A single-chambered microbial fuel cell protrotype developed by researchers at Pennsylvania State University may have proven that someone's trash could indeed become another person's treasure. During their research, the scientists found that when a steady flow of wastewater was pumped into the chamber to feed the bacteria, bacterial digestion of the wastewater's organic matter unleashed electrons into the electrical circuit and positively charged hydrogen ions into the solution. As a result, the ions reduced the solution's oxygen demand, which is a key goal of wastewater management. Such findings suggest that microbial fuel cell technology may provide a new method to save operating costs of wastewater treatment.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
