Easily? During the Tour de France, a commentator remarked that Lance
Armstrong could produce 400 watts. He didn't say for how long, but it
left me with the impression that 400 was very impressive. Keep in mind
I don't even own a bicycle.
As a side note; Armstrong made me proud to be an American. Not just
for his cycling skill but his self control. The first time one of
those oh-so-civil Frenchies spit on me, I would have had to stop and
punch some manners into him.
I heard 600. There's some variation in what the right figure is, and
what normal bike rider is, but it's up high enough to move volumes
of water comparable to a sump pump.
The trick is pacing, incidentally; running always _just_ below what would
wear you out, rather than randomly above and way below, which is what
a novice does, and burns himself out on. Which is where regular
practice comes in more than muscle.
To put things in perspective Egyptian farmers still use the hand
cranked Archimedian screw to raise water for irrigation. Its made of
wood and is not an efficient machine. I haven't any idea how long the
farmer keeps at it. Hand cranking must be pretty tiresome. But the
method has been around for more than 2000 years and it gets the job
I think the spitter was a German fan of Ulrich something and the
whole idea was to upset Lance and screw up his concentration and
replying to Ron Hardin, power out wrote:
Good question. The OP showed enormous patience if not excessive meekness in the
face of so many ignorant disrespectful replies, by people who mostly don't know
or care anything about the problem or possible solutions.
And you sir, are to be commended for waiting 13 years to comment. Most
people count to ten but you seem to have waited a bit longer to
ventilate and share your caring and sensitive feelings. Thank you for that.
I do have sad news though. The original poster lost his life in a
storm. One night the power went out and the basement started to flood
so he hopped on the bicycle and started pumping. he did well until
darkness came and it was time to feed the gerbils. He got off the bike,
fed the gerbils and on the way back to the bike, slipped in the water
and drowned. Thirty gerbils tried to rescue him but they too drowned as
they got cramps from going in the water after eating.
A bicyle powered water pump (which could easly
be used as a sump pump) was a key plot
device in the novel "The Ugly American".
NOTE: while that term has become synonymous
with the US braggard who runs around the
"third world" bossing people and being
an asshole, in the actual book the "Ugly
American" was a good guy.
