After watchin scrapheap challenge my son came to me and said that he was going to rip the motor off his mums new washing machine and turn it into a dynamo just like they did on the scrapheap
I did not see the programme but He said they spun a motor by means of a bycicle and produced power enough to light a small bulb
Surely this would not work with a motor designed to run with alternating current
Am I wrong ?
