That's a false argument. Who claimed scaling up from batch and flow are the same? Nobody I've seen, and certainly not me. What is the same is that both Dow and AMTRON were convinced that scale-up will work. Apparently it didn't for Dow, so unless you think the folks at Dow didn't do any diligence or are just stupid, you have to acknowledge that things don't always play out as expected in chemical engineering. That's the point - not that batch and flow are the same.

Maybe scaling is a lot easier in flow. Maybe QDs for solar don't need to be as perfect as for displays. Hopefully everything will go as planned. It's certainly possible. Notwithstanding, at this point, making additional reactors is not proof of scale. It's proof of making additional reactors.

The exact same arguments apply to making QDSC with high-speed R2R printing. Even if they are successful in scaling up QD production with no problems, it's still a significant challenge to make R2R QD solar cells, no? Has any company ever successfully done it at scale? I believe QMC has made QDSC in the lab, but I don't see where they have claimed to have even tried it R2R, let alone at high speeds, and there is nothing I see in the financials that suggests they have spent a material amount of money working on it.

Revenue from royalties and products is proof of scale. Everything else is just talk.
