According to the newspaper article I read, the proposed fiber is a "tape" roughly three feet wide and a few thou thick. A flat ribbon is aerodynamically unstable and will vibrate axially in any wind. This thing would seem to be the ultimate Tacoma Narrows Bridge. Just my first impression. The problem with the Tacoma bridge was that the materials couldn't handle the flexing. Lots of materials are designed to vibrate - saxophone reeds, guitar strings, etc. So what would the pitch of this critter be, and how many Db?
