Surplus electricity

  1. Hi

    In an off grid system, you may need a system to handle surplus energy.

    One possible solution is an outdoor resistance-heater that "burns off"
    the electricity that is not needed.

    In a national power grid, it is offcource mutch easier to produce
    exactly whats needed, but they may also need similar system.

    This is the solution we have choosen in Norway.

    I'll mail you one end of an extension cord,and you can send it all to me!

    No. If the 'excess electricity' isn't 'burnt off' in resistance heating it just
    makes the PV panel hotter which then radiates the equivalent amount of energy.

    There is however no need to 'burn off' 'excess electricity', any more than 'burn
    off' excess water from a tap.

    Use it to separate out the C in CO2. When you have enough C's, use it
    to power a press to make diamonds for adding sparkle to tinfoil hats.

    AND it scatters the mind control beams!

    :-D

  8. No wonder. They are big fans of Monthy Python.

    If you understand norwegain, you should definately check out more of
    them. Especialy if you speak some danish - this is what norwegians
    think of the (spoken)danish language. After seeing it againg, I assume
    that you dont need to know danish to understand it. (Most of it is
    spoken in english - the way danes speak it...)
     
  9. Hah.

    You do not fool me, with a switch there will be a buildup of
    electricty. Resulting in high pressure and eventualy the wire will
    burst - spilling electrons all over the floor.

    You could offcource have a buccet under the switch in case this
    happens. But it is quite impractical, and you must pour all the
    electrons trough a pretty small opening in the battery.

    As I do not have time to be running around collecting electrons all
    over the house, I "just say NO to switches".

    My experience has been that even the most lonely of the bunch are only
    interested in the larger diamonds - and that even when they get 'em,
    they're still not happy.

    Small diamonds seem to be more generally useful for getting actual
    work (sharpening, grinding, and - of course - beam scattering).

    They come in three technological flavors: [1] manually operated
    mechanical switches, [2] electrically operated mechanical switches,
    and [3] electrically operated non-mechanical switches.

    Generally, I prefer the third type because they also perform the
    important task of protecting the fuses in my circuits - and many
    offer, beside "off" and "on", a range of "sorta" states.
