[grin] Same problem as the 4HP motor, times N: max sustained human power
output is significantly less than 1HP (about 0.1HP, a.k.a. 75W, over an
8 hour period, or in the range of 0.4HP for a few minutes for the
average healthy human.) Add in the power losses, and there's not much
left.

Whoops - my bad assumption (especially egregious since "Femm" should
have clued me in.) Sorry, Kristine!
