Nice, Dutchy. I've been thinking about making something similar and thinking about the design. I would like one a little longer but I wonder if it would really suck in that much from the far end so i was considering putting a grill or something at the hose end at least that would help extend how much air has to come in along its length and especially at the opposite end.
