:)starting a new project at school making a generator from a washing machine and a push bike //http://www.watchtv.net/~rburmeister/smart%20wiring.html (http://www.watchtv.net/~rburmeister/smart%20wiring.html)

So are you going to set it up to power a lathe that you can use while pedalling?

not sure how many AMPs it will pump out:? run on 12v with a inverter

the other side of the project is makeing the bike to run the generator this will also be used to power the a boat that we race at the end of the year so with some gears l could run a lathe

and I suppose a future project will be a boat that spin dries clothes :cool:

The only problem using human power is a very fit person can only generate about 200w of power.

You'd be better off direct drive, running a gen and inverter plus a motor will introduce a fair percentage of inefficiency. Maybe you could over come this with some solar cells to boost the output?

the stationary bike is made so we can run different things of it

Might be worthwhile having a flywheel to even out the fluctuations.

where would you put the flywheel in the gearing at the start (slower) or at the end

Not sure. You'd probably get away with a lighter one if it was spinning faster.

I hear that the Aussie cricket team could use a little more training, hello 2400w.:D
