Fuel Cell Cleans Pollution and Makes Electricity

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.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America move closer to, or further from, justice and equity in the years to come?

If you're able to, please join us in this mission with a donation today. Our reporting right now is focused on voting rights and election security, corruption, disinformation, racial and gender equity, and the climate crisis. We can’t do it without the support of readers like you, and we need to give it everything we've got between now and November. Thank you.
