In this last day of suggestions to the Team Google, I'd like to stress that a mandatory goal of the next investigation on CF is to avoid any negative outcome. A negative is not useful to anybody. Reporting a failure to measure any excess heat will be criticized by both the mainstream scientists, which could say that there was no need to waste money and time on this largely predictable outcome, and by the LENR fans, who will find many reasons to justify the negatives, like, for example, those reported in the recent ArXiv paper (1): "… possible reasons for negative results of 'cold fusion' experiments published recently by the Google-organized scientific group are given."
If Team Google is aimed at obtaining some excess heat, they are going to dig the umpteenth hole in the water and their work will be basically ignored by mainstream scientists and LENR fans and, this time, also by Nature.
It's necessary that their next paper begins with a positive declaration, something like: "We have succeeded in replicating the fundamental phenomenon observed by Fleischmann and Pons since 1986 and which led the research in Cold Fusion for the next decades. This phenomenon, called "positive feedback", has been largely discussed in many of their articles and is well documented in their 1992 video, which clearly show its dramatic effects on the electrolyte. We have been able to accurately replicate this phenomenon at will on a regular basis and we are now able to explain all its characteristics and the real source of the excess heat claimed by the 2 pioneers of Cold Fusion".
If Team Google wants to attract the attention of the mainstream science and avoid harsh criticisms from both CF supporters and deniers, they should carefully select the goal of their next study in order to be sure that it will be successfully achieved, that is that they will get a positive outcome, replicable by any other laboratory. IMO, the only goal which offers a 100% guarantee that will be achieved is the replication of the "positive feedback" phenomenon documented in the F&P video of the "1992 boil-off experiment".
