Not at all. A perpetual motion machine does work without an energy
source, while my device uses the wind created by the moving vehicle as
its energy source.

It is as accurate as it needs to be in my case.

The energy put out by the engine is not wasted energy, if that's what
you're saying. It is used to move the vehicle. The turbulence created
by the movement of the vehicle through the air is what's wasted. My
device harnesses some of it to take some of the load off the vehicle
engine.

No. If my estimates are correct, my device will not reduce the
"turbulent dissipation of energy" - in fact, it adds to it. "Reducing
drag" is not the same thing as "turbulent dissipation of the engine's
energy in air". Reducing the aerodynamic drag coefficient lowers such
"turbulent dissipation...of...energy ", but I am not suggesting such a
reduction. Vehicles today are designed with the lowest aerodynamic
drag possible consistent with their purpose.

My device adds drag, and thus, turbulence, but calculations show that
it is less than the energy used by the vehicle engine to provide 4 to
30 hp to turn its alternator. Please search for my posts in this ng
for the topic, "Drag Coefficient of Box Lights Atop a Police Cruiser"
and read how I arrived at my estimated 10% fuel savings.

Not so. Inventors I know relate how it is next to impossible to sell
something to the manufacturing industry. One of the greatest salesmen
of all time said he tried and tried to sell several inventions that
later turned out profitable or were accepted as optional or standard
equipment to auto company buyers, to no avail. It is really stupid to
have company reps who know only about the current bottom line and have
no vision at all or knowledge of physics. That's why we don't have
flying cars yet, and why the government has to force auto companies to
improve consumer safety. Don't you read Dilbert?
