    seen something like this elsewhere, the only thing that worries me is
    woods lack of earthing ablility.

    Wood will conduct lightning!, what are you
    worried about!!.
     
  5. Actually, wood doesn't.

    Tell that to the 3 or 4 people who got fried under an old wooden
    bandstand in Geelong some years ago...

    Put enough volts across it and it certainly will.
     
  8. Its not the wood thats doing the conducting.

    Yes it is.

    Oh, I'm sorry, it must be the carbon ions forming
    a conductive plasma as the cellulose is explosively
    vapourised.Either you know something about dielectric
    physics you aren't telling us or you are being a
    nitpicking dickhead.

    So pray tell what it is that does the conducting?

    And don't say electrons, because by that logic metals wouldn't be
    considered conductors.

    Me thinks you should go back to physics and chem 101. Or maybe better,
    go back and start in say... year 10 or 11.

    There aren't too many laptop cases with any earthing ability anyway. I don't
    think that the plastic case on my Dell would conduct too much.

    Anyway, if you're that worried, you could just hammer a nail or two into it.

    You'll find it was the water that was the conductor, not simply the wood.

    Wrong with dry wood.

    Dry wood is an insulator - not a conductor. For the purpose of earthing -
    which is where this started, wood has NO conducive conductive abilities.

    Depends entirely on the level of voltage
    applied, just like with any insulator.
    Irrelevant to where it diverged to.
    Pity about the situation that it diverged to.

    om.au...

    Lets see , Carbon is used in low voltage batteries , wow with only 1.5 volts
    present . TTL is 5 volts .
    Man , now Im worried !!!

    And you should be. Carbon is used in some cells. With carbon/zinc or
    alkaline you get the 1.5 V you sprout about.

    A battery is a number of cells connected in series and / or parallel

    How you manage to get from the voltage of a lightning strike to a
    carbon/zinc cell is quite a step.

    ps still think a file is created when cloning a disk ???

    Well in the context of grounding a laptop, wood is useless and would act as
    an insulator. In the context of the 'bandstand' incident, water was the
    conductor - NOT wood.

    In both instatnces wood was/is not a conductor.
    Somehow we diverged to the Geelong incident. The lightning was conducted by
    water from the thunderstorm - not the wood.
    Which was the situation where water was the main conductive substance - NOT
    the wood.
    You said wood was doing the conducting - it wasn't.

    Its an option
