"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"

Martin Fleischmann is describing the optimization of the design of an electrode, which is a gadget used to perform electrical power. He is recommending that he has had this view of the optimization for a long time, and that the work has gone through numerous stages. He mentions that ultimately they worked on large sheets of palladium, which is a metal that is used in electroplating and in the production of batteries. This recommends that the optimization of the electrode design was a long and complex procedure, which using palladium was an important part of the process. This quote highlights the significance of the optimization of the electrode design, and the devotion of the group to guarantee that the design was as efficient as possible.
