Is the "Load" Really the Source?

    I was talking to an inventor who claims conventional electronics is
    explained "backwards".

    The power for a circuit actually flows from the load to the so-called
    supply, and amplifiers get hot simply because they resist this.

    I assume he is referring to some higher energy potential in the
    atmosphere that only needs the proper conduit to be tapped into.

    The battery or power supply functions as the point of attraction or

    An analogy would be that we are trying to pump energy up when we
    should be providing an unobstructed path for it to descend to a lower
    rest state.

    Is there any chance this could be possible?

  2. He must be a Democrat ;)

    Conventional current flow is opposite the flow of electrons. If that
    means anything.

    "Bob Miller = Gullible Jerk "

    ** Can he explain why is it that batteries go flat ?

    Lemme guess, he invents perpetual motion machines - right ?

    Does he sell dark-absorbing bulbs also?

  5. Guest

    Did he explain that last Sunday ?
  6. Absolutely not. Light bulbs 'give off light', they do not 'suck dark'.

    More likely he takes money off investors for a "free energy" scam.

    Our convention that power comes out of the supply and ends up either as
    heat or in the load arises from a mathematical model of the way part of
    the universe works.

    If he can construct a model that contains a quantity that the
    mathematics reasonably describes as flowing from the load to the supply,
    and in some way accounts for what we conventionally regard as heat
    dissipation due to inefficiencies, then his model may be as valid as the
    one we use. It would be somewhat confusing to call that quantity "power"
    since that term has already been used to refer to the quantity in our
    usual model.

    But it's a big "if". Most likely he's just waving his hands in the air
    after partaking of some illicit substances.

  9. perhaps he's living near a TV broadcast station?
    What is 'reversed' is _probably_ the usual conventions used to describe
    power transfer in electrical circuits. Loads are thus producing a
    positive Wattage and sources a negative one. This makes totally sense
    when observed from the 'outside', say a heater giving off(+) energy. Or
    a battery depleting(-) it's chemical reservoir. From the 'inside the
    circuit' perspective it looks reversed of course. The thing that matters
    for the direction of energy transfer is that the signs are _different_,
    not what they are...

    And of course there's also the difference between direction of current
    and electron flow as someone mentioned here earlier. This is due to
    historic reasons and does not make a difference either, as long as it is
    used in a consistent manner(=do not switch conventions halfway through

    but he claims the cash is flowing from him to the investor...

    What? a new physics?

  12. Does he know what "entropy" means? Perhaps he could benefit from a bit
    of Carnot knowledge of thermodynamics.
    Well, some power _will_ flow from a load back to the amplifier if the
    amplifier is not powered but a conductive path exists and the load is
    slightly warmer than the amplifier. Someone could probably work this
    effect into a potentially convincing Powerpoint presentation.

    As in: "That Carnot possibly work"?
