Myth No. 1: Copper is the only conductor material for use in wind turbines. Reality: Traditionally, cable and wire manufacturers have used copper as the conductor material of choice for cables used throughout wind turbines. However, with copper prices being extremely volatile due to varying degrees of demand, cable research and development engineers use alternative conductor materials or copper alloys that perform comparably to pure copper when they can to combat the effects of copper’s changing price in order to keep turbine costs under budget.

High-performance, low-cost passive copper cabling remains the preferred alternative for short-reach applications in the data center. However, standard round copper cables can be bulky and consume precious space. A recent innovation in manufacturing technology by 3M has resulted in the development of a uniquely shielded, thin, ribbon-style copper cable. The cable has the ability to fold multiple times and maintain signal integrity, allowing for higher-density racks and space savings. A major barrier to decreasing the size and stiffness of a round cable is inherent in the construction of traditional cable. This is an issue because a round copper cable can extend up to nine inches when routed behind a cabinet. In conventional, twin axial constructions, the shield is applied by wrapping it spirally around the insulated wire pair. This layer is then overwrapped to provide support and retain the primary shield wrap, increasing the stiffness of the pair. Multiple pairs are then cabled and an overall foil and braided shield are typically applied, thus further increasing the cable bulk and stiffness.

Here we demonstrate a new material design in the form of a nanolayered composite consisting of alternating layers of metal (copper or nickel) and monolayer graphene that has ultra-high strengths of 1.5 and 4.0 GPa for copper–graphene with 70-nm repeat layer spacing and nickel–graphene with 100-nm repeat layer spacing, respectively.

February 2010—Siemon now offers 40+Gb/s SFF-8470 4X Passive Copper cabling products. These SFF-8470 copper cable assemblies support high-speed interconnect applications such as high-performance computing (HPC), enterprise networking, and network storage systems. The low latency assemblies support data transfer rates from 2.5Gb/s to 10+ Gb/s per lane. Siemon’s 8470 cable assemblies feature a shielded wafer construction in which the signal conductors are directly attached to the connector’s contacts, eliminating a printed circuit board and enhancing noise-resistance to maximize signal integrity. The twin-axial shielded cable conductors are laser-welded, reducing cross-talk and jitter to support 10+Gb/s data rates. SFF-8470 die cast back shells and latches are interoperable with all compliant interfaces. The 8470 product supports a wide array of data protocols and interfaces, including InfiniBand SDR, DDR, and QDR, Ethernet 10GBaseCX4, and 40GBaseCR4. These cables also support FibreChannel, RapidIO, Myrinet, SAS, SATA, Aurora, VITA VXS, and XAUI/XAUI-2 IO interface links, as well as SONET/SDH. Product options include 24 to 30 wire gauges and various assembly lengths.

But signs of a broader recovery are harder to spot in sectors such as automotive, where carmakers are cutting back output in the face of dismal sales figures, the latest of which this week saw the market contract by about a quarter during February compared with the year before. Such reductions are, in turn, having a knock-on effect in sectors including steel, with large producers such as Tata Steel and Steel Authority of India, the nation’s two largest by sales, unveiling unexpectedly disappointing results during the past quarter. Tuesday’s data also showed further declines for companies in the country’s battered extractive industries, where recent production bans in big mining states have forced operations at companies such as the iron ore arm of London-listed Vedanta Resources to all but stop completely, pending legal reviews.

Joe Kava, the company’s head of data centre operations, has warned that water is “the big elephant in the room” for tech companies, which can typically use hundreds of thousands of gallons of water a day. “We’ve been focusing on power consumption and energy efficiency and that’s excellent,” he said in 2009. “I think the next thing we need to turn our attention to is what do we do about the looming water crisis?” As water becomes more scarce, data companies’ use of it could attract public scrutiny, he added, possibly resulting in regulations governing how much water they consume.
