Default Horizontal loop antenna

Can you please explain that a little more? If you put 100 watts into a
400 foot circumference loop and it radiates 95 watts, will an 800 foot
loop radiate four times that, or 380 watts? Then can you feed back 100
to put back into the loop, and have 280 left over to run your
refrigerator to keep your beer cold?

Or if the 800 foot loop radiates 95 of your 100 watts, does the 400 foot
loop radiate only 23.75 watts? If that's what happens, where does the
rest of the power go?

Is the radiation pattern the same for a long skinny loop as for a round
one, as long as the enclosed area is the same?
