Low Energy Nuclear Reactions, Part 4: Revival, Theory, and the Road Ahead
23:04
Part 4 of 4, the finale. Cold fusion never quite died — and lately it has been revived by unlikely backers. We trace Google's multi-year, multi-lab investigation and NASA's lattice-confinement work, the newer research programs now funding the field, the stubborn theory gap (there is still no accepted mechanism), and where the most credible next breakthroughs might come from. We close by weighing…
