Carbon-Dipped Paper (IMAGE) University at Buffalo Caption A central component of the new technology is a sheet of carbon-dipped paper folded into an upside-down "V." The paper's sloped geometry keeps it cool by weakening the intensity of light illuminating it. (A flat surface would be hit directly by the sun.) This novel, slanted architecture helped to speed vapor and water generation in experiments.
