"...the F.O.I., Marcus Garvey, 'Nicky' Tesla; I shock you like an ill 'electric' field - Jay Electra..."

excerpts from: The Strange Life of Nikola Tesla
"There was another and still more important reason for my late awakening. In my
boyhood I suffered from a peculiar affliction due to the appearance of images, often
accompanied by strong flashes of light, which marred the sight of real objects and
interfered with my thoughts and action. They were pictures of things and scenes
which i had really seen, never of those imagined. When a word was spoken to me
the image of the object it designated would present itself vividly to my vision and
sometimes I was quite unable to distinguish weather what I saw was tangible or not.
This caused me great discomfort and anxiety."NIKOLA TESLA IS THE TRUE UNSUNG
PROPHET OF THE ELECTRIC AGE!;
without whom our radio, auto ignition,
telephone, alternating current power
generation and transmission, radio and
television would all have been impossible.
Yet his life and times have vanished largely
from public access."When I get an idea, I start at once building it up in my imagination. I change the
construction, make improvements and operate the device in my mind. It is
absolutely immaterial to me whether I run my turbine in thought or test it in my
shop. I even note if it is out of balance. There is no difference whatever; the results
are the same. In this way I am able to rapidly develop and perfect a conception
without touching anything. When I have gone so far as to embody in the invention
every possible improvement I can think of and see no fault anywhere, I put into
concrete form this final product of my brain. Invariably my device works as I
conceived that it should, and the experiment comes out exactly as I planned it. In
twenty years there has not been a single exception. Why should it be otherwise?" 
The Tesla coil is one of Nikola Tesla's most famous inventions. It is essentially a high-frequency air-core transformer. It takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage. Voltages can get to be well above 1,000,000 volts and are discharged in the form of electrical arcs. Tesla himself got arcs up to 100,000,000 volts, but I don't think that has been duplicated by anybody else. Tesla coils are unique in the fact that they create extremely powerful electrical fields. Large coils have been known to wirelessly light up florescent lights up to 50 feet away, and because of the fact that it is an electric field that goes directly into the light and doesn't use the electrodes, even burned-out florescent lights will glow.
