Nanotechnology Doing Double-Duty

Interesting find at WorldChanging:

Researchers from Pennsylvania State University have constructed a material made from titanium dioxide nanotubes that is 97 percent efficient at harvesting the ultraviolet portion of the sun’s light and 6.8 percent efficient at extracting hydrogen from water.The material is easy to make, inexpensive, and photochemically stable, according to the researchers.

While they still have glitches to overcome, it’s looking like there may be greener methods available to extract hydrogen…
