If I had to chose today, #1 would be Takahashi's (Technova/Nissan & Tohoku/Kobe/Kyushu/Nagoya Universities) group. One does not have to be skilled in the lab to understand why. They have many on their team, and replicated each other. That is almost as good as a high impact journal peer review. A huge bonus, is that their team requested their work be replicated by others, and put out a rough blueprint to follow. I do believe also, that they would be open to any assistance requested by Team Google? And if it were necessary to keep that assistance quiet, there none better at keeping a secret than the Japanese.
Then, how could one beat Forsley/Mossier-Boss, and their co-dep work? It has been around for many years, and peer reviewed. So confident are they about their results, they are disseminating a kit as part of the STEM program. Better yet, GEC and NASA are incorporating the system into their hybrid space power generation system. That relationship has been ongoing almost 2 years now, at NASA's Plum Brook station near Cleveland, and it still appears to be progressing along well. How is that for confirmation of it's feasibilty? As with Takahashi; Larry, and Pam would I think be more than happy to help.
Not knocking Mizuno/Rothwell, but at this point that is an unknown. If Google had to start tomorrow to lay the ground work for the next research project, at least they have two other good choices already in hand.
But we are still not finished. I am still interested in what Russia has to offer? There has been so much quality research going on there for decades, much of it with positive results. I would think if they took their 3 best, their "list" for Google, would rival our 3. SERGEI ?
Let’s hope Google throws caution
to the wind and goes for all of the
