        NOVA ScienceNOW: Solar Paint Your Roof

        In this video segment adapted from NOVA, learn about a new solar technology being developed to make solar electricity more affordable. Nathan Lewis, a chemist at the California Institute of Technology, describes how nanotechnology can be used to capture the energy from sunlight in new ways. Investigate how solar paint technology, using titanium dioxide processed into nanotubes, could convert sunlight into electricity using relatively cheap materials and offer a solution to the global energy crisis. Hear about early tests of the new technology and how it needs to be further developed.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
