1) How much does charcoal use contribute to indoor air pollution? And how large are the negative effects in expectation?
2) How much active time/labor/attention does typical Ugandan bean cooking take? If it takes ~2.5h to cook beans and soaking them reduces it by ~30%, the time savings would be ~45minutes/day or 273 hours. If you conservatively value cooking time at $.10/h, this is worth $27/year, which is considerable. But this assumes active maintenance, which might not be a realistic model.
3) How large are typical households/ how many people cook for a household? If households are ~5 people, and only one person cooks beans for the entire household, then the time (and possibly indoor air pollution) savings are amortized by a factor of 5.
But this is all very first-principles-y, I’m sure people on the ground would have a much better sense!
Interesting! 3 potential cruxes for me:
