I wrote a story the other day about a University of Kansas project to turn sewage sludge from human waste into fuel.
It's a pretty neat concept that is being tested at several locations around the country. Basically, the sludge is fed into an anaerobic digester that produces gas that can be further refined to power vehicles. The process also helps purify the leftover waste.
If the test works out, we could see such plants popping up all around the country, then around the world. The more we can do to convert our detritus into usable materials, the better job we're doing of completing the circle of life.
It's almost like something Native Americans would have done.
