to add on, i randomly picked up an older issue of a UK car mag
to read while having dinner just now, and guess wad topic i
find?
someone ask if sharks have a skin like that... blah blah, u get the
idea, then why not use it for F1 cars.
the reply was that very simply, air n water are very different
fluids. what works for one doesn't necessary work for the other. If
it worked, then F1 teams would have used it a long time ago.
So not only is it not microscopic enuf, its also a different fluid
medium and thus unlikely to work. unlike vortex generators
afterall, which just control airflow over certain critical aero
components, and do not achieve the sharkskin effect.
