Very interesting! How does the vacuum come about? One of the reasons I actually wanted to serial-connect them was because I'd seen your room...

faithless Reviewed by faithless on . Connect 2 COOLTUBES Design Plan My plan involves 3 exhaust fans. No.1 at bottom left sucking in cold air, no. 2 is also an exhaust sucking air out of the first cooltube into the second. No.3 is another exaust sucking the combined air out of the two lamps and out of the room. Does that work? Much obliged for pointers, want to start this in 2 weeks time. :D Rating: 5
