I have a lapsed background in EE and am not a scientist.
However, to be prudent, I would not choose Mizuno's R20 experiment as the first candidate for the Google team for at least 3 reasons :
1) R20 needs to be successfuly replicated to be sure it is a real candidate for replication !
Even if I believe it works, this has no bearing on the choice to advise.
The situation would be totally different if, after say a few successful replications, the LENR community was still desperate to publicize these results in the mainstream media and/or academia.
2) As some have already said in this thread, it is better to start with basics.
R20 is definitively not one (see #1).
Ascoli65 proposes the 1992 F&P experiment says it has already been replicated : maybe it is a good candidate ?
Whatever the experiment, if Google helps publicize a replication, the impact will be absolutely huge.
3) Everybody on this forum seems to believe that Google will succeed in replicating the best choice made by this forum members.
However, Google team track record is not really good in this matter as they failed to replicate some known to be replicable experiments.
Do you really want a second article in Nature describing another failed CF experiment ?
Can you imagine the impact ?
Would that mean the end of all further attempts in the LENR field, namely in terms of investment ?
If Google fails again to replicate a known to be replicable experiment, that would probably mean they are not good at that ...
