your advanced fission reactors against desaster with a prudent insurer instead of relying on the government to bail you out in case anything happens. Proving something with long-tail risk is secure takes ages.

There are just too many ways to store energy to go through them here, and it doesn't make sense to take any single one and claim it cannot scale to the problem at hand.

I guess we'll just have to agree to disagree on the difficulty of storing energy vs. getting nuclear fusion working.

I think fusion would be great to have and research is important, but i'm also glad that we don't need to get it working real soon now.
