Re: Charge on the Earth

John,

	You are correct, I miscalculated the capacitance.  However, most
practical capacitors (which occupy about the same space) have capacitances
that are much larger typically hundreds of pF, so I still think my
argument is basically correct.  The excess charge would typically be less
than 0.01%.
