An interesting 6 and a half minute clip on two villages in Guizhou and their fuel feed stocks.
In the first village (Bird), you have the old way of gathering fire wood and using coal to provide the fuel source for warmth and cooling. While in the other, you have the biogas separator which takes input from human and animal sources and puts out fertilizer and methane fuel. Fuel that can support a family for their daily needs.
One simple solution (requires about 800USD of investment) that addresses core problems of deforestation, air pollution, ground water pollution, sanitation, and energy.
Lot’s of positive footprints in the right direction.
