Nanotech coatings offer possibility of ‘brown’ electricity from sewage

Nanotech coatings offer possibility of ‘brown’ electricity from sewage: "While much of the focus on renewable electricity production focuses on green alternatives, a team of engineers at Oregon State University is looking at ways to improve electricity production from a “brown” source – namely sewage. The engineers found that using new coatings on the anodes of microbial electrochemical cells they were able to increase the electricity production from sewage about 20 times."
