Nature has been developing her technologies for many hundreds of millions of years, said Ray Baughman. "By looking at the way in which nature has solved problems like muscles, we can advance our own technologies." Baughman is director of the NanoTech Institute at the University of Texas at Dallas. His lab creates very tiny artificial muscles by spinning filaments of invisibly small carbon nanotubes into an extraordinary yarn. Pound for pound, this nano-yarn is stronger than steel -- yet is so light it almost floats in air. This interview is part of a special EarthSky series, Biomimicry: Nature of Innovation, produced in partnership with Fast Company and sponsored by Dow. Baughman spoke with EarthSky's Jorge Salazar.
