What current do you measure in a wire connected to your 12v car battery, and hanging freely into the air? This is the current caused by your electrons flowing into the air. |

Adequate to electron emission. Transmitters do not emit electrons. "Negative corona take place at each voltage: "A corona is a process by which a current, perhaps sustained, develops between two high-potential electrodes in a neutral fluid, usually air, by ionising that fluid so as to create a plasma around one electrode, and by using the ions generated in plasma-processes as the charge carriers to the other electrode. Corona discharge usually involves two asymmetric electrodes, one highly curved (such as the tip of a needle, or a narrow wire) and one of low curvature (such as a plate, or the ground). The high curvature ensures a high potential gradient around one electrode, for the generation of a plasma. Coronas may be positive, or negative. This is determined by the polarity of the voltage on the highly-curved electrode. If the curved electrode is positive with respect to the flat electrode we say we have a positive corona, if negative we say we have a negative corona. The physics of positive and negative coronas are strikingly different. This asymmetry is a result of the great difference in mass between electrons and positively charged ions, and so only the electron having the ability to undergo a significant degree of ionising inelastic collision at common temperatures and pressures. An important reason for considering coronas is the production of ozone around conductors undergoing corona processes. A negative corona generates much more ozone than the corresponding positive corona. " From: http://www.wordiq.com/definition/Corona_discharge "the tip of a needle, or a narrow wire" is a source of the "cathode rays". They were identyfied in 1895." They emit electromagnetic waves. You only see electric current in the feed to the antenna, not externally. And what about the "displacement current? When the antenna is not driven relative to earth, this is not causing current into the earth, and so no connection to earth is required. Probably it is the coax: "Many conventional coaxial cables use braided copper wire forming the shield". The transmitted signal flows only along the inside of the shield of the coax.

But in my cellphone, the coax feeding the antenna is maybe only 1cm long, or even shorter. How can you call it a "large conductor"? "Large enough." I also belive in each Tesla's word.

You are again attempting to make something that sometimes exists into something that allways exists. No chassis. No ground, as in to the Earth, connection. The "large conductor" works as the earth. On many modern circuit boards there is no large conductor. You are a babbling idiot. |

S* So you agree that a transmitter needs no connection to the earth? Of course YES. The "large conductor" is enough. There is no "large conductor" on many modern circuit boards so you are wrong yet again. |

Because, you babbling idiot, in many cases the "large conductor" you are obbsessing over doesn't exist. Probably it is the coax: "Many conventional coaxial cables use braided copper wire forming the shield". Wrong again; most portable radios have no need for any coax, I also belive in each Tesla's word. He discovered that in his secondary coil is the oscillatory electron flow from the earth into the air. This is gibberish. Why is it impossible? What is what impossible? The only thing I see that is impossible is for you to understand anything. |

He discovered that in his secondary coil is the oscillatory electron flow from the earth into the air. Why is it impossible? Because RF EM waves are not made up of electrons. The particles that are flowing in an RF EM wave are photons. RF waves travel at the speed of light. Electrons cannot travel at the speed of light. Electron waves travel. Electrons have different speeds like the all gases. There are no "Electron waves". Comparing free electrons to gases is idiotic. If Tesla actually believed that an RF wave consists of electron flow, he was simply ignorant of quantum electrodynamics. That may be the reason why he failed to transfer large amounts of power through the air in an efficient manner. He wrote that for this you must use the higher frequency than was possible in his time. Nonsense. Now all transfer large amounts of power through the air in an efficient manner. More nonsense. Light is an example. But now we have the free electron laser. Yet more nonsense. You are a babbling idiot. |

Anyone understand what Szczepan means by "oscillatory electron flow", please? I'm assuming he means a sine wave or a push-pull current. Regards, Ian. |
