EcoVolt generates energy from wastewater

The video discusses the potential of turning wastewater into energy using microbial fuel cells. Environmental engineer Bruce Logan and his team at Penn State are developing this technology, which uses bacteria to convert organic waste into electricity. The process involves microbial fuel cells that channel the bacteria's work into energy. The team is working on making the technology cost-effective by using cheaper materials. Future prospects include using saltwater to generate more electricity and potentially powering entire wastewater treatment plants.
