         I know of one gentleman whose Wife in order to get him to exercise 
planted the stationary exercise bike in the den with a GM 35 amp alternator 
attached by one v-belt with a deep cycle battery for the alternator to 
charge. Mounted on the handlebars is a 7 inch color TV 12 vdc powered.7 mph 
generates around 15 amps according to him and he has lost 38 pounds since 
September. He finally got over the loss of the 27 inch console as he 
started to lose weight. He says it's much easier to drive the M-38 without 
the gut touching the steering wheel.
