If we have to go nuclear, we need to accelerate development and deployment of nuclear FUSION.
Fusion has been just 20 years from reality for the last 50 years......
When I was in grad school in the mid-70’s, my advisor, whose PhD thesis was the 2nd most widely cited paper at the time on one aspect of fusion (tokamak) reactor design, said that we needed 20-20 vision to see an operating tokamak. By that, he meant it would be 2020 before it would happen.
While I don’t follow developments in fusion research particularly closely, I don’t think that we are any closer today toward solving some of the fundamental issues than we were 35 or more years ago. The technical issues are formidable.
