Interesting question. One horsepower equals approx 745 watts and I have
seen test rigs (for endurance testing) where a human riding a bicycle-type
generator/alternator (don't remember which) was able to run a small
television set. I would estimate that output to be around 100 to 150 watts
- or around 1/6 horsepower. The subject was only able to maintain
television reception for a relatively short period of time before becoming
too fatigued (a matter of only a few minutes). Don't remember what my
R390A draws, but believe it is more than 150 watts - too lazy to disconnect
and remove from rack :-)) I believe the R390 draws more current than a R390A.
Another problem would be the varying voltage depending upon the speed of
the bicycle rider which would require a voltage regulation system.
Sounds like it might be an interesting experiment.
