Shorting coil gives back more power

Maybe this will shock the reader:

He is using a mechanical and magnetic flux jacking in a ringing or singing mode. Look at the field / sine / dc explanation.
This is a Johnson Rotovertor with the Generator and Motor meshed on the same plane and central axis. The rotational mercury core is similar.
Searl is also a Scottish rite Mason.

   When you short the coil, the field colapses down, thus a change in the mag field. Soon as you release the short, the mag pulls the field back up again. Try it on the bench for yourself.

use paint or such and always draw a schematic.
You will get more of an answer.

shorting means making a or creating continuity in a circuit,

Some use that term in that context.  Continuity in reality is a closed loop. When a meter is used for continuity,then the power source is turned off and the meters battery voltage is used. If the meter is set on continuity and the power source is on you will burn the meter up.
Electricians never use the term short for continuity. A short would be a bypass of the current to a metal box,a device,or another wire which would go to ground or the device.  Plugging in a lamp or other device you can sometimes see sparks. The original closed loop current is directed into the lamp. The lamp settles in to the original closed loop becoming part of that loop. The coil in question here has both ends of the coil wires tied together in its own loop. Power is then applied to the wires intermittently. If the current continued it would burn up the coil.
