The article reports that Rachel Segalman, an assistant professor of chemical engineering at the University of California in Berkeley, has discovered that cheap organic molecules can be used to generate electricity from heat. It is indicated that most of the heat energy lost in fuels could be converted to electricity by thermoelectric materials. She and her colleagues are modifying the molecules and inventing new devices that could harness electricity. It is noted that the devices could harvest hat in computers to extend laptop battery life.
