European team announces superconductivity breakthrough

European researchers said Tuesday they had developed a cheaper and more efficient superconducting tape which could one day be used to double the potency of wind turbines.Eurotapes, a European research project on superconductivity -- the ability of certain materials to channel electricity with zero resistance and very little power loss -- has produced 600 metres (1,968 feet) of the tape, said the coordinator of the project, Xavier Obradors, of the Institute of Materials Science of Barcelona."This
