I think what you're overlooking here is that the (100 - 59.3 = 40.7)% (see, there's an equation for you!) isn't all, or even mostly, going into drag. It's just passing through, uncaptured. Which, when you think of it, is pretty much common sense, since if a turbine captured all the energy from wind, the air would stop moving, and it would be perfectly calm directly behind the turbine.
Considering the above, me thinks it's time you put all that education to use and show some mad math skills.

Some thing along these lines?

Calculating the Coefficient of Drag - Urbee Example | Sustainability Workshop

The formula would need to be added to and modified a bit, right?

Prove to us that you can make this (compact turbine generator) mathematically work.

Maybe this is why such things are called "proofs".
