a new nanowire promises to revolutionalize the world of nanotechnology. Developed by scientists at Harvard University, the wire, which is a fraction of the width of human hair, will function as a solar cell, generating power for its own use, and other nanodevices.

Scientists say the nanowire is more efficient than solar devices but not enough for large-scale power generation yet. Unlike older nanoscale solar cells made of a combination of organic and inorganic materials, the new solar cell is purely inorganic
