How enlightening an answer. When unable to answer a question, turn it around and hope no one notices.

"Trank" is absolutely right. All you, and others, do is throw out possibilities and make it look like it's a plus for ZEN. The only way any of these potential end users matter is if ZEN can prove it can produce reliably consistent graphite. If and when that happens, it won't matter what uses you've discussed, because all of ZEN's graphite will be spoken for, or ZEN will be bought out. Until that day, however, you can pump all you want, but it means squat.
