I'm making bike rollers, and I was wondering if I could hook up a dc motor as a generator to one of the rollers and connect the positive and negative of the motor with a watt meter in between. Would this tell me the watt output of my body? ( motor efficiency and friction would lower these numbers of course) Or would I need some sort of load on the generator to make it work? via /r/DIY https://ift.tt/2Mcj7bc
