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.

  it also seems that with super conductors, you can "freeze" a magnetic field (configuration) to your liking:

  it seems possible to "charge" a super conductor with a current (amps) then loop it back
  onto itself (like a real loop), remove the current source and voila, the current keeps circling inside the super conductor (and is the source of a magnetic field!).

  thus, you don't need to dig out chinese neodymium and then cast it into complex shapes and then "magnetize" it
  into a permanent magnet form.

  rather you take the super-wire, bend it into the shape you want it to emit a magnetic field from, cool it down and then do the
  amp charging trick and loop-back-onto-itself thingy, remove the charge source and voila you turned a super-conducting loop into a
  a permanent magnet that only needs to stay cooled to remain a strong, easily formed "permanent magnet"?

  thus the "stator" or rotor, whatever, doesn't need to constantly be feed with current but rather is like a generator or motor with permanent magnets?

  pretty awesome .. alink between "magnetic field source" and
