Besides being well-written and documented, it seems to describe the holy grail - repeatable fully characterized room temperature superconductivity.
To be exact: They write "the signs of room temperature super conductivity". See their conclusion given next line:
"In conclusion, we describe observations that strongly suggest the emergence of superconductivity in an Au-Ag based material at ambient temperature and pressure conditions."
What we know its that the energy transport mechanism in the SC build up phase can also be use to ignite LENR. In the SC build up phase a spin currents may synchronize more than 10e12 electrons, what even at energy levels of 10e-7 Volts/electron can result in a strong (total) stimulation.
Interesting paper reflecting difficult scientific work. While it might lead to netter understanding of superconductivity, what they are doing would be far too expensive to extend the use of SC much.
What is electricity?
One definition would be the motion of charged particles such as electrons.
However, I don't think we will truly understand superconductivity until we realize that electron current is only a byproduct of electricity and not electricity itself. There is a force pushing the electrons from one end of a conductor to another and there is a carrier of this force. Once we gain an understanding of the structure and dynamics of the aether, we will be able to design all sorts of "super conducting" materials -- if we have not already with what has been described by some as "cold electricity."

If a superconductor has zero resistance, can it be infinitesimally thin, and still transmit a useful amount of power?

Sorry, no. Superconductors have a limiting magnetic field that limits how high you can make the current density. Current carrying capacity increases as you chill the material below its nominal superconducting temperature. There are superconductors that work at LN2 temperature (77K) but do not have useful current carrying capacity at that temperature. This is why MRI machines still use expensive LHe.
My surmise: a single (i.e. one shot) very brief, super-critical discharge, that is, far above the critical current density for sustained superconductivity, might "sneak through" via some mechanism. Perhaps transient transmission of the excess "supercritical" current pulse via surface "image" positive charges traveling via relatively immobile positive ion to ion "hand offs", which might remain at least charge balanced by above -surface mobile electron flights. That is likely to be expected, and likely seen many times.
More difficult and more interesting, and showing only when the superconductive critical current density is exceeded, but before thermal destruction of the SC state, and at very high transient field gradients, one might observe near condensed surface the equivalent of "vacuum" or diffuse plasma pair (e+ and e-) production. Perhaps further enhanced by surface oscillating square waves (many examples in LENR, including the Lipinski patent). Hypothetically, at least a relatively easy positron and/or electron escape in the context of such surface condensed lepton / ion charge mobilities.
As many here know, that is not really relevant for sustained power use or production. On the other hand, it could easily provide useful information on materials and processes for further R&D. An "interface" or surface-associated field gradient of great intensity, yes. The possibility of released leptonic charges, yes. Over-unity spikes, sure, from several sources including store / release, measure errors in charge-noisy, EMF-noisy environments.
But net, overall, energy gain? Perhaps not as easily, if at all. But still it is here that the information and "theorizing" provided by "Eros" is worthy of some attention and perhaps further, and a bit less "hopeful" empirical effort.

There is a lot of literature about SC in arXiv especially written by Hirsch.
As a starter: arXiv:1201.0139v1
For people interested in the phenomena I recommend that they first read through it (and the other arXiv SC papers by Hirsch). Hirsch, in an other paper, also makes speculations about e+-e- pair production in a strong SC field. But he mixed up some formulas... Nevertheless, in the limit SC and LENR are very similar as both are spin effects.
It looks like there is some controversy about the paper on room temperature superconductors. See:
https://arxiv.org/pdf/1808.02929.pdf
It seems that two of the graphs, with data taken at different times, have identical noise patterns. He stops short of calling it fraud, but there is a big twitter conversation about it.
Hi Robert. I don't do Twittering, so can only read the paper you link. Surely it is not unusual for the s/n ratio to decrease as the signal increases in strength? It can be a function of equipment quality and method, I am well aware that the superconductivity field is as full of backbiting and competition for resources as the LENR field, having had extensive email dialogues with several key players, so wary of any criticism coming from someone claiming to post it a critique 'at the urging of a colleague'. And MIT are no angels I'm afraid.
Hmmm.... Shifted the green dots down...
The unusual part is not the s/n ratio change. It is that the green and blue dots, from two different independent experiments show exactly the same random noise, but with an offset. If you think of the up/down variation from sample to sample as determined by flipping a coin, for the flat part of the curve they flipped it about a hundred times for the green experiment, and when they did the blue experiment they got exactly the same sequence. The twitter feed shows a zoomed in version where you can see that more clearly.

Bose Einstein condensates are superconducting. BECs that are not dependent on temperature for their formation can be superconducting at any temperature.

This is nonsense, if you don't give the full build out formula, that contains pressure/density & geometry!

Polariton condensates at room temperature
Abstract
We review the recent developments of the polariton physics in microcavities featuring the exciton-photon strong coupling at room-temperature, and leading to the achievement of room-temperature polariton condensates. Such cavities embed active layers with robust excitons that present a large binding energy and a large oscillator strength, i.e. wide bandgap inorganic or organic semiconductors, or organic molecules. These various systems are compared, in terms of figures of merit and of common features related to their strong oscillator strength. The various demonstrations of polariton laser are compared, as well as their condensation phase diagrams. The room-temperature operation indeed allows a detailed investigation of the thermodynamic and out-of-equilibrium regimes of the condensation process. The crucial role of the spatial dynamics of the condensate formation is discussed, as well as the debated issue of the mechanism of stimulated relaxation from the reservoir to the condensate under non-resonant excitation. Finally the prospects of polariton devices are presented.
Polariton condensates at room temperature
Yes: As we know since LENR. It works in cavities, because they have the same effect as a huge reduction in pressure. But it is not classic BEC! It's based on quasi-particle resonances.
But to write they are not dependent on temperature is not correct: Correct: They can occur at moderately "high" temperature! And will certainly disappear if you raise the temperature because the cavities vanish!

In the SAFIRE project, LENR transmutation occurs in tungsten in plasma at a temperature of 100,000C without the production of gamma. You have much to learn. Video available.
