    We’re comparing no power generated to any power generated, ignoring the equipment cost thats infinite gain.

    You have to subtract the cost for the power generation station from that, then it’s negative profit margin.

      You’re already building an exercise station whether it generates or not, you have to compare the two. Bike station doesn’t need cameras and sensors, probably much cheaper computer too. Heck, the power savings from dropping the detection equipment and algorithm are probably more than the power generated.
