I'd love to learn more about the actual methods they're pursuing. One I like and related to cold fusion is muon-catalyzed fusion. Theoretically, it should be possible and dramatically lower the temperatures required for fusion. Muons are like electrons but much heavier and less stable. When a muon replaces an electron, it allows nuclei to get much closer together, lowering the energy requirement for fusion. The practical challenge is creating muons with less energy than you get from fusion. https://en.wikipedia.org/wiki/Muon-catalyzed_fusion https://en.wikipedia.org/wiki/Muon-catalyzed_fusion
