A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind \u201cpyroelectric nanogenerator\u201d is the topic of a report in ACS\u2019 journal Nano Letters.
