Guess what's still plugging along?
Cold fusion!
Haven't checked this out in years. The "transmutation" bit is new.
This has always been an odd field in my view. One would think that they would have cracked it by now if there was anything to it. A large part of my mind places this in the same category as many paranormal studies: generating vast amounts of detailed and fascinating research, but not actually ARRIVING anywhere.
Come to think of it, most hot fusion programs fall into that category too.
