Dimples

Just watched this weeks episode of
mythbusters and got a 10% improvement in
gas mileage by putting (golf-ball like)
dimples in the car

I'm imagining all sorts of areas that
might benefit from this unexpected
result: windturbines, waterturbines and
ceiling fans more efficient

  Since, for the devices you mention, you would need
the opposite effect I take it you would be adding bumps,
instead of "dimples".

  Luck;

Based on the experiment and some

say no.

Unless I am misunderstanding your
question.
