fair weather current

[Phil]

An interesting subject; makes a great science-fair / school project. It's not difficult to use a MOSFET or MOSFET op-amp to track 1V/cm electric fields, using a small wire grid mounted 1 cm above the ground. You will see some interesting inversions and voltage hikes as storms approach.
