"Researchers at the Massachusetts Institute of Technology say they have used spinach to harness a plant's ability to convert sunlight into energy for the first time, creating a device that may one day power laptops, mobile phones and more," reports AP.
"A top layer of glass was coated underneath with a conductive material and a thin layer of gold to aid the chemical reaction. In the middle, the spinach-peptide mixture sits on a soft, organic semiconductor that prevents electrical shorts and protects the protein complexes from a bottom layer of metal. By shining laser light on the "sandwich," researchers were able to generate a tiny current. While one device by itself can't generate much energy, billions of them together could produce enough electricity to power a device."
