This is the Lightest Paint in the World


An energy-saving coating needs no pigments, and it keeps the surface beneath it 30 degrees cooler.

DEBASHIS CHANDA HAD trouble finding a physicist who could paint. The researchers in his nanoscience lab at the University of Central Florida had already worked out the kinks in the high-end machinery needed to create a revolutionary new kind of cooling paint. They had filled vials with vivid colors. But when it came time to show it off, they hit a wall. “We could barely draw a butterfly by hand, which is kind of a kid’s drawing,” says Chanda.

They did it anyway. The shape and the four-color design do look basic, but the simplicity is deceptive. If you zoom in deep—to invisible dimensions—this paint is almost nothing at all like the paint you know.
