you make good points,
But to be realist, the hard-skeptics can be good observer when it serves their cause, and absolutely blind when it oppose their cause.
The problem is that on many points they propose absurdities, and in the mass of crappy conspiracy theory, they have few good points.
Most of them are dead clock which are right twice a day.
Other points is that if they raised possible problems, they also did not have strong evidence, just suspicions. The problem is that they would suspect their mother to be their father if it could support their beliefs.
That demo was a demo, a pony show, this mean proving nothing, not even failure.
There was good remarks, from people who probably had data from Luca Gamberale (like Cimpy), but it was hard to check, by design.
Since the beginning it was clearly not a third party test.
As I said multiple time, we could not condemn them, but sure we needed more data, on the water flow, on the quantity of water used to cool the steam. I computed that few liter per minute was required to condensate all the steam claimed, and Mats said he visually estimated it was much less... but there was so many variable, like condensing in copper tube, in the sewer... Impossible to have a definitive opinion, and given the past bias of skeptics I could not trust their claims about whether something is possible or not.
There was doubt on the HV supply, but again not enough data since only apparent current was measured. In the report Luca confirm the electric measurement were good however. The skeptics were wrong that time, like on most of their claims.
After few month of no answers to Luca, things get scary. When Symeon left the company, when Luca closed DE, it get very scary, but until recently we could not do more than suspect or fear. That time like many I have great doubt but no evidence.
When Luca Gamberale published that it was badly done, we had, at last, data. The fact that Defkalion answered nothing since 9 month clearly shows they cannot face the facts and it gives strong reason to trust that very expensive report that costed 1million to DE.
The most annoying evidence was the Nelson report, that was not definitive. The real error was to consider it as an evidence of a moderate COP>3, while the author confirmed it was preliminary, and nothing was done after.
I don't know if Nelson was fooled like they tried with Luca, and in the report you find reason to hope he avoid to be tricked the same way, but no certainty... and nothing exclude others tricks.
What Luca denounce is enough to abandon all trust in that test.
There was also many warning from various actors, like Jed or Stremmenos, but in that domain it is always hard to separate passion, commercial interest, manipulations, nationalism, gut feeling, experience, and good intuition. Moreover if you look at Rossi's story, or Wright brothers story, there are many catastrophes and stupid mistakes that could be badly interpreted.
Just read the paper of Pomp&Ericsson, and you will see that most of the critics are pathetic, hiding or missing the few good points, like DC offset, in a web of conspiracy theory. Re-read the article against Andrea Rossi, and compare to recent knowledge and data... It is not lies, it is disinformations, biased presentation of many real facts and some inventions.
I disagree mainly about skeptics, as they are of so much bias and irrationality that they are more an obstacle than an help to debunking. They push careful observers to be radical, emotional, to behave like attorneys and not like judge, as they behave like a desperate death-row attorney.
Find something that, before Luca's report, they said on Defkalion, that was not already said on Rossi. They are constant output function.
Once we have honest critics that admit facts, and raise concerns with moderation, admitting they are not sure, it would be easier to separate the sure good from the possibly bad. That is what we are missing the most, moderate critics, moderate supporters...
This is a reason to hear the opinion of Jed Rothwell who expressed various skepticism but not absolute certainty, and avoided usual fallacies.
I admit I screw up badly, trusting DGT without any serious contacts with them, despite few alarms,despite no delivery, despite many stupid announces, at the same time being very skeptic against Andrea Rossi whom I treated quite unfairly.
If some remind, I consider about industrial LENR actors that there are only 3 interesting evidence :
- Levi's report, the best one, which beside DC offset question is solid. (unless Rossi is stupid like DGT, injecting DC that one of the physicist can measure with a 5$ voltmeter is not credible). I hope next one will be rock solid.
- Tanzella's (of SRI) paper presented at ICCF17 showing COP of 2 for Brillouin WET reactor. Not really 3rd party, as SRI and Brillouin work together, but quire credible given SRI is not a scam artist.
- The Nelson "preliminary" report showing a COP of 3 for Hyperion... This report is confirmed but not definitive, not detailed, not very independent, and now I consider it as possible pony-show. To be removed from the list.
Beside that you have numerous scientific articles, which let no doubt about the reality of the phenomenon with PdD, but little hope of short-term application. this is a separate question.
