Not sure where you have been there was a verification test a longtime ago which was press released and a video interview that followed. The system worked but there were still wrinkles that needed to be worked out including some damaged parts from shipping to the varification point. No date of when the next varification test would happen. Stay tuned, so far no cost to HPQ as the system has not been verified as per the agreement. Still in the game though.
But let's stay focused on getting the Pilot Plant verified and producing product without any squirrels or shinny objects distracting from the goal.
