Could bacteria which feed on wastewater and vinegar produce a hydrogen fuel we can use to drive our cars? Well according to some researchers at Penn State University, the answer could be “yes.” As reported in the Environmental News Network, these scientists have developed “microbial fuel cells” that can turn almost any biodegradable organic material into zero-emission hydrogen gas fuel. The process utilizes a bacteria which slurps up acetic acids and generates small amounts of electricity. When just a touch more electricity is added to the process from an outside source, hydrogen gas bubbles up from the liquid and the only emission produced is water. With fuel prices soaring, sounds like a breakthrough we can all get gassed up about!
