To answer your first question RW, Ae said that Zenyatta had been approached by at least two nuclear facilities but that they were lower priroty because of the lead time...can take 5 years or longer (however because the graphite is so spectacular that time could be reduced).
Secondly, Yamashita will be covering S Korea but there aren't as many companies in S Korea as Japan but a few big ones.....he mentioned that they met with some when they were in Tokyo earlier this year.
