Nuclear fusion, explained for beginners

I would also like to see more development in non uranium based fission reactors.  The only reason that we have uranium fission reactors is because weapons grade material can be extracted from them. That is also what makes them dangerous.   There are other fission reactor designs that can’t melt down and don’t make any weaponized byproducts.   They just haven’t have had the R&D to make commercially viable reactors yet.   The nuclear panic is still very prominent in the world.
