The US Navy is now the assignee for a LENR ("Cold Fusion") patent. A patent does not prove a new technology is real - by itself - but the surrounding details strongly suggest to me that the US Navy is serious about this matter and may be looking for a new powerplant technology.
The scientists involved in the patent development are well experienced and deeply knowledgeable in their fields (such as Pamela Boss). Some have suggested that experts in electrochemistry may be more favorably inclined towards "Cold Fusion" than mainstream physicists. There is also serious criticism that the term "Cold Fusion" should be abandoned in favor of some other term.
In any case, if the technology is real and can be made practical - everything changes.....
