Only 7 million oz of palladium mined worldwide yearly mostly from Russia. (They will not sale any, if this thing works), But even if cold fusion works we simply do not have the quantity needed to take it to mainstream like cars, where something like 100 million oz would be needed annually, (3 little plate like you see in the demo would be needed to replace one car battery only.) and cars are only one of the many area of energy needs.
The pentagon might be interested, but they will not tell us anything in our life time either way.
