Carbon nanotube solar funnel as powerful solar array

By / September 13, 2010

This filament containing about 30 million carbon nanotubes absorbs energy from the sun as photons and then re-emits photons of lower energy, creating the fluorescence seen here. The red regions indicate highest energy intensity, and green and blue are lower intensity. (Credit: Geraldine Paulus/MIT.) MIT News reports that chemical engineers have devised a way to…
