I wonder how this ranking might change if we also took into account the energy required to produce the extra calories that humans need to consume in order to get around via these modes of transportation.
Like, you'd probably expend a lot of calories traveling 10 miles by unicycle, and over time maybe that would be more significant than the materials difference compared to cycling?
Of course, it depends a lot on the diet of the human in question.
