    Really silly question about lightning

    This is probably one of the silliest questions ever posed- could lightning strikes be somehow stored in a battery of some sort for later use? A REALLY big capacitor?

    Technically yes it's possible. But it's not at all practical. Although lightning has enough energy to kill you, so does the electricity used to boil a cup of water. On another thread some intelligent person referred to it as making a machine that operated using the power of random gunshots.

    doesnt a lightning bold direct itself along the path of least resistance? If so would a capasitor be able to attract a lightning bold when it has the whole Earth's surface to use as a capasitor?

    The voltage drop in the vertical is tremendous, something like a couple hundred volts from your head to your toes, but there is very little current. That leakage can be taken up in a large metal object that's insulated from the ground--if it has sat for a while and built up charge, touching it will kill you.

    Nah...that was definitely...

    "...But, is it impossible?"

    In fact, lightning is due to the breakdown of the dielectric in a natural capacitor. Here's a nice little page on it:
