InterestingIn their release about the NexGen powder production line they state "While incorporating the NexGen improvements, it became clear that there were opportunities for further refinements with respect to our downstream powder process" and "the downstream changes that we have also incorporated into the process now allow for even further control over powder morphology, or more specifically, powder partical shape and distribution". So they have already included the new downstream refinements which further separates them from the competition but what are these refinements? I wonder if they relate to the work with HPQ and the nano-silicon reactor. The nano silicon reactor gives them smaller (nano) particles and they have been working on nanotubes etc. with the process. This would match with "particle shape and distribution".
