Inventor Frank Polifka calls his Windhexe machine "Tornado in a Can". It safely harnesses the enormous power of a funnel cloud in a small mechanical canister. The efficiency with which it can pulverize a wide array of items defies conventional physics and invites a new model to be constructed to explain how vortex energy operates.

What is it?

: "Whatever you put in the Windhexe β€” shoes, rocks, sludge, concrete, industrial waste β€” comes out the bottom as a superfine powder. It’s a clean way to dispose of almost anything safely and cheaply, because there are virtually no polluting emissions. Industrial scientists say its uses could be limited only by the imagination.

: "An upside-down cone just 8 feet tall, with no moving parts, it swiftly (and loudly) reduces pretty much anything to a powder of particles roughly a micron across β€” about 0.00004 of an inch, or one one-hundredth the width of a human hair."

: "The Windhexe generates so little heat that you can safely catch the resulting powder in the palm of your hand as it streams out the bottom." (MSNBC May 19, 2004)

How it Works

Compressed air is injected at the top through nozzles. Small deflection plates then force that air to flow in a counterclockwise direction, creating a miniature tornado in the funnel-shaped can. Using just a fraction of the energy employed by conventional crushers and dryers, the Windhexe breaks solid material down, increasing its surface area. (ref)

Directory:Inventors > Garage inventors - In garages, basements and even a Quonset hut, amazing science is happening without institutional or government funding. For example, the Directory:Tornado in a Can is a six' metal funnel supported by four legs, and as four jets around the rim of the funnel blow compressed air into it, a high-speed vortex is formed for pulverizing.
