	Nikola Tesla's Coil
		The Tesla Coil is an air-core transformer with primary and secondary coils tuned to resonate.
		The Tesla Coil consists of a vibrator or transformer (parts A and B in the Diagram), two (2) high-voltage capacitors (H), a primary (D), and a secondary (E) connected to a ball terminal or antenna (G).
		The secondary (or secondary coil) is a cone-shaped coil.

	PowerPedia:Tesla coil - PESWiki
		Tesla logged in his diary on January 2, 1900 that a separate resonance transformer tuned to the same high frequency as a larger high-voltage resonance transformer (which acted as a transmitter) received energy from the larger coil, one of many demonstrations of the wireless transmission of electrical energy.
		Tesla coils' outer conducting surfaces, which are charged to a high potential, have large radii of curvature to minimise leakage of the oscillating charges through corona discharges or sparks.
		Later coils consist of a primary tank circuit, which is a series LC circuit composed of a high voltage capacitor, spark gap, and primary coil; and the secondary LC circuit, a series resonant circuit consisting of the secondary coil and the toroid.

	Tesla_coil_intro
		This resonance occurs between the inductance of the coil and the capacitance of a rounded metal object (typically a donut shaped toroid) and a very high voltage results in streamers directly into the air or sparks to nearby objects.
		The largest spark that I am aware of at 325 ft was from a 5 MV Marx generator, not a Tesla coil.
		If made specifically for this coil then 4 or 5 copper pipes could have been bolted on to a flat section of acrylic or other insulator as the geometry of the cylindrical setup is trickier.

	PBS: Tesla - Master of Lightning: The Tesla Coil
		None of the circuit's typical components were unknown at the time, but its design and operation together achieved unique results—not the least because of Tesla's masterful refinements in construction of key elements, most particularly of a special transformer, or coil, which is at the heart of the circuit's performance.
		If a coil and condenser are sized and selected to act with exactly opposite timing—with voltage peaking in the coil just as it reaches a minimum in the capacitor—then the circuit may never reach an electrically quiet, stable state.
		Tesla himself used larger or smaller versions of his invention to investigate fluorescence, x-rays, radio, wireless power, biological effects, and even the electromagnetic nature of the earth and its atmosphere.

		Tesla was hired by firms in Germany and France to improve their direct current (DC) generation facilities, but neither was interested in his radical AC designs.
		Tesla spent a year at the site in Colorado testing and experimenting with his "resonate transformer." The results convinced him it was possible to send power through the air.

	What Is A Tesla Coil
		A Tesla coil is a high voltage, high frequency transformer that can produce arcs of lightning.
		Tesla coils are mostly built by high-voltage enthusiasts as a hobby.

	Nikola Tesla \| TFCBooks Feedline Newsletter Articles
		Nikola Tesla's principle contribution to the early history of wireless communications was his improvement of existing radio frequency current sources and primitive receivers through the introduction of coupled tuned circuits.
		The feedback loop that Tesla used in some of his 1899 wireless receivers to increase front-end sensitivity may be viewed as a forerunner of the regenerative receiver circuit.
		Tesla's 1899 investigations in the area of wireless propagation involved the simultaneous transmission of two or more electric waves of different frequency which led to the production of the ball lightning phenomenon.

	Altair - Nikola Tesla and How to Make a Tesla Coil
		The Tesla Coil was delightfully awe inspiring, with its shattering roar and streamers of purple fire writhing in the air.
		In high power Tesla coils, the RF energy in the primary may cause the gap to continue conducting RF after the capacitor is discharged, which depletes the energy from the primary-secondary system.
		Primary coils spirally wound in the shape of an inverted cone allow the coupling to be adjusted by raising or lowering the secondary.

	PowerLabs Twin Tesla Coil!
		Both coils wound and varnished, with their copper ground straps on place (not really visible due to poor lighting on the picture) and their space-wound top inch, which will be used for further distancing the toroid from the strike rail.
		For the final version of the twin coil a synchronous rotary spark gap is being assembled, which will allow the tank capacitance to be increased and will provide the maximum possible efficiency.
		Here the power level on the (single) Tesla Coil is slowly stepped up from 0 to 100%, and the sparks can be seen to grow gradually until large ground strikes such as this one are produced.

		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.

	Tesla Coil
		The coil is driven by a lower-high voltage and a spark gap resonator.

		After the primary coil is completed and the frame assembled, slip the secondary coil through the holes in the ends of the frame, centering it so it projects equally from each end of the primary coil.
		If two stiff wires are connected to the secondary terminals of the Tesla coil and bent so they are parallel to each other for a distance of 3 or 4 inches, but separated slightly farther than the spark can jump, the area between them will be filled with innumerable tendrils of violet light.
