He mentions about having a mylar belt spanning a valley. That would be a good idea except for the noise the belt will emit. People now complain about the noise from a wind turbine -- the noise from a belt across a valley would be much worse.

Does look neat. I think of the sound made by my nylon ratchet straps on a trailerload of stuff if I forget to put some turns in the strap.. you'd think there was a giant hummingbird behind me (c: From: Craig diese...@pisquared.net To: Mercedes Discussion List mercedes@okiebenz.com Sent: Saturday, August 17, 2013 2:31 PM Subject: Re: [MBZ] OT: Wind Power from aerodynamic flutter On Sat, 17 Aug 2013 13:22:57 -0400 Mitch Haley m...@voyager.net wrote: http://video.popularmechanics.com/services/player/bcpid1214137061?bctid=1233395616 Veeeyyy Intesting.

Interesting. The simplicity is elegant! I would expect material failure (fatigue) would be the main problem. It may be possible to use there in out-of-phase pairs to minimize (cancel) the far field noise/acoustic effects. -Original Message- From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Mitch Haley Sent: Saturday, August 17, 2013 1:23 PM To: Mercedes Discussion List Subject: [MBZ] OT: Wind Power from aerodynamic flutter http://video.popularmechanics.com/services/player/bcpid1214137061?bctid=1233 395616 ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

It may be possible to use there in out-of-phase pairs to minimize (cancel) the far field noise/acoustic effects. That is a good idea. One could vary the tension of one of a pair to bring it to resonance with the other and to keep it 180 degrees out of phase. That, however, greatly complicates the simple solution.
