Rice University researchers create spray-on battery, powered bathroom tiles

Liquid solar cells are pretty neat, to be sure, but current-generating paint can be a hard color to match. Good thing, then, that researchers at Rice university have developed the perfect complement: a spray-on battery. By carefully layering five coats of specially formulated paint, the team has found a way to apply a thin coat of lithium ion storage to multiple surfaces, including glass, ceramics, steel and flexible polymer
