Abstract
The invention comprises magnus tubes mounted adjacent to or imbedded in the orthogonal edges of a vehicle such as a semi-trailer, these tubes preferably being interengaged, for concomitant rotation and having a motive force such as a motor to simultaneously drive the tubes to expedite laminar flow of air around the edges of the wall in question as the vehicle moves, it being preferred that the motive force be reversible to invest the magnus tube with an additional braking force.
