ENTRY DESCRIPTION

Considering the depletion of fossil fuels in our society, there has been rapid development of renewable sources of energy. Populations continue to grow, resources become more scarce. I propose for large MFC devices to create renewable electricity while treating wastewater.

Traditionally, wastewater treatment and waste disposal has been very energy intensive, processing over 50 million gallons every day.  By one account, wastewater contains 9.3 times more energy than how much is spent to treat an equivalent volume. I attempted to take this energy stored with in the organic waste and convert it into electricity through the cellular respiration of microorganisms. Results determined that the most electricity that could be produced was averaged 430 millivolts. To increase this energy production, I want to take the microbial fuel cell onto a larger scale with anode and cathode chambers containing 500 L of matter. Introducing this on such an industrial scale would lead to cleaner water supplies and according to my previously conducted experiment at the wastewater treatment plant, about 100 volts of renewable energy could be produced at a constant current.
