Microbiologists at the University of Birmingham in the UK have developed fuel cells that are powered by feeding chocolate factory waste to sugar-loving bacteria. In testing, Escherichia coli bacteria dismantled caramel and nougat waste, producing organic acids and a form of hydrogen. The hydrogen was localized and used to power a fuel cell, which drove a small electric fan. This technology has additional environmental benefits since the caramel and nougat waste usually ends up in landfills. That's right, landfills are full of caramel and nougat deliciousness. Write that on a candy wrapper and slide it under your unemployed roommate's bedroom door. Problem solved.
