has a 16kWh battery. According to an article about a pedal-powered
supercomputer , 10 bicyclists could power a 1.2kW computer for 20min.
So as a lone bicyclist, you might be able to provide a power of 120 Watts
(but but not for many hours on stretch). 16kWh/0.12kW makes 133 hours.
I think I'd have cycled where I wanted to go before managing to recharge
On the hand, with slight advances on computer power usage (that are
already there in laptops), you might be able to power your desktop
computer by cycling simultaneously...

hybrid expected out in 2010 and will apparently drive 40 miles on a charge
without using any gasoline. The pedal-powered generators that I'm referring

CFP: I am guessing that the pedal power needed is much more than the
actual pedaling on a heavy bike to ride the 40 miles... but that
comparison would be interesting: how much more pedaling (energy
expenditure) is needed to power an electric car.... but I can't help in
