Powering the Future
Many researchers believe that fuel cells will be the power sources of the future. They are more efficient than the internal combustion engine, have no moving parts, and produce almost no pollution. One day they may power our vehicles, our offices, and even our homes. This morning on Focus we're joined by Scott Barnett from Northwestern University to explore the basics of the fuel cell: how it works and some of its potential applications.
