The Owen magnettic was not really a generator/motor set up.  What they did
was
to use electricity as sort of a clutch and torque converter.  That is-the
gas
engine was attached to the "field" and the drive shaft to the "armature",
then
back at the rear end was a second similar set up.  When the gas engine
turned
faster then the drive shaft, it generated electricity which provided power
to
the second "motor".  As the drive shaft speed matched the engine speed, the
system stopped generating power and essentially became a one to one match.

Interesting idea.  Too bad it didn't work out.

Old Doctor Porsche seemed to have loved gas-electric drive.  He built lots
of
cars and truck using it, but the most outstanding examples of his work was a
World War I artillary tractor for the Austrian-Hungarian army and his World
War "Elefant" using diesel electric drive.  Porsche, as we all know (wink)
was
from Czechoslovakia and worked for a time under Hans Ledwinka (the designer
of
the Tatra).

Jan Eyerman- who loves his Prius almost as much as he loves his Hillmans!

It's actually a pretty old idea: using an internal combustion engine to
power a generator to drive one or more electric motors. The pre-WW1 Owen
Magnetic (no relation to me AFAIK) had a generator/motor in line with
its engine in lieu of a clutch and gearbox. The Lohner-Porsches of
around the same time, designed by Dr. Ferdinand of course, used a
generator to drive four motors, one integral with each wheel (lots of
unsprung weight there, but they hadn't started worrying about that yet).
The downfall of these designs was the primitive state of gasoline
engines, generators, and electric motors, which translated into
humongous weight and a lot of wasted energy. Modern hybrids, such as
those from Toyota and Honda, benefit from light, efficient versions of
all these components. Their operating strategies vary, but basically
they use the engine by itself sometimes, the motor by itself sometimes,
both when they're needed. The engine never idles, but shuts off at
stops, and is quietly and unobtrusively restarted when the pedal is
pressed. I haven't driven one, but those who have generally find it
rather charming.
