The Green Microgym in Portland, Oregon will become the first gym in the country to harness human energy from fitness bikes and convert it to electricity. Specially built motors hooked up to spin bikes will convert energy created by people exercising on the “eco bikes” into 200- 600 watts an hour of electricity, which is then stored in a special battery bank.
