Doug,
The lightning rod is the sharpest curve on the building and it is usually
the high point on the building. The excess charge on the building builds
up at the point of greatest ccurvature. The excess charge attracts
oppositely charged ions in the air. This neutralizes the electric charge
on the building. (bleeds off the charge) If the charge does not bleed
off fast enough, and lightning strikes the house. The hope is that it
will strike the rod which is grounded instead of the house where the
lightning will bounce around on the house until it "finds" a ground.
This causes holse and fires. Putting the rod on your neighbor's house
will only serve to protect his or her house nad not yours.
Practice safe electrostatics. Don't put your house out there
without protection!
