How about the capacitors and antennas on Voyager I and II which are still operating at the edge of the solar system? -- 73, Cecil, w5dxp.com You see the Voyager I and II use their metal structure as one plate of a capacitor connecting to earth. The space between is the dielectric, The dielectric is in the textbooks. In real space is the rare plazma (conductor). " Since plasmas contain equal numbers of electrons and ions, they are electrically neutral overall and thus electric fields play a lesser dynamical role. Because plasmas are highly conductive, any charge imbalances are readily neutralised." "Norwegian explorer and physicist Kristian Birkeland may have been the first to predict that space is filled with plasma. He wrote in 1913: "It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. We have assumed that each stellar system in evolutions throws off electric corpuscles into space. It does not seem unreasonable therefore to think that the greater part of the material masses in the universe is found, not in the solar systems or nebulae, but in "empty" space."[1][" From: http://en.wikipedia.org/wiki/Astrophysical_plasma S* |

Just as a mental exercise, assume that the entire setup...van and antenna, is transported to a place in space where there is negligible capacitance to the earth. Is it your contention that the setup would operate any differently? # The Earth is in the space and the entire setup also. # The both need "neutralization" like the space-vehicle: # "Other proposed applications of large-area field emission sources[39] # include microwave generation, space-vehicle neutralization" # From: http://en.wikipedia.org/wiki/Field_electron_emission # # " Where the electrons are compacted the electrons tend to push each other # off. Where there # is a deficit of electrons, electrons are attracted from other sources". # # In space is the Solar wind (ions and electrons). # S* And if the van/antenna had been constructed on another planet before being sent into space, is the earth still required or just the other planet? # Each piece in the space is neutralized by the rare plazma. # S* Thanks. Your answer confirms many of my suspicions. |

Everything floated above ground without incident and many QSOs.) I value your opiniion. In Marconi opinion: http://www.nobelprize.org/nobel_priz...ni-lecture.pdf "By "connected to earth" I do not necessarily mean an ordinary metallic connection as used for ordinary wire telegraphs. The earth wire may have a condenser in series with it, or it may be connected to what is really equivalent, a capacity area placed close to the surface of the ground (Fig. 4). It is now perfectly well known that a condenser, if large enough, does not prevent the passage of high frequency oscillations, and therefore in these cases the earth is for all practical purposes connected to the antennae." And Wiki: "The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles such as ships, aircraft, and spacecraft may be spoken of as having a "ground" connection without any actual connection to the Earth. This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) which serves as the common return path for current from many different components in the circuit."

I am going to love this answer. tom K0TAR |

That's "between the plates" and not "flow to earth". The Earth surface works as the plate. And so it will have delay related to the transmitted frequency. So that part will be predictable. But you won't have a clue as to how it works, as usual. tom K0TAR |

Hi Do you have any links about the relative potential of planets ? I have always been wondering what would my meter indicate if connected between an earth and a moon terminals. On the other hand electrons move quite easily in vacum this was used in radio not so long ago. But of course much slowly than electromagnetic waves. --- Posted via news://freenews.netfront.net/ - Complaints to --- |

Light (and radio waves) are the oscillatory flow of electrons (L. Lorenz 1869). Glass, ice and water are insulators. As you probably know the wires insulated with the water do not work. It is the wave lenght dependent. S* |
