The article mentions the upper back fairing of a motoGP racer but then blows off the idea for a cyclist because they might get too hot? I've always wondered why road cyclists don't ditch their frame mounted (and drag inducing) water bottles for a camelback. The original camelback was slim and I can't imagine it added any drag seeing as it sits on the back of the cyclist. Plus it has the advantage of allowing the cyclist to maintain a better cylcing position without having to reach down for a bottle.
But then again if roadies were really all that concerned about aero and efficiency they'd switch to recumbent bikes...
In pro cycling it's actually forbidden to have aero fairings on your bike. During the Armstrong years there has been a controversy about the placement of his radio on his back during time trials that would incur fairing.
