Saw this great quote in Momentum Planet Magazine. Its from Ivan Illich’s book Energy and Equity.
“Man on a bicycle can go three or four times faster than the pedestrian, but uses five times less energy in the process. He carries one gram of his weight over a kilometer of flat road at an expense of only 0.15 calories. … Equipped with this tool, man outstrips the efficiency of not only all machines but all other animals as well.”
– Ivan Illich, Energy and Equity
