In the following video, Melvin Miles states the following about boron (starting at around 15 mins):
"If you run it with boron, you already have boron on the surface. You have this B2O3 on the surface. It gets oxidized on the surface, so you already have the blocking oxide right at the beginning of the experiment. And so we saw excess heat with palladium boron in the first 57 hours. We could see the excess heat effect started off--not after a week or two weeks. It's within the first period of electrolysis. First two days, we started seeing excess heat." http://www.youtube.com/watch?v=j7ZM2z_fVcE I can tell you that crystals form on the electrodes and in the bottom of the cell in electrolysis with borax. They are pretty hard, requiring me to break up the crystals in the bottom of the jar to clean them out with a screw driver. Jack
