Yeah... You have a point about how useful it might be (especially for a
Bay area pilot such as myself)...

Although - The tube flow is pressurized, so there's no reason that a
hirsch tube setup could be used as the preassurization mechanism for an
aircraft (assuming the structure can handle it... big assumption)...
The only question would be could you maintain a comfortable balance of
warm and cold air...

I dunno... Probably more effort than its worth, i'll agree, but its
still fun to think about.
