In some ways, it looks like a hop, skip, and jump from my plumbing pipe pulsejets. It would be neat to mount/screw a valveless pulsejet directly on top of a propane canister though and really impress your friends with a deafening brazing, pipe-sweating soldering tool.
Notice how similar his home-made device resembles my pipe pulsejets. Certainly, you could improve on his design and really blowtorch something from 6 feet away with a large tank of propane.
