Alan Smith the walls of the transparent tube look dusty, were you able to see it up close enough to tell if these dusts or specks were inside or outside the tube? Just curious due to the idea of dusty plasma that George Egely uses to talk about.
They are probably dusty both sides. This is not dusty plasma though, but the specks inside are probably catalyst particles ejected from inside the anode cup. I worked out what that was, but as I am NDA'd I couldn't possibly comment.
The Blower is not included in the COP calculations AFAIK (I am still waiting to see the data-set) but at they pointed out, it is a much bigger system than they really need.
