You also need a big enough battery to get through slow hours.

So you can get the Zero-emissions Off-the-grid gym!

    It would have to be a pretty big relay team. The recovery time for 2 minutes of all-out power exercise is pretty long.

    Look at the size of this guy’s thighs. He’s a freak of nature (in the positive sense of the term) who trains for this specific type of exercise and had to stop after 2 minutes because he was in so much pain. I can’t imagine he’d be ready for another all-out run in less than a couple hours, and after two in a day, probably would need a day’s rest.

      6 guys simultaneously doing 100w for an hour has a much larger “relay pool” of available athleticism.

        That’s fair. But that’s still a lot of work for so little work, if that makes sense. Which is kind of what the demonstration showed.

        A man at the peak of human athletic capability could barely put in enough energy on his own to slightly toast a piece of bread. Of course 6 people could put in one sixth of the effort, but that’s six people still working such a small output.

          For a 2 slice toaster, they could make 60 toast per hour. Primitive human hunters had an endurance advantage over all prey, as sweat is a cooling system. They could run long enough to exhaust the prey. I still imagine horses could produce more electricity. Though apparently a horse can travel just 20-30 miles per day, while an average cyclist could do 60+.

            That’s 1440 slices of toast per day. Using random numbers from google, that’s 110k Calories worth of plain white bread. Assuming 6 people putting in the work, that’s a bit over 18k per cyclist for 24 hours cycled, who each would require about 12k Calories for the work put in.

            However, this is just to toast the bread, not to make the bread. I’m being a little dumb and taking this hypothetical a bit too far.
