071203120753.jpgPennsylvania State University environmental engineers have developed a fuel cell that uses pollution from coal and metal mines to generate electricity. Bruce E. Logan and colleagues describe successful tests of a lab-scale fuel cell based on microbial fuel cells capable of generating electricity from wastewater. Their device removes dissolved iron from solution while generating electricity at power levels similar to conventional microbial fuel cells (the recovered iron can be used in paints or other products). Better yet, the researchers say, later generations of these cells will lead to more efficient power generation in the future.

Engineers may save us yet.

Fact:

In-depth journalism that investigates the powerful takes real money and is so damn important right now.But it doesn’t take a Mother Jones investigation to know that billionaires and corporations will never fund the type of reporting (like they do politicians) we do that exists to help bring about change. Instead, our mission-driven journalism is made possible by people power, and has been for 46 years now since our founding as a non-profit.

In “TITLE TK” Monica Bauerlein writes about the perilous moment we’re in, and why it’s so important that we raise $325,000 by the time November’s midterms are decided so we can be ready to throw everything we have at the big issues facing the nation no matter what happens.
