i've been watching this board and the company blog for a while now and i must say that the recent pics of the tubes and the potential product is significant....having some experience with diamond drill bit manufacture ( in my long lost youth ) led me to invest in this concept after reading mr. snappers profile....my opinion; huge potential....however, i am a bit concerned about the mention of "graphene" as this material is getting widespread play and script on the net as the next electronic panacea...2nd opinion; look for the " tubes " to be much more massive in the future.....possibly machined from pure graphite themselves... electical magnetic induction has been around for a long time and it seems resonable that these folks will reach the objective goal.....its a longshot, but im in for the long haul...greater the risk, the greater the reward.....
