Bike power (Re: solar power)

Today we were talking about new generation of portable personal 
computers (yes, that is OpenMoko :-) with friends. Our idea was to use 
it as cyclocomputer (That idea has already appeared on the wiki or in 
the list somewhere). We were wondering whether it would be possible to 
charge the phone using a dynamo (
The dynamo uses the energy of the woman/man who rides the bike. It would 
be very useful on long nomad bike tours where we don't have any other 
power source. We did not compare the output of a dynamo to the charging 
current of a cell-phone yet, it is just an idea.

I have another futuristic idea :-). It has no name yet... It is a 
chemical power generator that generates DC using ATP from blood (the 
power source of the muscles). Installing this device in our body would 
equip us with some plugs that could be used directly for powering these 
devices. It is two in one: prevents you from the problem of discharged 
accumulators and also prevents you from getting overweighted :-).

Happy hacking!
