Pennsylvania (TGW) - Scientists in Pennsylvania have developed a fuel cell which uses pollution from coal and metal mines as a source of energy.
The fuel cell could solve a major pollution problem, acid-mine drainage. Acid-mine drainage is hard to clean up and affects the safety of the water supply.
The fuel cell is based on microbial fuel cells, which are capable of generating electricity from wastewater.
In lab experiments, they show the fuel cell can remove iron while generating electricity from a solution similar to acid-mine drainage.
