Stan and I funded the first phase of the work ourselves. It was secret.
I have had this view of the optimization of the electrode design for a long time. Historically we went through various phases in the work and eventually worked on large sheets - very large sheets - of palladium.
It doesn't matter whether you can or cannot achieve high temperature superconductivity or fuel cells, they will always be on the list because if you could achieve them they would be extremely valuable.
