Is there evidence for LENR power generation of 100W for days without input power?

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.

(sorry if typos, it's late and I am using a small tablet)

This is not going to be a thread where someone waves their hands wildly and presents papers that don't show what Jed says are simple and absolute facts. At least I for one won't respond to miscellaneous crap. There is nothing vague or conditional about 100W, no power in, and days of running. I looked at what Zeus provided and none of it is 100W, no power in and days.

For example Cravens spheres generated more than 100 watts on their own.

No. I think even Dennis only claimed 4W for his infamous balls. That sort of glib misrepresentation is another reason LENR enthusiasts get little respect from the scientific community. I think Shanahan had an explanation. I don't recall it offhand. Maybe he can point to where it was-- not write it again, just point to it. Thanks. I can also do without the "skeptopath" bullshit.

BTW, the Chinese review paper begins with a credulous take on Rossi and the second item is MFPM's high temperature Ni-H test so I see no need to go further. Anyone who attends uncritically to those doesn't interest me in the least.

So you spent five years searching for your holy grail... found it... lost it, and now can't remember anything about it? Disingenuous, toi?

Another inane mischaracterization. I found a possibly interesting article but misplaced the link. Jed has it. Maybe he can produce it again from my description so we discuss it. Your attitude is typical and is a reason most scientists don't deal with LENR enthusiast believers at all.

Don't ask for mysterious papers without a name, then whine about people sending you papers. Who knows what you thought you read?

I described it as clearly as I could. Who knows? Obviously you don't.

Anyway, all this talk of 'no-input for days' smacks of being one big goalpost-shifting exercise, as uncannily predicted by Rothwell here:

So now, asking somewhat to produce what they claim is goal shifting? And you wonder why people won't even engage with you any more? Rothwell said 100W, no input, days. That's all I ask that he produce. Not the slightest shifting whatever. I asked him if he really said it and he admitted that he did. The ten days was just an arbitrary number used to show that even at that duration, some conventional energy sources of feasible size and weight could conceivably account for the heat production. That simply points out the need for caution and careful inspection of the device. That's all. But all such conjecture is premature and silly, isn't it? Because I am pretty sure Jed was just blowing smoke anyway.

Well, Zeusie, if it starts with a noncritical discussion of two obvious scams (Rossi and Parkie) and one experiment which failed (MFPM), perhaps one can see why I am not especially interested in reading further. Anyway the paper you furnished seems to be a review. The one I misplaced described the author's own experiment and was not a review.

Hey Mary, you utter pillock, on the one hand, you ask for papers that:

Wow. I had to look up "pillock" -- seems to be a British colloquialism. Charming. Is it open season on insults now? Because if the admins have rescinded their discouragement of insults, I can happily teach you some new words you richly deserve but which I withheld out of consideration for our hosts.

I'm done engaging with you because you obviously know little or nothing about LENR research. Rothwell probably ignores me because he spoke out of his posterior and the study he claimed doesn't exist. That, I suspect, explains the dearth of helpful responses. Here and in corresponding other threads. There probably is no credible work showing LENR providing 100W, Days and no power in.

It is not open season on insults. I just don't have the energy to deal with this stuff right now.

That's OK. Insults from Zeus are meaningless anyway. Insults only matter if they originate with someone you respect.

Quote

They showed an example that ran for 3 hours in the paper I pointed you to, and other papers show a day or two.

Could you please provide a link to those other papers for the devices that ran unpowered for a day or two? Also one of the papers (hopefully the best one) showing excess heat of >100W sustained for 3 months with input power? Thanks.

Good point. Coming up with 100 Watts is a bit capricious just on the face of it. For instance, when Hagelstein demonstrated his NANOR for several MONTHS, it was never more than what, 50 mW or so? But the output was several dB above input power, which would be the true threshold.

It is a mystery to me why such insulting comments are not immediately shunted off to the garbage thread, Clearance Items. Something about some animals admittedly being more equal than others.
