David HoA person on a bicycle is by far the most energy-efficient among animals and machines per distance traveled relative to body weight. The bicycle is magic.
iamBullivant@davidho A helicopter or a jet fighter is more 'efficient' that a fruit fly or a bee? Really?

Energy per gram per km.
A jet is polluting, yes, but energy per gram per km it's not bad. Change that to energy per passenger per km and it'd be a different result.
