Anon - If you can get your backwards windtamer (tamerwind? rematdniw?) to work, God Bless You. OR, you can just issue press releases and and tell everyone that it works... Nahhh. No one would ever do that! LOL.
Seriously, though, I think the Penn State professor that WindTamer hired was an expert in air flow. Send her an e-mail - ya never know.
To make a long story, short Mr. Brock designed a backwards parachute. Just work on the pivot point orientation and now you got something there bucko, it will properly use the venturi effect to break the Betz limit with.
