“Artificial Leaves” Generate Energy

This is pretty cool. New techniques have been developed to transmute leaves’ natural chlorophyll into titanium which is then used to generate hydrogen. While the chemical transformation is important in the process, it is the leaves’ natural complex nanostructures which are so efficient in catching light and generating energy. In fact, the leaves do this much better than a commercially available titanium product called P25. (New Scientist, January 9th, 2010)
