Nano-engineering boosts efficiency of materials that convert waste heat to electrical energy

( University of Michigan ) High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale in places like power plants or military bases, researchers say.Source:
