Well..from the shareholder letter it seems the reactors were idled so the only way they could have made samples where by batch..They need to be able to make those samples in the reactor or the previous samples are irrelevant as the reactor or flow reactor is the only way to mass produce.If you can demonstrate you can produce copious amounts of highly opitimized red and green...bingo..your potential partners will tick that off their list as completed.Im still at a loss as to why they idled the reactors as that is the only way true mass production can be achieved.Well that's past history so time to look forward and good to hear the reactors are fully functioning again.Just my thoughts
