I wonder if that's why my tailpipe is located kind of high:
I read the article, and it does not disagree with James and Piwoslaw.
I really can't imagine a method of compressing air that's more efficient than collecting it from aerodynamic high-pressure zones of the vehicle, and Piwoslaw spells out in post five why that's almost certain to fail.
However, if they can reduce the air requirements with pulsed blowing as they mention, it might work out.
