But if nature was forced to use the pipes-and-ion-channels approach, that leaves us with plenty of scope for speeding things up using silicon and copper (and this is quite apart from all the other more exotic computing substrates that are now on the horizon).  If we were simply to make a transition membrane depolarization waves to silicon and copper, and if this produced a 1,000x speedup (a conservative estimate, given the intrinsic difference between the two forms of signalling), this would be an explosion worthy of the name.

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.

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.

According to Lima-based Kallpa Securities Managing Director Ricardo Carrión and President Alberto Arispe, recent government actions might signal a reset, with the government even acting as a mediator between mining companies and the local communities. In this interview with The Gold Report, Carrión and Arispe detail the state of mining exploration in Peru and discuss companies actively exploring, including one that just received its long-awaited environmental approval.

As cable harnesses are already among the most complex and heaviest components used in vehicles, any possibility for weight savings is an attractive proposition. A model calculation of realistic weight-saving potential was analyzed in an average mid-size car with a cable harness weighing just under 30 kilograms. For the substitution of Al wire for Cu conductors, exclusively larger cross-sections (>0.75 mm²) were analyzed, excluding the fine-signal conductors. Al conductors with the next-highest cross-section replaced the affected Cu conductors. Under these conditions, a purely computational weight savings of around 7kg was initially achieved. However, for the last decade in Germany, the solid battery terminals were already made of Al, so the actual potential for savings in this particular case study is 2-3kg per cable harness.
