The sparking would have stopped after an equilibrium was reached. The
investors thought that consumption metering would be a problem, so
financing was stopped.

======================================
As early as 1892, Nikola Tesla created a basic design for radio. On
November 8, 1898 he patented a radio controlled robot-boat. Tesla used
this boat which was controlled by radio waves in the Electrical
Exhibition in 1898, Madison Square Garden.

I wonder how Tesla's work would have been different if his first great
rivalry had been with Marconi rather than Edison.


It was. There were really bad irregularities at the patent office.
Marconi had connections. Roughly forty years alter, thing were turned
around.

===============================================
A majority of the Court found, after tracing the lineage of radio
through Maxwell, Hertz, Lodge, Tesla, and Crookes, the basic Marconi
patent (No. 763,772, filed Nov. 1900) used nothing not already included
in Tesla's earlier patent No. 645,576 (filed Sept. 1897), except for the
presence in Marconi's design of an inductively tuneable antenna. (And
the antenna element under discussion-Lodge's patent, No. 609,104-was
bought from Lodge by Marconi.) The Court went on to note that Stone's
radio patent (No. 714,756) completely anticipated Marconi's, antenna
included. Stone, by the way, had always credited Tesla with the first
basic, workable design, saying of his own patent it was "practically the
same as that employed by Tesla" –but with the valuable refinements of a
tuneable antenna and design adjustments to "swamp" parasitic
oscillations in the transmitter.

Nikola Tesla (1856-1943) was the genius who lit the world,
whose discoveries in the field of alternating polyphase current
electricity advanced the United States and the rest of the world
into the modern industrial era.

Nikola Tesla had 700 patents in the US and Europe. Tesla's
discoveries include the Tesla Coil, fluorescent light,
Tesla Statue wireless transmission of electrical energy,
radio, remote control, discovery of cosmic radio waves
and use of ionosphere for scientific purposes.

The patent process was and still is rife with loopholes that
almost encourage abuse.

A.G. Bell beat Elisha Gray (who ironically founded Western
Electric and ran it during the rise of AT&T) to the patent on the
telephone through a technicality.

Gray actually had a working model first. And had the first filing.

Bell's project borrowed liberally from Gray.

(When I worked at AT&T, it was a cardinal sin to mention Gray's
name. We were all shown "The Alexander Graham Bell Story." A film
with huge historical inaccuracies regarding the invention of the
telephone. A film for which Alexander Graham Bell's daughter, Mrs.
Gilbert Grosvenor, had official script approval. The film was also
funded with huge help from AT&T.)

Vladimir Zworykin had actually visited Philo Farnsworth' lab and
translated whole technologies to his own Sarnoff funded project for
the development of Television. And with the aid of Sarnoff's
lawyers, landed the patent.

As with Tesla, Farnsworth's estate was eventually vindicated by
the courts, and Farnsworth was posthumously named the inventor of
Television.

Don't forget Nathan Stubblefield, and his wireless telephone.
