Years ago, we were approached by one of the Port-O-Let dealers in Michigan. He had this idea he wanted us to help him develop.

Energy from sewage- revisited
We reported yesterday about Dr. Bretschger’s (J. Craig Venter Institute) MFC (microbial fuel cells) to recover energy from wastewater. Today, we’ll discuss a slightly different version, under development at Penn State University and for which results were recently published in Science.
Sewage as an energy source?
One of my theses involved the conversion of Honest-to-Goodness Solid Waste (HGSW) to energy. The process made sense then- and makes even more sense now. (Believe it or not, there’s only one company examining this process on a large scale, some 4 decades later.) But, we also need to treat our liquid wastes (sewage)- because we want to keep our rivers and streams (which is where we discharged those treated waters) safe. Amazingly, we employ about 2% of our energy supply to treat this waste stream.
