well am with you on the generator to battery to inverter to appliance front, but shame about the ineffeciency. have got some links on english approaches to the genre- scrap orientated low efficency but very creative! I wanted to see how you've gotten on, whether you tried doing the recumbent thing, and if you thought of trying evenly spaced weights on the spokes instead of a flywheel....My ideal is for a stand you can just drop in any unmodified bike to and get rolling (as in the training roller guy), with an open circuit for 1-4 bikes to combine their power(s). Good luck with it all!
