Nanotechnology provides a cost-effective way to improve performance of thermoelectric materials
Although we are great fans of atomically precise nanotechnology, sometimes random nanostructures can be surprisingly useful. An economical nanotech procedure—ball milling followed by hot pressing—recasts a commercially available material as a composite of random nanostructures that efficiently converts waste heat into electricity. Excerpts from a report by Katherine Bourzacat at Technology Review: “Cheap, Efficient Thermoelectrics: Nanomaterials could be used for lower-emission cars and solar p
