(AFP)- Japanese scientists at a boozy office party stumbled across a discovery they hope will help revolutionise efficient energy transmission one day: red wine makes a metal compound superconductive. The researchers plan to showcase their surprise findings later this year, the 100th anniversary of the discovery of the phenomenon of superconductivity, the zero-loss flow of electricity through certain materials. The "eureka" moment came when National Institute for Materials Science researchers found that an iron-based compound became superconductive after being soaked in alcoholic drinks such as beer, wine and sake.
