I’m curious what moped km per day one could generate with human waste, food and yard scraps.
Here's my rough estimation: Anaerobic digestion of food and green waste yields ~0.22 toe/tonne of biogas, and manure yields up to 0.04 toe/tonne [1]. (toe = tonnes of oil equivalent) Australia wastes 300 kg/year/capita of food [2] (across the entire supply chain, from farm through fork) Americans generate 90 kg/year/capita of yard waste [3] That's 1.07 kg/day, for 0.24 kg of oil equiv. The average adult produces ~0.4…
This is actually pretty amazing.
One could commute to and from work and it would be arguably greener than solar or wind.
