A very interesting subject in my opinion Ice Czar.
I started a thread about this but cant find it anywhere.
Heat is about moving atoms; the hotter a solid the faster the atoms vibrate, or something like?
This means that the electrons are also much more excited in a hotter solid.
There are some people that believe removing these more excited electrons and replacing them with less excited ones, using the method you describe, will have a further cooling effect.
So:
Quiet airflow.
Boundry layer negated.
Possible extra cooling due to electron replacement.
The downside is 30 000 Volts.
But hey; Thats whats in your CRT monitor, and no-ones scared of touching their monitors!
