You failed to consider the conversion efficiency of the people doing
the work... Currently the US Government is looking into harvesting
energy from soldiers as they walk around. They are looking at a
variety of techniques, but all have fairly low conversion
efficiencies. You might have some luck, but I'm not holding my
breath.

Yep, conversion efficiencies all around are likely to be low. Then
again, some folks might be able to put out 200W continuously.

I did the math intending to prove that this was a complete waste of
time, but my results do not conclusively prove that... although, I do
not intend to open a gym of any sort anytime soon.

Just strap TVs to exercycles, and sell them to everyone. It'll
save energy, and help alleviate the obesity epidemic. ;-)

And, of course, if the user turns off the TV and, say, reads a
book while still pedaling, it can feed back to the grid for
credits. That would encourage reading instead of TV. ;-D

Cheers!

High gas prices help too, according to The Independent:
