Regarding the Google Hangout platform, it's not necessary to have a mic or camera online, and both can be disabled easily. The important point is that there is a text chat facility that we use exclusively for these events. You enable the text sidebar by clicking on an icon at the top left of the screen. The icon is hidden until you mouse over it, and I apologize for not mentioning that earlier. A transcript of the text chat will be included in the archive if and when available.

Unfortunately the Google Hangout video stream apparently isn't being logged. That could be useful as a reference before the actual raw data gets released. I often used previously recorded MFMP tests on Youtube for this purpose.

EDIT for chat logs, I think it would be better to provide just a summary with key points and links.

How much below 1 bar? It sounds like there was a breach.

@Majorana: if you're referring to the total amount of hydrogen in the cell regardless of pressure, you're correct: there's a very little amount of it in Holmlid's experiments. Since everybody keeps referring to the LENR-active element as "fuel", I thought you were writing about Holmlid's iron oxide catalyst.

As for Rossi, of course we cannot know for sure whether he actually used pure H or also mixed in some D with it, perhaps using LiAlD4 as a hydrogen source. The Lugano report did state this however:

Quote

[...] It is plausible that the fuel is mixed with the standard Lithium Aluminum Hydride, LiAlH4 . Further evidence of that is obtained from the ICP-AES analysis which shows that the mass ratio between Li and Al is compatible with a LiAlH4 molecule. This compound can be used to produce free hydrogen by heating. We remark in particular that hydrogen but no deuterium was seen by SIMS. The other methods are insensitive to both hydrogen and deuterium.

The general assumption is that in LENR experiments successfully working with protium, deuterium could bring out gamma radiation and possibly even neutrons. That's what Celani and others are reporting though, it's never been really confirmed. I often advocated for trying that out.

EDIT in answer to your edit:

If we assume that 1. Rossi can be taken serious at all and 2. Rydberg formation is the real mechanism behind all LENR as Holmlid claims, then obviously Rydberg H is also formed under high pressures and under a considerable O2 atmosphere. Question is why. Maybe here the additional Lithium could play a role. Rossi has never evacuated his alumina tubes to pressures Holmlid is talking about before running the reactor.

A possible hypothesis I came up with recently is that lithium could be merely acting as a hydrogen getter, and that the inner ceramic tube (was it actually alumina like the outer cement? Nobody investigated...) could have been treated for being both unreactive to lithium and porous to hydrogen. Appropriate temperature/power control would then allow to release gases from it in desired amounts.

This hypothesis implies that the reaction environment isn't within the inner cavity, but could instead be on the heating wire (perhaps its oxide layers) or at the interface between the heating wire and the ceramic tube permeable to hydrogen. It's a wild hypothesis which nobody can confirm right now. It would also make finding an explanation for the isotopic changes reported difficult.

Holmlids experiment can't easily be compared.

You're right, but if Rydberg Matter is behind LENR, using a relatively low pressure and applying a good initial vacuum could be important. This is not unlike what Piantelli also does.

Quote

He is using a vanishingly small amount of fuel and his experiment was designed to be a proof of principle.

In his experiments he uses cylindrical iron-oxide catalyst pellets of roughly 1 cm in length and a bit less than 0.5 cm in diameter. They are small, but not orders of magnitude smaller than the supposedly active core in Parkhomov replications.

Assuming that Holmlids hypothesis is right and all LENR phenomena are Rydberg matter reactions, one interesting question is however: Do we maybe need LiAlH4 with Deuterium as bonded Hydrogen instead of Protium?

Holmlid and others also detected ultra-dense protium, so it might not be necessary.
However, some LENR researchers reported observing ionizing radiations when using deuterium instead of hydrogen (protium) - so it could be a better choice if one wants to simply demonstrate that LENR are an existing phenomena.

Quote

And could a lower pressure facilitate the formation of Rydberg deuterium on the Nickel surface?

According to Svein Ólafsson on LENR-Forum:

Quote

Bad vacuum H2O, O2 and ions are disturbing the Rydberg matter and therefore eventually also the ultra dense form but once formed it can survive better

Not Rydberg Matter (perhaps - but what if he is actually observing the very same phenomenon?), but according to Piantelli in his patent:

Quote

Advantageously, during said step of bringing hydrogen into contact with said clusters, said hydrogen has a partial pressure set between 0,001 millibar and 10 bar, in particular set between 1 millibar and 2 bar, in order to ensure an optimal number of hits between the surface of said clusters and the hydrogen molecules: in fact, an excessive pressure increases the frequency of the hits, such that it can cause surface desorption, as well as other parasitic phenomena.

@LENR Calender: the chart tells how much of the lithium available forms LiH in a constant hydrogen atmosphere at various pressures and temperatures. At a LiH mole fraction of 1 it's 100% LiH; in other words all the lithium is LiH. For all intents and purposes it's the same as H/Li atomic ratio.

At 903°C and about 26^2 torr (901 mbar) the LiH fraction in Li can range between 0.46 and 0.86: LiH formation is unstable
At the same temperature and 20^2 torr (533 mbar) the LiH fraction will be about 0.26
