B. Working Towards an Alternative, Environmentally Friendly Fuel Source

Narrator: This is Science Today. As gas prices continue to soar in parts of the country - the prospect of an alternative, environmentally friendly fuel source is welcome news. And that's just what researchers at the University of California, Berkeley are working on. Tasios Melis, a plant biologist, says he and his colleagues have discovered a way to trigger green algae to produce large quantities of hydrogen gas - a discovery that may greatly impact the future.

Melis: There is a concerted effort by the U.S. Department of Energy to develop what is called now hydrogen technologies. That entails not only the production of hydrogen, but also storage of hydrogen, transportation of hydrogen, utilization of hydrogen to power cars, to generate electricity.

Narrator: So far, the limitations of hydrogen production have been that it's done in a non-renewable manner.

Melis: So I think that's where our contribution is significant, because we have a process based on the biology of green algae and this process permits the production and accumulation of significant amounts of hydrogen.
