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.
