How can you hook up a tredmil to an electric generator to produce free electricity?
It won’t be free unless you are a subsistence farmer, as you’ll need to purchase food to fuel your body to run the treadmill. Basically, disconnect all the fancy-schmancy electronics connected to the drive motor. Figure out the voltage of the motor (probably on a label on the motor). Pretend the motor is a generator. Then buy an appropriate ‘DC to AC inverter’ or ‘AC to AC transformer’ to convert the output of the generator to 120VAC, 60 Hz. Should be good to power a TV or laptop. Don’t connect this to your house wiring, as it could electrocute a linesman if he’s trying to fix the hydro pole down the street, and thinks the power is off. If you really want to live off the grid (or feed back to the grid for profit), you’ll need a special ‘transfer’ switch, and electrical inspection.
