You're not getting the point. The "demonstrator" is nothing more than a small blimp. Been around for a hundred years.
If this thing would go to 65,000 ft., stay there for about a year or so, ON ITS OWN, then I would be more than a little excited. Right now, I'm pretty sure you can buy a scaled down version of what we saw at Radio Shack.
Sorry...
must be the season
