I understand there exists an effect possible for submarines, one which creates
a gaseous volume around the submarine, and insulates the submarine surface
from water with a thin layer of a gas (air? water vapour?), thus allowing for
much higher speeds when submerged - even rivalling surface ship speeds. Since
this miltech apparently belongs to the cutting edge, I have found very few
refs to it in the on- and offline literature.
