Explosive ejection of higher frequencies by lower freq In 2 tesla coils

AI Thread Summary
The discussion centers on the phenomenon of ball lightning and a proposed method for its generation using two Tesla coils with different resonant frequencies. The lower frequency coil induces a current in the higher frequency coil, leading to constructive interference that supposedly releases energy and forms ball lightning. However, one participant argues that this method will not produce true ball lightning, as it may only create small hot plasma balls, which differ from the natural phenomenon. Additionally, anecdotal evidence and personal theories about ball lightning are shared, emphasizing the complexity and mystery surrounding its occurrence. The conversation highlights the challenges in replicating historical accounts of ball lightning, such as those attributed to Nikola Tesla.

Greetings PF'rs
I'm researching a phenominon called ball lightning and one supposed method of generating ball lightning is to take two tesla coils of different resonant frequencies but are pulsed with the same secondary coil. The lower frequency coil induces a current in the nearby higher frequency coil and when the two waves in the HF coil constructively interfere, all the power in the HF coil is released at the location of the peak interference and the charge collects on a piece of soot on the wire, forming ball lightning.

I spoke to my friend who works on the power grid about this phenomenon and said he had heard of it before, although not in this context and couldn't remember what the effect was called. Can anyone tell me what this explosive ejection of charge is called?

Tay, Sorry, but I cannot offer you any information on the explosive ejection of charge. I was able to find the same experiment, however. In the “Operation” section under experiment #1. these authors mention Tesla’s “Low Q” explanation and admit it is correct, but they explain the process by the rapid changes in coil impedances.

However the experiment works, my comment is that the above experiment will not produce Ball Lightning (BL) as found in nature. It may produce small hot plasma balls, quite interesting in themselves. But BL is not hot plasma. If it were, it would rise in the air and it never reported as rising. Also, it forms in nature without high frequency oscillators or carbon soot.

I have extensive anecdotal reports of BL observations worldwide, a large collection of technical material, and even my own theory of what BL consists of. If you are interested in persuing any of this, send me a private message.

Cheers,

I recall reading In a bio about Tesla that one of his party tricks was to reach into his briefcase and retrieve glowing ball lightning which he would juggle for a while before returning it to the briefcase. No one has ever been able to replicate this, or even suggest how he could have done this.

Maybe you'll be the one to rediscover it ... http://imageshack.us/a/img502/7752/goodluckemoticon.gif

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
