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

US speciality brass mill Ansonia Copper and Brass Inc. has announced that it will lay off 85 of the 102 employees at its Liberty Street, Ansonia, factory in Connecticut. The plant manufactures copper alloy rod and wires. Company President Raymond McGee said "it's a very, very difficult situation". He blamed the redundancies, on top of 76 employees laid off in April 2007, on the company's struggle with escalating costs. Since 2002 electricity costs have soared 239%, natural gas 200%, fuel oil 125%, and copper and nickel 500% apiece. Ansonia's other facility in Waterbury, CT, which manufacturers copper alloy tube is unaffected by the announcement.

Further evidence of the impact of the North American economic slowdown on copper demand has recently been published by the ABMS and government statistical bodies. North American copper wirerod production plummeted 9.6% year-on-year to 174,000 tonnes in April. Output had been on a downward trend but the magnitude of the deterioration in April has still come as something of a surprise. A year-on-year increase of 2.0% in North American output January had been followed a 1.0% fall in February and a 2.7% drop in March. In April Canadian output was flat year-on-year due to improving export sales to the US, while US production fell 9.8% year-on-year and Mexican shipments slumped by 17.5%. On a year-to-date basis North American wirerod production was 2.9% lower in the four months to April 2008. Weakening demand from the automotive industry, coupled with a resurgance in copper prices and the return of Russian wirerod imports has clearly led to a deteriorating market situation for domestic mills.

Mueller Industries second quarter results highlight the tough times that the US brass mill industry is facing, but that companies can still operate profitably in a challenging market environment. The company's plumbing and refrigeration segment saw sales fall 11% to US$404m, while its operating profits dropped 32% to US$35m. The company blamed lower shipment volumes and lower spreads for the weaker performance. Sales at the company's OEM division, which includes its brass rod activities, rose 10% year-on-year to US$354m, while its operating profits rose 5% to US$19m. The improvement here is due to acquisition of Extruded Metals. Commenting on the results Harvey Karp, Chairman of Mueller Industries said "Mueller's earnings for the first half of 2008 were achieved despite the continuing decline in the housing industry, the sub-prime mortgage meltdown, the turbulence in the financial markets, rising metal costs, sky-high energy prices and a slowing national economy. Considering these adverse circumstances, we are pleased with the results."

The Yukon Environmental and Socio-Economic Assessment Board (YESAB) has recommended that the controversial Carmacks copper mine project can go ahead, providing that the Western Copper Corporation (TSX: WRN) complies with 148 conditions to mitigate potential adverse impacts. The tiny community of Carmacks with a year-round population of 500 is still considered an important service center for mining and for transportation, a century after it was a popular rest stop for the Yukon gold rush. However, members of the Little Salmon Carmacks First Nation want Western Copper to negotiate a better environmental engineering solution as part of an Impacts Benefits Agreement with the community. Located 38km northwest of the Village of Carmacks and 192 km north of Whitehorse in the Yukon Territory, the Carmacks copper project is planned to be an open-pit operation that will yield about 14,000 tonnes of copper cathode annually. Western Copper has targeted production to begin during the fourth quarter of 2010. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. The YESAB Executive Committee said it was satisfied that: Western Copper adequately consulted with the First Nations in whose territory, and the residents of any community in which the project will be located or might have significant or socio-economic effects; The project proponent provided sufficient information in the project proposal to allow for the assessment of potentially significant effects; Significant adverse environmental or socio-economic project and cumulative effects identified within the scope of the scre

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

It looks ordinary, like a razor-thin metal ribbon. But the high-temperature superconductor power transmission cable the Long Island Power Authority recently installed in Ronkonkoma revolutionizes how electricity is delivered, utility and federal officials said. The cable -- which is a fraction of the size of a traditional copper wire but can carry three times the power -- made its ceremonial debut yesterday with officials from LIPA, the U.S. Department of Energy and officials from the company that makes the cable. It went online April 22, the world's first use of the new technology in a commercial power grid. Utilities around the world are looking at superconductivity to improve efficiency of their grids and make them less vulnerable to blackouts. LIPA has buried three 2,000-foot wires in its right-of-way, and it will be installing a second generation of the wire in the same area as a test. "We view superconductor power cables as an important option that will help us further enhance the reliability of our grid as we meet our customers' increasing demands for electric power," LIPA chief executive Kevin Law said. He said the new cable allows the utility to increase capacity where its system has bottlenecks while increasing reliability and longevity and lowering costs. The wire, manufactured by American Superconductor Corp., conducts 150 times the electricity of the same sized copper wires, strand-for-strand. This means transmission cables can be far smaller and still conduct as much as three to five times more power in a smaller right-of-way.

