“We want to see this process used,” Larbalestier said. “We want to build lots of magnets out of Bi-2212, get the wire cost down, useable lengths way up and make Bi-2212 the precursor of new generations of round, twisted, multifilament, high-temperature superconductor wires that will be revolutionize superconducting applications.”

"The use of copper - which is much cheaper and more abundant - as an alternative electrode material to silver would dramatically reduce the cost of these nanowire materials. Despite these advantages, copper nanowire conductors face a serious bottleneck for future practical use in flexible and stretchable optoelectronics: although they are nearly as conductive as silver, this conductivity is not stable. Researchers have now demonstrated conductive copper nanowire elastomer composites with ultrahigh performance stability against oxidation, bending, stretching, and twisting. This material offers a promising alternative as electrodes for flexible and stretchable optoelectronics. "

I've been travelling around Broadband Britain with a whole lot of clutter in my suitcase - three phones, two computers, an SLR camera, three USB mobile broadband dongles, a digital radio recorder and two microphones. But buried in my bag are two lengths of cable - one traditional twisted pair copper telephone wire and one fibre-optic cable,

14 January—NASA has opted for copper over optical fiber for connecting components in the next-generation space telescope. In a situation somewhat akin to telecom operators' widespread use of DSL technology instead of fiber optics for broadband service, the James Webb Space Telescope (JWST) will use advanced twisted-pair technology to bridge instruments and electronic components across it's tennis-court-size frame, according to NASA.

According to Penn State engineers, transmission rates of 100 gigabits per second are possible today over copper. But only on distances of less than 100 meters. And only with high-end Category 7 copper cables. These Ethernet cables are made up of four pairs of twisted wires shielded to reduce crosstalk. The Penn State technology could provide an alternative to glass fiber optics cables in computer datacenters where distances between systems are not too big. In other words, it would be possible to interconnect servers inside a building at speeds similar to the ones provided by more expensive fiber optic cabling.
