It's a promising new technology that you'll learn about on today's EnvironMinute. Anyone downwind of a sewage plant doesn't need to be reminded of this fact. Most sewage plants just burn off the excess methane. It works, but the unfortunate side effects not only stink, they contribute to global warming. Now a new technology uses methane in a fuel cell.
Fuel cells create electricity from chemical reactions, without any kind of combustion.
Fuel cells are now operating at wastewater plants in New York and Boston where their arrival is a breath of fresh air. The EnvironMinute is produced in cooperation with the National Safety Council and made possible by the Teresa and H. John Heinz III Foundation.
