Comment on This is a real machine in Romania. Do 20 squats in front of it, and it prints you a free bus ticket.

  1. Why are we talking about squats?

  2. Why are you talking in terms of watt hours and why is 2min somehow equivalent to 3?

    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 cheaper much computer too.
