What they're not addressing, is the fact that, base pressure is ruled by the pressure at the separation line.
The wake remains the full frontal area of the rig, and its wake pressure the same. They've done nothing to alter that fact.
Altering the shape of the wake does nothing to address the pressure, and could actually exacerbate drag by introducing velocities and vorticity which otherwise would not exist. It can be worse than the turbulence they're trying to abate.
What we're targeting is, a controlled deceleration of the air, while rebuilding static pressure, the domain of a streamlined body.
Until they present a more complete argument, their claims remain quite dubious and half-baked.
A simple, sexy, falsehood may sell better than a tedious, complicated truth, but at the end of the day, physics and reality may spoil the party.
