Flexible thermoelectric generators could be useful way to make carbon ‘green’. Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other sources into other forms of energy.
The Rice University lab of physicist Junichiro Kono led an effort with scientists at Tokyo Metropolitan University and the Rice-based Carbon Hub to make custom nanotube fibers and test their potential for large-scale applications.
Their small-scale experiments led to a fiber-enhanced, flexible cotton fabric that turned heat energy into...
