Matt: electrons are easly emmited from a point. Electrons do not tend to
emit from a large smooth surface. The electron density on a point repells
space electrons away from the point toward the cup so natural current flow
is from the point toward the large area cup. Much the way a FRANKLIN
lightning rod works to discharge your house roof durring a storm.  Point cup
current flow is still used inside special photo  vacuum tubes today.
