Paragraph from book: Quote:....from EDISON HIS LIFE AND
BY FRANK LEWIS DYER
GENERAL COUNSEL FOR THE EDISON LABORATORY
AND ALLIED INTERESTS
..........EDISON had no sooner designed his dynamo in
1879 than he adopted the same form of machine
for use as a motor. The two are shown in the Scientific
American of October 18, 1879, and are alike, except
that the dynamo is vertical and the motor lies in a
horizontal position, the article remarking: "Its construction
differs but slightly from the electric generator."
This was but an evidence of his early appreciation
of the importance of electricity as a motive power;
but it will probably surprise many people to know
that he was the inventor of an electric motor before
he perfected his incandescent lamp. His interest in
the subject went back to his connection with General
Lefferts in the days of the evolution of the stock
ticker. While Edison was carrying on his shop at
Newark, New Jersey, there was considerable excitement
in electrical circles over the Payne motor, in
regard to the alleged performance of which Governor
Cornell of New York and other wealthy capitalists
were quite enthusiastic. Payne had a shop in Newark,
and in one small room was the motor, weighing perhaps
six hundred pounds. It was of circular form,
incased in iron, with the ends of several small magnets
sticking through the floor. A pulley and belt, con-
nected to a circular saw larger than the motor,
permitted large logs of oak timber to be sawed with ease
with the use of two small cells of battery. Edison's
friend, General Lefferts, had become excited and was
determined to invest a large sum of money in the
motor company, but knowing Edison's intimate
familiarity with all electrical subjects he was wise
enough to ask his young expert to go and see the
motor with him. At an appointed hour Edison went
to the office of the motor company and found there
the venerable Professor Morse, Governor Cornell,
General Lefferts, and many others who had been
invited to witness a performance of the motor. They
all proceeded to the room where the motor was at
work. Payne put a wire in the binding-post of the
battery, the motor started, and an assistant began
sawing a heavy oak log. It worked beautifully, and so
great was the power developed, apparently, from the
small battery, that Morse exclaimed: "I am thankful
that I have lived to see this day." But Edison
kept a close watch on the motor. The results were
so foreign to his experience that he knew there was
a trick in it. He soon discovered it. While holding
his hand on the frame of the motor he noticed a
tremble coincident with the exhaust of an engine
across the alleyway, and he then knew that the
power came from the engine by a belt under the floor,
shifted on and off by a magnet, the other magnets
being a blind. He whispered to the General to put
his hand on the frame of the motor, watch the
exhaust, and note the coincident tremor. The General
did so, and in about fifteen seconds he said: "Well,
Edison, I must go now. This thing is a fraud." And
thus he saved his money, although others not so
shrewdly advised were easily persuaded to invest by
such a demonstration.

- Missed it... hope they rerun it in the future and I am able to catch it
very well built... just can't imagine getting that type of performance from
roadster. Tesla would have approved, I think... he would have designed a
practical model probably? thanks Dave

The piece should be still up, but only for 24 or so more hours: its
a weekly. next/this week's will overtake last week's...
(There is an archive of past shows, but I have never tinkered
with it much.)
Electric motors have 'extreme' short term overload capability,
if the rest of the control gear/batteries are up to it.
teslamotors.com (I think) web site shoudl have more info.

- Unlike the mythical "Tesla car" the Tesla Motors vehicle is real
enough, obeys all known laws of physics, and uses today's technology.
The price shows it of course. If one belonged to the idle rich it would
be fun to own one but I suspect the battery life will be relatively
short in spite of their attempts at the most reliable design possible.
My friend who drove an EV-1 for a few years reported pretty continuous
battery problems in spite of water cooling on charge. In spite of that
he really hated to give it back when the contract was terminated but
didn't really complain because he understood the purpose of the project
and, as a GM executive, had participated in the program starting with
the Sun Racer which came before it
For those of you who aren't aware electric power for model airplanes
has really become a reality in the past few years. Even NiCd batteries
work pretty well and can be overloaded enough that their weight doesn't
hurt performance too much. With the newest Li Po cells the weight is
way down and, if you want to fork up the cash, you can get 1500 watt
brushless motors. That's enough power for a pretty good sized plane.
For myself I'm interested in the lightweight side of things and have
been playing with "park flyers", about 8 oz flying weight and up to
almost an hour flying time on 800 mAh LiPoly cells. The really extreme
small guys are down to flying weights of a few grams but my fingers are
too clumsy for that and I don't have an indoor place to fly.
I'm not aware of any suggestions by Tesla himself concerning
electric power for aircraft but it must have occurred to him. He was
probably too realistic in his understanding of battery technology of
