I won't post this Yoututbe video since it's off-topic but it's findable;
He describes plasma windows (for the muzzle of a rail gun), and towers that are a hollow tube supported by the flow of plasma dragging the tube upward.
I guess I'm a fan of Isaac Arthur, and plasma.

5% mpg on an 18-wheeler is worth going after.If the device can mimic a VG it could help mitigate some of the damage from crosswind separation.
*The effect would have to be like an optimized VG.
*The system would have to detect the apparent wind.
*Then 'position' the effect as a function of the apparent wind.
*The effect would have to modulate as a function of angle of attack and boundary layer thickness.
*With something like a scanivalve,cited laterally,where the mean flow intensity could be identified,this information fed to a CPU could interrogate a RAM look up menu and choose the best solution for the location,frequency,and amplitude of the effect based upon prior lab testing parameters programmed into the RAM.
*There wouldn't be a drag penalty for 'physical' VGs hard mounted at the nose.
