Biogas from human waste, safely obtained under controlled circumstances using innovative technologies, is a potential fuel source great enough in theory to generate electricity for up to 138 million households - the number of households in Indonesia, Brazil, and Ethiopia combined.
A report today from UN University's Canadian-based Institute for Water, Environment and Health estimates that biogas potentially available from human waste worldwide would have a value of up to US$ 9.5 billion in natural gas equivalent. And the residue, dried and charred, could produce 2 million tonnes of charcoal-equivalent fuel, curbing the destruction of trees.
Finally, experts say, the large energy value would prove small relative to that of the global health and environmental benefits that would accrue from the safe treatment of human waste in low-resource settings.

Well then make it a health issue and deal with that, but don't feed us BS about what an amazing energy source this would be, because it isn't when it is so widely distributed that the extra 1.9% in usable gas you'd get by collecting it all, would be consumed by the vastly greater amount of energy obviously involved in collecting it. Seriously, who is going to drive 200 miles out into the middle of the rain forest to collect the poo of disparate bands of tribal folk living there and think that is somehow energy conserving?

Then why mention the fact that IF we collected worldwide poo production, we could generate gas for 3 countries? That statistic is stupid because we'd have to spend the gas of 10 countries to get there.
