Precisely. My understanding is that the Q of the ground varies
depending upon the quality of the connection and the resonate
frequency of the current used to energize it.

More than one coil can be used to receive energy, but the total
energy received is governed by conventional laws of physics. You
can't get more than you pay for. It is also my understanding that
overall efficiency is uneffected by the number of transmitters
and receivers placed on the system.

BTW, I strongly encourage people to duplicate these experiments.
They are not difficult nor expensive to reproduce.

This depends on your input power. I would guess that a 20 - 30
inch OD toroid would be sufficient for starters. When I started
my experiments I was using a 20" diam. toroid, but when my gaps
and coupling caught up to the rest of the system, the coil would 
sometimes let loose with a hot 4' spark from the discharge
