This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

""We have developed several new solutions, which can provide clear weight and cost saving opportunities to manufacturers of such commercial vehicles as trucks, buses as well as agricultural, industrial and construction equipment", stated Dr Andreas Brand, member of Leoni AG's Management Board with responsibility for the Wiring Systems Division. "We are confident that we will grow our business with the CV industry by more than five per cent per year until 2025." Alternative conductors save weight and cost In terms of weight optimisation, Leoni can reduce the harnesses' weight by replacing conventional wires. Alongside copper wires with smaller cross-sections, the Company provides the CV market with a range of wires made of aluminium for the power segment, i.e. with a cross-section between 10 mm2 and 110 mm2 and even larger. Although the aluminium conductors have a larger cross-section in order to deliver the same electrical conductivity, aluminium technology results in a noticeable weight reduction. On its booth, Leoni will show its busbar, a solid aluminium conductor, which can be bent in three dimensions and weighs only about half as much as the conventional copper component. Leoni will also show various conductor solutions based on copper. These can be used where mechanical strength as well as electrical conductivity is required. For example, a copper wire with a cross-section of 0.75 mm² could potentially be replaced by a smaller wire cross section, such as a 0.50 mm² or a 0.35 mm². Thanks to the use of less conductor material, Leoni's customers can not just reduce the weight of their vehicles, but also benefit in terms of cost savings."

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

"In the near term, the Chinese economy is pausing for breath. China is not completely insulated from an OECD recession and we will see an impact on Chinese exports. However, the near term slowdown of growth is substantially due to tightening of monetary policy introduced by the Chinese government last year in order to tackle inflation. Furthermore, we expect third quarter economic data to show an exaggerated slowdown, reflecting the postponement of projects during the Olympics. Looking further out, Chinese GDP will remain largely driven by the domestic economy and we expect industrialisation and urbanisation to continue apace with strengthening demand across a range of Rio Tinto products.

That plastic pipe systems continue to gain market share through supplanting competing pipe materials such as copper, concrete and steel due to easy and low cost installation as well as long term performance, Stephen Boros who is also VP Engineering for Pipelines Plastics, LLC explained. "In North America, these inherent advantages are now further supported by the development of the shale oil and gas industry. This development not only benefits the energy market but also represents a more secure long‐term supply and cost advantage from a power costs to raw materials stand point. Technology transfer will undoubtedly propel the growth of demand for plastic pipe systems in other world markets."

"In economic terms what are the substitutes and compliments to copper? "

"In this infographic, we examine long-term trends and the outlook for copper supply."

SYDNEY -(Dow Jones)- BHP Billiton Ltd. (BHP.AU) said Tuesday it expects stainless steel demand to be robust over the long-term, underpinned by China's ongoing urbanization and industrialization, the miner said in a presentation to analysts on a site tour at its nickel operations in Western Australia.

KGHM, a Polish copper producer, expects demand for copper will be largely affected by China. The company anticipates that long term copper prices will be strong; however, the short to medium term outlook is impacted by China's tighter monetary policy.

An official from SDI La Farga LLC's said on 11th December that the company is producing limited amounts of wirerod at its new US $39M plant in New Haven, Indiana. The new facility, a joint venture between Spain's La Farga Group and Steel Dynamics Inc, produces wirerod from number 2 scrap copper rather than cathode. The company official said "we've produced quality rod and are in the process of getting approval of customers and we have done so with several customers." He added that plant officials are "waiting for more customer orders to start producing more".

Anhui Jincheng, the Shanghai-listed producer of copper PSSF, said on 26th March that it produced 93,872t of copper PSSF in 2012, a 13% y-o-y increase from 2011. Despite the increase in output, the company made a net loss of RMB57M in 2012 from a profit of RMB24M in 2011 (loss of US$9M from a profit of US$3.8M). Remarking on the results the company said that "uncertainties in the global economy, the euro debt crisis, plus the weak Chinese economy, has negatively impacted demand by the downstream processing sector last year."

Talking at the annual CESCO/CRU World Copper Conference, CRU Principal Consultant Vivienne Lloyd said that up to 2Mt of copper demand could be lost over the next five years due to substitution and consolidation amongst Chinese semis producers. Lloyd said that the areas under the greatest threat from substitution are the automotive wiring harness sector and the HVAC sector. However, CRU believes that the aluminium/copper price ratio is likely to have peaked in 2012 at around 4:1, and will fall back gradually to 2017 reaching 3:1, which should relieve some of the substitution pressures.

Light weighting as a strategy to combat emission and mileage targets has carved a niche corner in automotive original equipment manufacturers' (OEMs') and supplier's research and development. Almost all OEMs have been working on ambitious weight reduction strategies to adhere to future regulations. Light weighting has a profound effect as a long-term strategy, as OEMs transit from making ICE-powered vehicles to battery electric and fuel-cell vehicles. Light weighting as a strategy has implications in other industries such as aviation and power generation. This market insight provides insights on the key factors such as emissions, mileage targets, emission test cycles, electrification, urbanization, and cost and their influence on OEM light weighting strategies.

"Substitution of raw materials likely to increase next year"

"The transition to a more decentralised and intelligent energy system will continue in 2017, driven by the continued regulatory support for renewable energy in a number of key markets. The 3 Ds of energy are driving future investment - increased decentralisation, the need to decarbonise electricity generation, and digitisation to boost the sector's operational efficiency and open up new market opportunities. The highest growth rates will be for solar PV, with investment forecast to increase by 11.5% to €141.6 billion in 2017. China continues to be the largest market in terms of revenue investment, but the fastest growth will come from India, which will see double-digit growth in investment to 2020. New business models that incentivise smarter consumption patterns, and the growth of energy storage technologies, will increasingly reduce the need for peak capacity investment in mature energy markets."
