A paper published in Nature Materials this week details a new method for using nanotubes to generate significant amounts of power, at least for their size. When multi-walled carbon nanotubes are covered with a material that produces an exothermic reaction, the nanotubes help conduct the heat in one focused direction. To the apparent surprise of the researchers, this created an electrical pulse, a quick surge of power, that could be put to a number of uses. When you couple a heat-activated material with...
