(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
When Mike Arnold thinks about solar energy, he thinks big, as in the "more than one-hundred-million-billion watts of sunlight that the Earth continuously bathes in." But he also thinks very, very small, exploring how a one-billionth-of-a-meter ...
