Gosh.  That's truly amazing.  All I need to do is lay down on the
ground, which drops my center of mass to ground level, and I get a
free increase in "power".

Don't even pedal! Just stand up while doing a track stand at a red
light. The instant the light turns green, sit down. Your bike will zoom
off the line even without pedaling!

Instead of up and down, rock the bicycle +/- 45 degrees to the left
and right.  By Tom's amazing physics, one should gain "a rather hefty
320 watts" to power the bicycle hopefully in the forward direction.

Far off topic drivel:
I went to the local smog station yesterday for a smog check.  We had a
small problem moving my Subaru from the parking lot to the service
bay.  The smog technician didn't know how to drive a stick shift.  By
coincidence, neither did anyone else who was available.  We had to
wait a few minutes until someone could be found.  I wasn't allowed to
drive into the service area because I wasn't covered by their
insurance policy.  It's problems like this that make me feel really
old and make me wonder if 20 years from now, bike shops will have
people available who know how to ride a bicycle without electric
assist.
