The use of human poop as fuel for public transport vehicles

Did you know that in one year, the human waste that generated per person for 1 year can produce 2.1 gallons (8 liters) of fuel, in this case methane gas? Maybe that number is not too large even arguably very small to meet the fuel needs of your car alone, but what if all of it collected in one city?
The Bristol bio-bus is fuelled using gas from sewage and food waste from a local waste treatment plant GENeco. (Picture from: http://bit.ly/1p4qTm5)
With this assumption, then the city government of Oslo, Norway in 2009 decided to use the buses with fuel from human faeces. With a population of Oslo as many as 250,000 people were then multiplied with 2.1 gallons of fuel, the results are all that can meet the needs of 80 buses with the distance of each bus as far as 100 km.
Toilet humor aside, biomethane gas is a legitimate source of renewable energy. Governments should not constipate the efforts to introduce new forms of energy into public transit systems. There really should be poop buses on every street. (Picture from: http://theatln.tc/14Uvqib)
This is also done in the UK by GENeco, a subsidiary of Wessex Water. Reportedly they made a bus with a capacity of 40 passengers and uses the human faeces and food scraps that have been converted into bio-gas as its fuel. With once refueling, the bus was able to run up to 300 km and is currently operated and used by Bath Bus Company as public transport to the Bristol airport.

GENeco is the first company in the UK that manage human sewage and food waste into energy sources (bio-gas) and be a company that supplies fuel to those buses. And according to them, the human waste and food scraps can produce enough gas to lights up 8,500 houses in the UK.
Therefore, it can be calculated how much the fuel savings that can be done in one year and also the environmental pollution problems can be reduced. Indeed, it was a bit of "disgust" if we thought of how the buses can run. :-) *** [EKA | FROM VARIOUS SOURCES | THE ATLANTIC]