"Some of Lectromec's conclusions from the data review: One would typically anticipate a high number of failures at the beginning and end of an aircraft's life cycle (component life cycle article here), but incidents for aircraft with less than 10k hours represent only 7% of all reported incidents. Many of the aircraft individually reviewed in the 30 - 40k cycle range were 8 - 10 years old with about 10k cycles. Date of aircraft entering service is not readily available with the data (to be included in future data reviews). If this assumption holds, then most wire incidents around the time of the first aircraft D-check. The most common system to be reported is the emergency path lighting system. Many of the EWIS errors were found during routine service checks. The hazard of these EWIS failures to the aircraft/crew is not easily ascertained from many of the reports. Of the 725 records reviewed: 25 reports identified shorting. 15 reports including detection of smoke - 8 of these were identified as faulty smoke detectors. 5 reports including mention of electrical arcing There were some incidents that were reported to have included smoke/fire. An example of this is the following: "

""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."

Kulicke & Soffa Industries Inc (K&S) has announced that the company has entered into definitive agreements to acquire substantially all of the assets of Orthodyne Electronics Corporation, a supplier of wedge bonders, and sell the K&S wire business unit to WC Heraeus GmbH, a precious metals and technology group. Under the terms of the Orthodyne agreement, K&S will fund the acquisition of Orthodyne with approximately 7.1 million shares of K&S common stock, plus $80 million in cash. If the transaction is not consummated by October 31, 2008, the purchase price will be approximately 19.6 million shares of K&S common stock and no cash. The deal includes possible earn-out consideration up to an additional $40 million in cash if certain financial objectives are met by Orthodyne over the next three years. The closing of the transaction, which is expected within approximately 60 days, is subject to certain working capital adjustments and closing conditions, including regulatory approvals. "The acquisition of Orthodyne is in line with our stated strategy and positions K&S to capitalize on our strengths in equipment manufacturing and further cement our position as the leading supplier of interconnect solutions," commented Scott Kulicke, Chairman and Chief Executive Officer of K&S. "Orthodyne is a fast growing, profitable market leader and provides us with deeper penetration into the discrete side of the semiconductor market, particularly in the attractive power management and hybrid module markets."

Instead, America's consumption binge drew support from two major asset bubbles-property and credit. Courtesy of cheap and freely available credit, in conjunction with record housing price appreciation, consumers tripled the rate of net equity extraction from their homes, from 3 percent of disposable personal income in 2001 to 9 percent in 2006. Only by levering increasingly overvalued homes could Americans go on the biggest consumption binge in modern history. And now those twin bubbles-property and credit-have burst, and so has the US consumption bubble: real consumer spending fell at an unprecedented 3.5 percent average annual rate in the two final quarters of 2008. While the original excesses were made in America, the rest of the world was delighted to go along for the ride. With the United States lacking in internal saving, it had to import surplus savings from abroad in order to grow-and ran massive current-account and trade deficits to attract that capital. This fit perfectly with the macro-imbalances of the export-led developing countries of Asia, whose exports exceeded a record 45 percent of regional GDP in 2007-fully ten percentage points higher than their share ten years earlier, in the depths of the Asian financial crisis. China led the charge, taking its exports from 20 percent, to 40 percent of its GDP over the past seven years alone. The export-led growth in developing Asia could well be described as a second-order bubble-in effect, a derivative of the one in US consumption.

"In the first of a series of exclusive articles, James Gordon explores the latest developments in V2G systems and asks if the technology has the power to reshape global electricity distribution networks.…. It is the world's largest consumer of energy(1), and with over half of China's 1.3 billion population choosing to live in its sprawling and gridlocked super-cities, the demand for power has never been greater. But ensuring that the 680 million who live in China's megalopolises receive a steady stream of electricity is no easy task. However, while the solution - to install a network of long distance super-grids - has proved to be effective, it has come at great cost. This highly innovative smart grid infrastructure that the State Grid Corporation of China, has been specially designed to transmit ultra-high-voltage-direct-current (UHVDC) at over 600,000 volts to China's main population centres from rural areas rich in energy(2). America, India, Germany and Brazil are also incorporating UHDVC lines into their grids, but Britain, whose population is expected to grow from 64,875,165 (2015) to 77,568,588 by 2050(3), is only in the early stages of exploring the potential of the technology according to the Energy Networks Association. And while the UK's Utility giants may yet decide to invest billions of pounds in these high-tech super grids, a fully functioning next-generation Battery Electric Vehicle to Grid (V2G) charging system, located in Birmingham, the UK's second city, may mean they never need to. But how could this potentially game-changing technology, which has been installed at Aston University's European Bioenergy Research Institute (EBRI), one day save the National Grid and the tax-payer billions of pounds?"

