Peugeot Expands Use of Rare Earth Based Batteries with First Diesel
I think that one reason that Peugeot chose to go with the rare earth based nickel metal hydride battery for its first-in-class diesel hybrid sedan was, simply, because it still could.
The critical metal in a nickel metal hydride, NiMH, battery is the 2d most abundant of the rare earth metals, lanthanum. A state-of-the-art NiMH battery today, for a vehicle with the size and performance of the Toyota Prius, for example, uses between 12 and 20 kg of (primarily) lanthanum containing some neodymium and a little praseodymium in its overall construction. Additionally the battery uses up to five times as much nickel metal as it does lanthanum and a small amount of cobalt. Thus the manufacturing of a NiMH battery pack requires a lot of rare metals as well as a lot of engineering.

Telstra will sell into broadband loop
The most likely outcome predicted by Mr Guerra was what he termed an ”AssetCo” model, in which Telstra would vend in only some of its copper network, namely ducts and pipes, but would retain ownership of the copper.
He said this was more likely than a ”NetCo” model, in which Telstra would sell in its entire last-mile access, that is, the link between the exchanges and individual homes and offices.
The reason the scaled-back AssetCo model was likely to prevail was government reluctance to buy the copper network as it approaches obsolescence.

Copper Puts the “Power” in Power Tools
“Generally speaking, the more copper mass in the motor, the more powerful the motor is,” explains Deborah Brown, the component design manager for Bosch Tool Corporation. “To increase the power of our motors, manufacturing is challenged to fit more copper wire into the motor.”

Temporary Recession or the End of Growth?
Economic Growth, The Financial Crisis, and Peak Oil
For several years, a swelling subculture of commentators (which includes the present author) has been forecasting a financial crash, basing this prognosis on the assessment that global oil production was about to peak. (2) Our reasoning went like this:
Continual increases in population and consumption cannot continue forever on a finite planet. This is an axiomatic observation with which everyone familiar with the mathematics of compounded arithmetic growth must agree, even if they hedge their agreement with vague references to “substitutability” and “demographic transitions.” (3)
This axiomatic limit to growth means that the rapid expansion in both population and per-capita consumption of resources that has occurred over the past century or two must cease at some particular time. But when is this likely to occur?
The unfairly maligned Limits to Growth studies, published first in 1972 with periodic updates since, have attempted to answer the question with analysis of resource availability and depletion, and multiple scenarios for future population growth and consumption rates. The most pessimistic scenario in 1972 suggested an end of world economic growth around 2015. (4)

ASTM Electrical Conductors Committee Developing New Standard for Annealed Steel Con
August 6, 2009 - ASTM International Committee B01 on Electrical Conductors is developing proposed standard WK24210, which addresses concentric-lay-stranded copper-clad steel conductors. Having standard to reference will increase visibility and viability of CCS and ease evaluation of this alternative to solid copper while ensuring all manufacturers are provided necessary product criteria to meet requirements for grounding applications.

Tin with Copper Clad Aluminum and Magaluma Wire (TCCAM)
Product Description
Copper Clad Aluminum and Magaluma Wire (TCCAM)
The inner conductor of Tinned CCAM is copper clad aluminum and magnesium alloy wire. This type shielding material is processed by tinning on CCAM surface. The electric & mechanical performance is between copper wire and CCAM. It synthesizes copper’s electric conduction nature and light weight and good shielding of the CCAMAdvantage
Compared with tinned copper wire, the length of tinned CCAM is 2.5 times than that of tinned copper wire when their diameters and weight are equal. There is light merit, and saving the cost advantage. Comparing with CCAM. There is solder nature same as copper wire, not like CCAM has to do special treatment.Application
Signal cable shield wire, CATV coaxial cable shield wire, other kinds of shielding wire. -

Electric vehicles will begin shipping in volume starting in 2010. These vehicles will require the rollout of a new infrastructure for charging access at home, at work, and around town. By 2015, access to vehicle charging will be available at more than one million charge points in the United States alone. Vehicles will be primarily charged at home as early adopters will prefer the convenience. China, which has mandated the production of electric vehicles, will be the world leader in charging stations, selling nearly half of the global total of 1.5 million units in 2015. Bidirectional smart vehicle-to-grid charging will remain a niche application for the foreseeable future due to technical difficulties and utilities’ conservative deployment strategies.

Global Market Review Of Vehicle Electrical Wiring Systems - Forecasts To 2016
For manufacturers, the increase in the content and complexity of electrical and electronic components also requires a broader overall design perspective. This shift in design philosophy is, as Lear Corp describes it, “moving from the wire itself to the wire ends”, reflecting a view that design should include both the wiring and the electromechanical and electronic devices to which they are connected.
