Yes, I've read a lot of stuff on Tesla. He was misunderstood and not given
the praise that he should have recieved. A true genius!

For example, most people say that Marconi invented the radio when in fact it
was Tesla.

Right on mikey. I have a lot of old Elec. Eng. texts and most of them
mention Steinmetz.

I suspect Marconi got the credit because he perfected the coherer, a sort
of liquid diode type of thing to detect RF.

I saw a documentary on Tesla some months ago.......If I recall
correctly, it was stated that Tesla was to receive a royalty of
something like $2 for every horsepower of electrical motors produced
(by Westinghouse or some other firm)......I think the contract was
changed or never signed......If it was true and ever took place, the
wealth of Tesla would probably make Bill Gates look like a pauper in
comparison........

PS and FWIW Another recommended Tesla Tome is "The Inventions, Researches
and Writings of Nikola Tesla". Very technical; contains a lot of papers and
addresses to various intellectual bodies of the time. A hard read, though,
because a lot of the terminology used is different from that of today.

(attributes got messed up a bit I think there, was that Bob's
comment?)

Coherers are not electrolytic, they use powdered metal filings which
stick together (cohere) under the influence of applied rf energy.

There is good reason to believe that while marconi developed the
coherer into a relatively well-funtioning product, he did not
invent it.

Reginald Fessenden invented the electrolytic detector which is
probably the 'liquid diode' mentioned above.

My mistake Jim. The key point is that Marconi developed a way to detect
(demod) RF whereas Tesla may have been among the first to generate RF. I
think it is safe to say Marconi perfected wireless transmission of telegraph
signals. Thanx for the correction on Fessenden's liquid diode. I recall
reading that early watt-hour meters were electrolytic devices. Not sure how
they worked, though. Maybe someone can help.

I may not remeber this 100% correctly, but I seem to recall reading
that at one point, one type of meter was a sort of electrolytic cell
with copper bars in it, in which as the customer drew power from the
line, it would cause material to be plated onto the copper bars.
Periodically, the "meter reader" would drop by and weigh the rods to
determine how much to bill the customer. Drawing a blank on the
details and source, so this could be all wrong. G

I've heard of such a thing.

A lot of old Sony pro video gear had hour
meters that worked on the same principle.
A little glass cartridge about the size of
a 3AG fuse with a bead of metal that would
move over time when current was applied.
They were good for 1000 hours and then could
be flipped around for another 1000 hours.

Ah, now *that* was edison, of course. He could not make any
kind of watt-hour meter that depended on any AC effects of course.
So he invented and used the electrolytic type. They had to
be kept from freezing incidently.

Jagadish Chandra Bose, an Indian physicist, has been credited with
wireless signaling well before Marconi. He demonstrated signaling and
remote control with microwaves in the 1896. He was the first to
use a semiconductor detector, and invented many devices used in microwave
communication. See http://www.calcuttaweb.com/people/jcbose.shtml

This sounds believable -- at least for a DC supply. AC would
plate things back and forth at 1/120th second intrevals (here in the
USA), or at 1/100th second intervals in the UK.

Wasn't it Westinghouse who was the proponent of the DC power
distribution system, and Tesla the proponent of AC distribution?

And, as another followup mentioned, there were tiny
hours-of-operation meters which worked on this principle -- back in the
1970s, IIRC. I had some of them at work, for certain projects.

Enjoy,

Nah, Edison was DC. Westinghouse bought rights to Tesla's patents and
employed him.

I recall soon after Tesla arrived, he was digging ditches for Edison; I
don't remember if he did anything technical. I know he didn't like Tom and
his big interest in DC. g

Ah, no. The big fight was Edison against everyone else.

Edison wire lower manhattan for DC distribution early on and
continually pushed against AC.

Eventually Edison Electric was bought out by westinghouse

Edison for DC power. Big fights with Tesla, he actually employed Tesla
at one stage, IIRC, to do some work on synchronising DC gen sets.

According to what I have read Westinghouse dealt with Tesla in a much
fairer way compared to J.P. Morgan.

Unfortunately a good deal of Tesla's financial problems seem to be of
his own doing.

IMO, It was a *huge mistake* for Tesla to work with J.P. Morgan on
Wardenclyffe. This following link explains why.

http://en.wikipedia.org/wiki/Wardenclyffe_Tower

I believe the Wardenclyffe site should be preserved and the tower
rebuilt. That it has not been done already is IMO quite sad.

Very early on Westinghouse understood the huge advantage of Tesla's
polyphase AC system.

Westinghouse was awarded the contract for turning Niagara Falls into a
major AC power provider based on Tesla's patents.

It was Edison who pushed DC power and portrayed AC power as very
dangerous.

This is my only book about Tesla. If you know already some, maybe it

It's focus is more on the commercial side of Tesla. Not so much focus
that it gets boaring (I'm not at all a salesman), but just enough to see
what he made wrong and how he got ripped every now and then. Still his
inventions and his life are the biggest part of the book.
Really nice to read.

And yet it was many years before AC would become popular as a use for

American Marconi ceased to exist after ww1. This was basically
by agreement of all parties concerned. The end result of this
was RCA, a corporation that was conceived of and created pretty
much out of whole cloth by US government regulators.

The point was that at the time, the US had no reliable means
to communicate with europe besides some sketchy, vulnerable
translantic cables. Other than, the alexanderson alternators
that were owned by marconi co.

Foreign ownership of infrastructure like that was unacceptable
to the government. But IIRC everyone came away from the deal
happy.

Image recognition that kind a thing when the computer calculates up a

AFAIK, a charged-particle beam weapon that could also transmit power from
LEO solar farm high above stationary earth to a ground based collector is
one other likely scenario.

Actually, the sun emits lots of radio waves ... and you

Even better, usually, is a tuned circuit with tuned antenna
for 60 or 120 Hz (probably mostly US technology only).
