first hand? no, but know what I would works b/c of the turbulent effect...right?

the turbulent boundary layer is able to remain attached to the surface of the ball much longer than a laminar boundary and so creates a narrower, low pressure, wake and hence less pressure drag. The reduction in pressure drag causes the ball to travel further.
No. They only proved that 100 lb of extra weight has minimal effect on a car already in motion. They deliberately (and rightly, for the experiment) ignored the fuel used to accelerate the extra mass.

The heavier car got a little bit better mileage b/c of the momentum of extra weight...but the v6 on the Taurus', acceleration would not be effected by the weight..

thanks for the useful info, all youze...I know its real...haha

bTW, if the thing improves the mileage, but it costs money, doesn't actually mean it's useless...b/c it could also be improving the resistance to wear and tear, right?

)**most things aren't practical for any and everybody...but they would be nice, and would be helping
