The marathon runners generated 4.7 kilowatt-hours of energy
That’s a little more than fifty cents’ worth of electricity
I’ve already commented on this system, but I’ll sum up:
– It’s converting roughly a dollar’s worth of food into a penny’s worth of electricity. If they weren’t stealing the energy from people, this would never save anyone any money.
– The energy they steal is not green, so this energy is not, despite the effort to “launder” it.
– It’s still not clear how long it would take to save enough to pay for such a system
