I had found Lidmotor's - Jeanna's light and find it quite amazing.
I would like to replicate this light circuit but would like to modify this and use Tesla's Carborundum button light bulb, using high voltage and high frequency.
BTW, where do I find those large toroid?.
According to his statement, this light will produce 20x for the same expense of Incandescen light. This will be about 5X more effecient than CFL.
I'm new so please help me out.
What will be a suitable coil that will produce the high voltage/ high frequency needed?.
What is the modern version of Carborundum light?. Is there Silicon carbide button light bulb?
He also talks of a hologram light projected off a brass sphere, this will be neat to make and display.
Thanks for your help.
EXPERIMENTS WITH ALTERNATE CURRENTS OF HIGH POTENTIAL AND HIGH FREQUENCY
by Nikola Tesla
Delivered before the Institution of Electrical Engineers, London, February 1892
"Experiments with Alternate Currents of High Potential and High Frequency"
The production of a small electrode capable of withstanding enormous temperatures I regard as of the greatest importance in the manufacture of light. It would enable us to obtain, by means of currents of very high frequencies, certainly 20 times, if not more, the quantity of light which is obtained in the present incandescent lamp by the same expenditure of energy. This estimate may appeal- to many exaggerated, but in reality I think it is far from being so. As this statement might be misunderstood I think it necessary to expose clearly the problem with which in this line of work we are confronted, and the manner in which, in my opinion, a solution will be arrived at.
Any one who begins a study of the problem will be apt to think that what is wanted in a lamp with an electrode is a very high degree of incandescence of the electrode. There he will be mistaken. The high incandescence of the button is a necessary evil, but what is really wanted is the high incandescence of the gas surrounding thee button. In other words, the problem in such a lamp is to bring a mass of gas to the highest possible incandescence. The higher the incandescence, the quicker the mean vibration, the greater is the economy of the light production. But to maintain a mass of gas at a high degree of incandescence in a glass vessel, it will always be necessary to keep the incandescent mass away from the glass; that is, to confine it as much as possible to the central portion of the globe.
Telsla's Hologram
I attach to one of the terminals of the coil a wire w (Fig. 8), bent in a circle of about 30 centimetres in diameter, and to the other terminal I fasten a small brass sphere s, the surface of the wire being preferably equal to the surface of the sphere, and the centre of the latter being in a line at right angles to the plane of the wire circle and passing through its centre. When the discharge is established under proper conditions, a luminous hollow cone is formed, and in the dark one-half of the brass sphere is strongly illuminated, as shown in the cut.