Upgrades on Eve of Democratic National Convention's 'Greenest Political Convention in History' Held in Denver\n\nDENVER, CO--(Marketwire - August 22, 2008) - Data393, a Managed Data Holdings Company and a leading provider of colocation, managed hosting, disaster recovery and IP network services, announced today the completion of "Green" initiatives to decrease the facility's carbon footprint. The announcement was made in support of the City of Denver's role as host of the 2008 Democratic National Convention, which is touted as the "greenest political convention in history." Data393's Green initiative also follows in the footsteps of the City of Denver's efforts to leave an enduring legacy of sustainability programs in the Denver metro area. \n\nResulting from the expansion of its multi-million-dollar, 30,000-square-foot data center, Data393 has implemented technological advances and infrastructure upgrades at its Englewood data center, just south of Denver, that reduce its environmental impact. \n\n

Thin-film solar company Nanosolar has been sitting on a big secret for much of this year, it turns out: The company took a $300 million financing this March, and has remained mum ever since, only detailing it on the company's blog this morning after VentureWire reported the funding. While Nanosolar hasn't been entirely secretive about its technology, with chief executive Martin Rosencheisen showing off a rapid manufacturing technique early in summer, but apparently it didn't want details leaking on this giant-sized investment until necessary. Word slipped out in April about $50 million of the total, but at the time, Nanosolar didn't want to talk - and it's now clear why. The race for funds, and ever-larger production targets, is definitely on for thin film. Secretive thin-film silicon company Optisolar has raised over $200 million this year, and Nanosolar's thin-film CIGS competitor Miasole is trying to close on a similar amount. And while dozens of other startups are also on the hunt, large companies like Oerlikon Solar and Applied Materials are pouring money into ventures of their own. In many ways, it looks like an overheated sector. But on the other hand, Optisolar's recent deal with PG&E to provide 550 megawatts of electricity suggests that the potential for thin film panels is larger than previously expected, even when considering one analyst firm's prediction earlier this year that the sector will grow at 45 percent annually. That figure could now be much higher, especially for a few big winners - of which Nanosolar will likely be one. The company will be doing some utility-scale projects of its own, Rosencheisen tells us, with experienced partners. It also has a panel built specifically for use by utilities. And one of the backers of this funding, AES Corp., is also one of the world's biggest power companies. At the moment, Nanosolar is still working toward a gigawatt of annual manufacturing capacity, but it will grow be

The trendspotters at JWT are predicting: - The mobile device as everything hub: Mobile rules. If you're a marketer, take note, made-for-PC sites don't make the cut for a mobile experience. - Customizable mobile: Apple's iPhone made mobile applications all the rage and other smartphone makers are having to follow suit. JWT says watch for more open mobile systems and an "onslaught" of mobile apps. - Decline of email: If you've tried emailing a teen lately you may have noticed that's considered only slightly less old-school than two tin cans and a string when it comes to communications. Text messaging, social networks like Facebook and Twitter are increasingly preferred by email recipients who are ready to cry uncle under the weight of their inboxes. According to JWT, after a decade of dominance, email will gradually be eclipsed by more efficient, manageable solutions. Hear, hear. - Cloud Computing: Software, storage -- everything we needed in our desktop computers or carried around in our laptops is now in the 'cloud.' Wikipedia calls the cloud a metaphor for the Internet, an explanation that is difficult to convey to new users. I found myself trying to explain this to a friend as I was helping her set up a netbook she received as a Christmas present. She wanted to know: Was it on the computer? On a disk? On a USB drive? I just waved my hands in the air and said 'it's all on the Internet now.' That, plus the appearance of 600 of her holiday photos on an online photo site seemed to convince her. - Social networking for jobseekers: With companies handing out more pink slips than Christmas bonuses in the past month or so, jobseekers who know how to maximize the benefits of such sites as LinkedIn and others will find those social networking skills could come in handy. - Web/TV convergence: This prediction has been paraded out in one form or another for quite a while and no telling if 2009 will be its year. The convergence of entertainment media on one viewing device

