The URL below links to a clip of something called a "Vortex Vent" -- basically
a rotating nozzle that connected to a vacuum-source. The idea is that when the
air spins rapidly enough, it creates a mini-tornado that can actually create
suction from up to 10-feet away.
If this URL is split into 2 lines, you might have to recombine them in notepad
and then paste into your browser in order to see the clip.
This is similar to the technology that I have been experimenting with lately,
although I don't have a perfected model yet like the one in this clip.
