So that would give a current of about 0.06 picoamperes per square foot?



I assume that's an average value. Localized values could
be much less or much greater.



It is the 340 amperes divided by the surface area of the earth in square
feet. I guess you could call it an average.

So, "much greater" than 6E-14 would be what, maybe 6E-13?
