In Britain some scientists were attempting 'pedal powered' electricity for workplaces. And attaching it to exercise for a healthier workforce. If you look what an average man can sustain in terms of output, it is around 150 watts per hour, over an 8 hour day.
So over a 40 hour work week the person could output 6 kilowatt/hours. The average price of electricity in the United States is 10 cents a kilowatt hour. So after a week's worth of output the person could collect 60 cents. Of course the actual wholesale price of electricity is cheaper still, more like 3 cents a kwh.
So the person could wholesale their weeks work for 18 cents.
This also shows how idiotic the idea is that we could return to an animal and human powered world.
