Dr. Black, Namaska. Upon further re-VIEW I saw it a NEW and realized I had not watched the video. During which the physicist says "graphene." I was watching the video a second time to be sure I understood the use of ethanol as a battery, which I did on the second try; but what jumped out then was to go back a third time and listen to what that material was they said they were trying to make when they accidentally discovered this application of chemistry.
Graphene. I had heard of it before and thought, "Woh!" But as people keep working to produce the material, I know I have heard of other accidents like this along the way - and wish I could remember those like I will certainly remember this one thanks to the discussion.
You are definitely right about Greeks getting fat and lazy with their knowledge. Grapes got nothing on electrical chemistry.
