A team from Guizhou Institute of Technology is working on a way to turn eggshells into a data-storage device that could pave the way for eco-friendlier computers. The eggshell-based device is able to write 100 bits into its memory before it breaks down. The scientists pulverized the shells for hours into an ultra-fine powder which was then dissolved in solution. The resulting paste, coated onto a substrate, became the electrolyte portion of a memory chip, which is the part that carries the electrical charge.
