Nanotechnologists have recently succeeded in their attempts to build molecular systems based on highly efficient versions of the molecular "machine" that plants use to turn sunlight into energy. Such molecular-assembly machines could be used in many applications, including sensors and other electronic devices.
This breakthrough might also have something to say about our recent discussion of the difficulties surrounding using hydrogen as an energy source.
Working with researchers at the University of New Mexico's Center for Microengineered Materials, Sandia scientist John Shelnutt has created convoluted platinum structures that might be used to split hydrogen atoms from water molecules, leading to a light-driven source of hydrogen.
