Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity. The new technology developed at OSU can now produce 10 to 50 more times the electricity, per volume, than most other approaches using microbial fuel cells, and 100 times more electricity than some....

Some of the planet´s tiniest inhabitants may help address two of society´s biggest environmental challenges:  how to deal with the vast quantities of organic waste produced and where to find clean, renewable energy. According to César Torres and Sudeep Popat, researchers at Arizona State University´s Biodesign Institute, certain kinds of bacteria are adept at converting waste into useful energy.  These microorganisms are presently being applied to the...

A new biofuel production process created by Michigan State University researchers produces energy more than 20 times higher than existing methods. The results, published in the current issue of Environmental Science and Technology, showcase a novel way to use microbes to produce biofuel and hydrogen, all while consuming agricultural wastes. Gemma Reguera, MSU microbiologist, has developed bioelectrochemical systems known as microbial electrolysis cells, or MECs, using bacteria to...

New catalyst dramatically cheaper without sacrificing performance Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may lead to much more affordable energy conversion and storage devices. The material —...

CU Denver team develops process resulting in 70 times more energy A team of scientists from University of Colorado Denver has developed a novel energy system that increases the amount of energy harvested from microbial fuel cells (MFCs) by more than 70 times. The new approach also greatly improves energy efficiency. MFCs are emerging as a way to use bacteria to directly harvest electricity from biodegradable materials, such as wastewater or marine sediments The energy from a single MFC...

Researchers from Penn State University claim that they have developed a prototype device that can use wastewater to create electricity, essentially transforming treatment stations into power plans. Lead researcher and engineering professor Bruce E. Logan and his colleagues have combined microbial fuel cells (which can use wastewater and naturally occurring bacteria to generate electricity) and reverse electrodialysis (which creates power from the differences in salt concentration between...

Scientists from Newcastle University in the UK have incorporated the use of a microbe -- usually found high up in the Earth´s stratosphere -- and others found in the UK river estuary, to produce a new source of potential power for the world. The scientists focused their attention on the river Wear estuary, Country Durham, UK to collect and test different bacteria to see which ones had the greatest power-potential. The microbial process is well-established in sewage treatment and water...

Combination generates pure hydrogen gas and desalination facilitated by external power supply Fresh water and reusable energy. Humans are on a constant hunt for a sustainable supply of both. Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Their goal is to find a low-energy-required treatment technology. Researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an...
