By covering a simple piece of paper with ink made of carbon nanotubes and silver nanowires, Stanford researchers were able to create a simple, low-cost battery, which can be used almost anywhere, allowing for many clever applications. Check it out in the video below.

“This technology has potential to be commercialized within a short time,” said Peidong Yang, professor of chemistry at the University of California-Berkeley. “I don’t think it will be limited to just energy storage devices,” he said. “This is potentially a very nice, low-cost, flexible electrode for any electrical device.”
