I need all the info I can get about how to generate electricity with pedal power. I am going to read this thread, (must take it home on paper, no Internet in my house. I pedal to the library)

what I have is a generator, I think it is DC, but want to know are there more efficient devices? I presume that an alternator would just wast power being converted to DC for the batteries.
And that lead acid should be charged slower than Lithium. Not that I can build a fast charger... And I saw a video about how they went directly to the generator from the crank making a relatively slow charge.
But I am worried about the load of charging and getting the thing spinning fast enough. May need a heavy flywheel to keep a regular RPM.
And how efficient can one be? what a re the power losses.
I will be back with more intelligible questions on Monday.
This wil be just to charge two small 8 amp hour batterys.
