the reason "ram air" doesn't "work" is that it makes maybe .01 bar of
extra pressure, and then only at high speed.

the air plate issue is more one of turbulence, I believe.  it is raised
by a certain mass of air moving through the cone, not by "sucking" or
"blowing", which are of course the same thing, pressure differences
between two places.

hmmmm, not sure this reply will pass the censors!
