Researchers at the University of Texas and Hanyang University in South Korea have developed a high-tech yarn that generates electricity when twisted or stretched. The yarn is made from carbon nanotubes, which are hollow cylinders of carbon, 10,000 times smaller in diameter than a human hair. In their experiments, they found that twisting the nanotube yarns caused them to generate electricity.

The technology could be used to harvest energy from the motion of ocean waves, among other applications.
