Rust brings boost to solar energy potential: scientists (3:26) 

Feb. 8 - Using the power of sunlight, Swiss scientists are developing methods of extracting inexpensive, safely transportable, hydrogen fuel from iron oxide - commonly known as rust. The process essentially converts solar power into hydrogen, vastly increasing the potential of solar energy to serve as a viable renewable energy source across the world. Jim Drury met the scientists behind the research. ( Transcript )
