If you stopped to think about what you are saying you'd realize how
ridiculus it sounds. If a bolt of lightning (MEGA volts at MEGA amps) struck
the lightning rod sitting on a wooden barn or house, you would really be
talking FLAMES. Even if the wire cable that would be carring the current to
ground was low resistance, at that current there would be a LARGE voltage drop
across the cable. The power disapated would heat the cable red hot; not
exactly something you want attached to your wooden structure.
