Cold fusion is a pipe dream. Deuterium-tritium fusion is on the way and will be putting elecric power into the grid by 2050. In Europe of course. The USA is not interested in doing such things domestically. This fusion is not the final answer since lithium reserves would be gone in 1000 years. Peak Lithium is still a ways off. Peak Uranium would be here this century and probably sooner rather than later but that is the old fission type nuke.
Well, we could postpone that if we would get sane and use breeder reactors like France does.
Thanks, Jimmah.
