G,
Think of the Japanese public transportation systems like rail,fast speed train,buses etc.and you will see the big picture.
By the way,here is from the BGU earlier news release:
Dr. Oren Regev, and Dr. Ilan Pribar of the Department of Chemical Engineering at BGU, stated “Zenyatta’s purified graphite material was tested by our R&D team on dispersion and application for composite property enhancement on drug delivery and hydrogen storage devices. BGU regularly uses various types of commercially available natural flake graphite but found Albany graphite to exfoliate under sonication much easier and with higher yields of graphene nano-particles than any other natural graphite types that we have tried.
Typically,anything involved with drug testing etc. will take forever to be proven and verified for it,s effectiveness.
