National Science Foundation: Green Revolution: Hydrogen

Lisa Van Pay of the National Science Foundation visits scientists at MIT as they take on the hydrogen energy challenge. Hydrogen bonds are an extremely efficient way to store energy, and scientists would like to capture this energy. Unlike other fuel sources, hydrogen can't be harvested easily as most of it escapes from the atmosphere, so we have to make it, which uses a lot of energy. In the future, people could be able to power their entire house and their car using hydrogen fuel cells without damaging the environment. [6:10]
