Prisoners' feces is converted into combustible "biogas," or methane gas that can be used for cooking. It has reduced by 60 percent the annual wood-fuel costs which would otherwise reach near $1 million
Perhaps the positive effect of the Glorietta gas explosion is the renewed awareness of the feasibility and power of biogas. I mean it has demonstrated that every building that has a septic tank underneath is veritably sitting on an oil well. Now if a greated effort is exterted in the collection of human waste in sewers to process and extract methane from it, perhaps we can actually blow away our dependence on Middle Eastern oil. Hopefully.
