To your last sentence; maybe....maybe not.
For all I know Dr.J is capable of printing-out 'SolarSheets' , not just cells. But the fact is that I don't really know, you don't really know & none of us really know the full extent of what's going on behind closed corporate doors, as might-well be expected in any start-up venture into a competitive tech landscape. I'm growing old just like the rest of you & QMCs' breakout can't come any2soon for me either, but until it does, I still appreciate steady advancements in the right direction & what little info QMC can safely release, as opposed to the tedious stealth we endured a few years ago.
QMC is still in-the-game....& consequently, so are we.
