is it possible to generate electricity by using a bicycle and an automobiles alternator?
i have been pondering this, and have searched the site but found nothing like this, but maybe using a larger inner tube and putting that around a bare rim and a spindle on an alternator to generate electricity? and would the rpms be enough to generate some charge? and also, it would be a\c charge? maybe it would be possible to charge up an automobile battery, if so it would be pretty neat, and useful.
