Solar Nanotechnology Arrives
After decades of fits and starts, solar energy gets a boost from some new technology emerging from the Silicon Valley. Offering the promise of mass-produced light-collecting plastics that could be embedded in building materials or spread across rooftops, the nanotechnology firms involved in this pursuit are confident that costs can easily be reduced to levels similar to non-renewable sources of energy. Freedom from the grid may be near at hand.
