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 material, a copper oxide, is like a thread that conducts 100 times more electricity than copper. With this thread you can for example make cables to transport much more electricity or generate much more intense magnetic fields than today," he told AFP.
"This new material could be used to make more potent and lighter wind turbines," he added, predicting it will make it possible to manufacture wind turbines one day with double the potency than existing ones.
No graphene was involved in this announcement.

No direct power loss in the superconductor due to resistance, but any time you move any conducting object into or out of the magnetic field generated by the current you will get some power loss due to induced currents in the object. With decent design, this loss is far less than is lost in resistive conductors.
No problem is insoluble, but at Ksp = 2.943×10−25 Mercury Sulphide comes close.
