"Patterson claims his invention can triple mileage, all other factors remaining the same. His associate, also present, vouched for the claims and shared a few anecdotal stories in private. He said that the vortex went nearly 100 feet in front of the van, and that he could effect a small trailer on a car in front of him by steering left and right. He also said that when he passed a semi truck that the normal grabbing of the vehicle in the semi's wake was absent.
"Patterson described unusual phenomenon he as observed while driving a vehicle thus fitted. 'We watched flies on the hood stay in place until we were traveling over 60 mph. Streamers on the surface of the vehicle stand perpendicular, rather than parallel to the vehicle.'"
I haven't seen a test claiming exceptional mileage that could be in any way called rigorous, and those that claim modest gains, one suspects could be duplicated by normal steady speed highway driving in those vehicles with conventional aerodynamic improvements, i.e. tailgate deflectors, spoilers or vortex/turbulation devices.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
