When work is really work

OK- so I have this idea for a new workplace. People like to work out- can't find time because their jobs get in the way, yadda yadda. We eat too much and need the exercise to keep our bodies in the idolatrous shapes we like them to be. So, how about if your job was to work out? I mean, you went in and for say, 2 hours in the morning and 2 in the afternoon, with a good break in the middle for rehydrating, you simply walked/ran on a treadmill or lifted weights or some other machine assisted exercise. Why machine assisted? Well, because what you would be doing is using your motion to generate electricity! Just like there are special batteries connected to solar panels that store the energy so it can be used later, so too would these machines be attached to special batteries- so as you ran, you would turn a crank that turned a small generator that stored energy in batteries for use other places! We could use the power for an associated business, say like my local foods grocery store, or a great bookstore/toy store/coffee bar. Or perhaps powering a recycling plant. And if we generated too much power, we'd just sell the excess back to the grid! What a win-win. I mean, the requirements for the job are very low- can you walk? How about can you lift weights? (even most folks confined to a wheelchair can do so). You would end up in great shape, you'd get paid a basic wage, and we'd have a renewable sustainable energy source to sell to people everywhere. As for pollution, I suppose we'd end up with some sweat issues- but I don't see that being a project ender. So, what do you do for a living? I work. Work out that is.
