Wind vortex

How cool is that?

Mechanical engineering seniors (l-r, back row) Alexander Everett, Alex Kalitzki and Eric Havran successfully demonstrate their vortex ring generator to an unidentified classmate during the mechanical engineering department's first Design Expo Dec. 7 in Howe Hall. The team designed this one as an attention-grabber -- similar to a promotional searchlight -- for use in advertising. Similar devices reportedly have been used in spraying orchards for insects or (in an industrial application) to mix fluids. The "ring guys" were one of 56 student teams who shared a prototype at the expo. Photo by Leah Hansen.