Top Trends for 2009: On our GloboTrends wiki homepage, we will keep an updated list of global macro trends that we think are the most important to keep an eye on. Some of this list are statistically unlikely to occur, but if they did, it could cause global disruption. These unlikely events were dubbed Black Swan's in a book by Nassim Nicholas Taleb , or might be called the "fat tail" probability in statistics. Others trends we are watching in the GloboTrends wiki are currently ongoing right now (such as our coverage of the credit crisis, deleveraging, margin calls, etc), and we will talk about how they happened, and predict their likely outcome. The format of a wiki makes the document dynamic, so any of our community is welcome to help shape our views of these important developments. Please log in to our wiki, and feel free to comment... In no particular order, here are the global macro trends that we think will be most significant in the coming year (2009): 1. credit crisis of 2007/08 will continue on into 2009...this one is clear...but, how long will it last? how will it fundamentally change international finance? Add your comments to our wiki... 2. fiscal stimulus and crisis recovery 2009 3. deleveraging of Financial markets will continue. In my opinion, this is the most destructive of all the trends. 4. Risk of deflation in the US as Fed Funds target rate approaches zero (other analysts see the opposite risk of potential hyper inflation). Add your comments.. 5. more... add to this list..

ICSG 1 Feb 09 - Based on existing facilities and announced project developments, annual mine production capacity in the period 2009-2013 is expected to grow at an average rate of around 4.3% per year (%/yr) to reach 23.1 Mt in 2013, an increase of around 3.6 Mt (19%) from that in 2009. Of the total increase, copper in concentrate capacity is expected to increase by 2.7Mt (4.3%/yr) to reach 17.9 Mt and solvent extraction-electrowinning (SX-EW) production by 820,000t (4.4%/yr) to reach 5.2 Mt. Most of the new mine projects and expansions are located in Brazil, Chile, Congo, Mongolia, Peru, the United States and Zambia, which together account for around 2.6 Mt (73%) of the projected mine capacity increase during this period. Annual smelter capacity is projected to grow by an average of 2.6%/yr to reach 20.2 Mt in 2013, an increase of 2 Mt (11%) from that in 2009. Asia will be the leading contributor to growth (1.8 Mt), with expansions and new projects expected mostly in China, but also in India, Indonesia and Iran. Africa is the second leading contributor owing to developments in Zambia. North American smelting capacity will fall by 12% (250kt) due to closures of plants in Canada. The ICSG tabulations indicate that world refinery capacity will reach 26.6 Mt in 2013, an increase of 3.2 Mt (13%) from that in 2009. About 2.3 Mt of the expansion is expected to come from electrolytic refineries and 820,000t from electrowinning capacity. Electrolytic refinery capacity growth is projected to average 3.1%/yr, exceeding the projected growth in smelter capacity, and electrowinning capacity growth (at the refinery level) is expected to average 4.3%/yr. About one half (1.5 Mt) of the world refinery capacity increase during this period is expected to come from electrolytic refineries in China; about 25% (830,000 t) from electrolytic capacity increases in India, Indonesia and Iran; and about 20% (600,000 t) from electrowinning capacity increases in Congo, Peru and Zambia.

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.

Monday, 28 July 2008 \nGuangdong Chigo Air Conditioner, a large-sized modern enterprise integrating the development, production and sales of household and commercial air conditioners, recently announced its agent in Egypt successfully won the contract for the Huawei correspondence station in Egypt after seven hardworking months.\n\n Huawei is said to have already achieved 12.56 billion dollars sales revenue, becoming one of the top five global telecommunications equipment producer, now with primacy globally, especially in Africa. Contracts for the correspondence station of Huawei in Egypt were mainly in the hands of Carrier for a long time, which means other brands could not compete with it and usually did not pass the test phase. Because the equipment for each station was valued at over 300 thousand yuan, the AC units could not run for a long time without a reliable capability guarantee. Right now the first set of Chigo splits is already installed in the station.\n\nThe vice president of Chigo Overseas Marketing Department , Mr. Peter Liao, said :"The success of this project means a lot for us. The intergrated ability of Chigo is already at new stage, being the supplier of a globally famous communication company. The cooperation with Huawei is meaningful for Chigo's development in the North African and African markets." For the success of the Huawei project, Huawei's subsidiaries in Libya and Sudan have also started to cooperate with Chigo, reveals the company's press release. \n\n\n
