|Like most Americans I eat too much and do not get enough exercise. I also watch TV too much.|
I modified an exercise bike to produce electricity. The electricity runs a tv, radio, lights, fans, to use the power that I am generating. Old car alternator, with a a small battery to get the field excited to start the generating. 250 Watts is a lot of work.
For a light workout pump during the show, and rest during the commercials, For a full workout watch a DVD movie and pump the whole time.
