With a couple of years of development effort we could build a medium sized nuclear reactor that would be extremely save, extremely fuel, cheap fuel (essentially free), extremely reliable and it would solve availability issues.

You can literally mass produce the reactor and send it to standardized facilities all over the place, on or of the grid.

This would not even be very costly, a robust reactor development program to start with and some commercialization of the tech and regulatory change to allow it. No Manhatten projected needed.

I think doing what you suggest and replacing all coal and natural gas plants with reliable energy is pretty insane in comparison. Not to mention that that is only the easy part of the problem. I don't know a reliable way to solve the availability issue. The only close to viable approach is Musk-Style mass production of batteries. Even that is only viable if we continue to make leap and bounds improvements to batteries.

This is about solving the energy needs of 10 Billion people in this century. A Manhattan style mass production of solar cells and wind turbines will not get it done.

Thorium has the highest energy density and its practically unlimited, both in the ground and we already mine it. It simply is not that hart do build a modular reactor that can be mass produced. We know it works, and we know that it solved all the problem we have, including availability, pollution and global warming.
