Badass.

I never thought a human could generate useful energy after a science museum exhibit from my childhood made you try to power a 60W filament light bulb with a bike and it was hard to keep it lit.

Or a Youtube video where an olympic bicyclist can barely power a toaster enough to gently singe some toast.

Makes more sense if the human isn’t solely responsible for providing all the energy on demand.

Good point. In hindsight, those exhibits used inefficient 60W filament bulbs. The energy required is all about what you're trying to power.
