I had a dummy attack. The one I look at is sci.physics. Don Sheade is
still posting his stuff about mass and units of measurement. Arch is into
his Fusion Barrier Law.

Mari Meron still about?
Doubtless wizard baez still slums it occasionally.

I really liked one of Archie's previous ideas. He
wanted agriculture to go to muscle power instead of diesel power. Much more
efficient, you know. Now if we can just get the big city people to pull
farm equipment around manually we'll be set. 150 horsepower tractors are
fairly common in my area. I think a human in good shape can put out about
about 1/3 horsepower. Let's see, 150 divided by 3 equals 450 people equals
900 feet compacting the ground.

'Good shape'! I expect the average continuous output for a city dweller
might be significantly less, probably more like 100W. That puts you up
to 1500 people with 3000 feet. Hmm if each eats 1 kg grains a day then
just feeding them for a year will cost you 600T! Do you think they would
expect clothes and heating as well?

Doesn't seem very efficient to me, but a heck of a good-sized hoeing
gang.
