Jed Rothwell has repeatedly asserted that there is significant and credible evidence for an LENR device which sustains a 100W output for days without any input power. If the device runs at 100W for 10 days (240 hours), the energy it would output would be 86.4 Mega Joules or 8.64 * 107J. Although this sort of output can (just barely) be spoofed by chemical or electrical sources, the simplest inspection and weighing of the device could rule it out (see note below). One or a few credible examples of experiments involving a device with the above performance would go a long ways to proving that the device was generating anomalous heat. I think finding this device if it exists is worth a discussion string of its own.
I've been looking for good evidence for the existence of this sort of performance for five years. Jed has suggested a number of papers. I always at least browse his suggestions and I've read quite a few and even understood some, LOL. Most were very forgettable for me but one was not. I managed to misplace it but I remember power output was high (>100W) for a long period with low power in (it wasn't zero). I don't recall the author (maybe Japanese?) or the technology so that is not very helpful. I do remember that the paper seemed incomplete as to materials and methods. If someone can help me find that again, I'd appreciate it. I never saw any paper jed suggested which described a device making 100W out for days with no power input.
I would appreciate it if anyone can help me find either the paper I misplaced or a paper or report which describes a device that purports to do what Jed claims. For some inexplicable reason, Jed so far hasn't been willing or able to provide a simple link or even an old fashioned reference to a paper journal. If he can't, maybe he can explain why not.
Jed mentioned that we didn't reject Dolly the Sheep, transistors or other low yield technologies. But a single sheep can be examined and studied, a single transistor that works can be tested for its properties and demonstrated in amplifiers and oscillators, and so on. Similarly, a single LENR or cold fusion reactor which made 100W for days without any input power would go a long way towards convincing investors and even many if not most main line scientists that there was something there that badly needed exploration.
Note: 8.64 * 107J seems like a lot but by comparison, a gallon of gasoline contains a bit over 108J. The best battery has an energy density of about 500 Watt-hr per kg or about 1.8 * 107J for 10 kg of very good batteries. I only mention it to point out that it is still necessary to be sure the information comes from honest people because it is somewhat feasible to spoof that level of power generation with chemical or electrical means. It isn't easy or likely but it is remotely possible. If someone can come up with evidence for the claim, we can discuss whether it was made by real scientists in real labs or came from scammers. I will go on record to say that those I have called derisively the "usual suspects" (McKubre, Hagelstein, Swartz, anad Storms for example) seem to be very honest in my estimation. I would be more skeptical of some Russian and Indian research but again, we can sort all that out if someone comes up with the evidence and data.
Finally, it does strike me as strange that Jed, for whose good intentions and work ethic I have considerable respect, makes this claim and won't tell us where it came from.
