  • Dielectric properties and absurdities of modern physics
    Dielectric properties and absurdities of modern physics
    Actual orthodox electromagnetism assumes a uniform comportment of
    dielectric inside a capacitor, independent of their aggregation
    (solid, liquid or gas) states. Some simple experiments able to be
    performed in any low level schools demonstrate the contrary. A

    Electrostatics and absurdities of modern physics
    For more then two centuries scientists have been used Coulomb law
    without questioning its validity. Based on well known experimental
    facts the presented text advocate for a limited validity of Coulomb
    law; this is pedagogical fact in order to not scare too many actual

  • Simple Plasma Detector?
    In order to compare 2 techniques for making air-based plasmas, a
    simple and low cost plasma detector is needed. A full Langmuir Probe
    seems overkill. I propose this design and would like the group's
    feedback on its usefulness:
    - 2 rounded wire leads separated by a short distance
    - connect standard household frequency (60Hz in the US) AC to the wire

  • Project idea #2
    Tell a plasma to spin in two directions at once in a tokamak using
    capacitively or inductively coupled plasmas. The objective is to
    increase the kinetic velocity of the atoms in the plasma. The gas is
    so thin, that the potential of a collision is very low. As a result
    the kinetic energy of any ion present could be sent clockwise thorugh

  • Plasma Reactor may not be working for one simple reason.
    The equation as a whole does not ride on temperature alone. I think
    we left out K. The actual operating voltages involved in producing
    the plasmas are still too low. What I mean is that you may require
    something like a tesla coil running at 100 million volts, or need to
    fire single microwave pulses through an solenoid to pull it off. A

  • Is magnetic flux quantified only in superconductors?
    While considering superconductors, it is generally accepted that there
    are created fluxons - some natural number of quantas of magnetic
    flux.

    quantified also in vacuum?
