Is It Possible: Invisible Wire

  1. Aug 7, 2010 #1
    Is it possible to make an invisible wire? Heres how It would work. You would have an electron gun shooting electrons and then you would have a wire carrying x amout of volts. Then you would put the wire into the electron flow. The electrons would then act as a wire and "transmit" the x amout of volts over a sertain distance. Would it work?

    In a vacuum? Like a TV picture tube? If anyone remembers those...

    According to Lem many years ago there was a brilliant inventor who learned how to draw very thin wires. One day he draw wire so thin, that it didn't exist. That's how wireless telegraphy was invented.

    When electrons fly through air, it's usually quite visible.

    You might want to start with figuring out the mean free path of electrons in air. After you discover that, then you may want to rethink your original question again.
