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."

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.

Figure 8.2.2.1 illustrates the lengths of subsea cable that may be required year by year. It is based on expected device spacings, farm layouts and likely distances from offshore substaons to shore. The final lengths required will depend on exact site layouts and separaon distances between devices as well as the method of connecon between devices, which could have dedicated connecons to the transformer or be chained together. The chart has the same profile as that of the number of devices installed, but offset as cables are purchased in advance of installaon. Export cables installed as part of a project's inial phase may be specified with sufficient capacity to accommodate later phases as well.

Companies would spend more than $6-billion on submarine and terrestrial fibre optic cable infrastructure projects in Africa over the next two years, as countries scramble to boost international connectivity, market analysis firm BMI-TechKnowledge (BMI-T) said on Wednesday. In its latest research report, entitled 'Outlook for submarine and terrestrial fibre-optic cable developments in Africa', BMI-T said that the effective high-speed internet services required for critical business, government and consumer applications have remained either unavailable or very expensive in Africa. Governments' awareness of this situation, and the perceived commercial attractiveness of the opportunity to close this gap, has given rise to the current frenetic activity for construction of submarine fibre cables on the continent. Investment in Africa's ICT infrastructure has improved significantly over the past decade. However, marked deficiencies persist in the backbone networks across the continent. "Although countries on the African west and southern coasts have access to fibre connectivity through the SAT-3 undersea cable, an estimated 80% of Africa's international voice and data traffic is carried via satellite," said Chanakira.

A strike planned to start on Monday at Southern Copper's Peruvian mine Cuajone has been temporarily suspended pending mediation, officials from the company and union said. Southern, one of the world's largest copper producers, has been hit by strikes this year in Peru as workers demand a larger slice of the country's economic boom. Union leaders had planned to go on strike again because the company had threatened to fire about a dozen workers for participating in recent walkouts. But Roman More, head of the union at Cuajone, said the strike slated for Monday was called off as the company agreed to sit down with workers and the government for talks on Tuesday. Unions from the company's Ilo smelter and Toquepala mine were also expected to participate. "We are going to meet on Tuesday to see if we can reach an agreement about the firings. The meetings were requested by the government," More said. Alberto Giles, the company's human resources director, said the strike plans were scrapped. "In the case of Cuajone ... they suspended the strike plan," he said. "With regards to Ilo, the strike was supposed to start on Wednesday, but I don't think there will be a strike. I think the strike will also be canceled at Ilo." Cuajone, which produced some 148,939 tonnes of copper last year, is Southern's biggest mine in Peru, the world's No. 2 copper producer.

A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and the air conditioner. This eliminates the power losses associated with converting AC to DC

GreenCore units are being tested by a McDonald's restaurant and the U.S. Navy.

The battery technology for plug-in HEVs and EVs (both fixed and removable) has evolved tremendously over the last decade with the introduction of lithium-based batteries complementing lead-, nickel- and sodium-based technologies. These technologies will all continue to have a significant impact on electro-mobility as they may give cost and/or performance advantages for specific applications, for example as start-stop and hybrid solutions. The selection of a technology depends on the requirements for performance, life and cost for a given application. Given the diversity of possible operating modes, there is no one battery system or technology that covers the entire range of application needs sufficiently. On the contrary, different battery energy storage technologies exist and each of them has a role to play in the future as the best solution to the needs of a system depending on their specific attributes: * Lead-based: for start-stop micro application, up to mild HEVs * Nickel-based: for HEV applications only * Lithium-based: for HEV, plug-in HEV and full EVs * Sodium-based: for Plug-in HEV and full EVs

Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

Despite a slowdown in the global economy and a softening in demand for aluminium rolled products in some regions, JSE-listed aluminium reroller Hulamin expected global demand to increase this year. CEO Alan Fourie on Tuesday commented that the company, which exported about 70% of its products, had seen some softening in demand for aluminium rolled products in some regions, but added that demand for these products was expected to grow by between 5% and 7% this year. "Obviously the slowdown of the [global] economy puts pressure on margins, it is an economic consequence, but we are still selling into a growing international market," he said. Locally, however, the softening economic climate was expected to impact on sales volumes for the second half of the year. However, Hulamin expected these high-value products to continue growing as a percentage of its sales in the next few years. Fourie noted that five years ago, these products equated to just over 50% of its sales volumes, while their contribution was just below 60% in 2007. They now comprised about 64% of its total sales volumes. Meanwhile, Hulamin stated that its costs had increased by 16%, influenced by a 58% increase in energy costs, increasing alloying costs caused by magnesium prices rising from $2 000/t to $4 500/t, and increases in other metals. Excluding the cost of increasing energy and metals prices, the company's costs had increased by 6%. Fourie noted that while the rising aluminium costs did not affect its profitability, it did have an effect on its working capital. "We hold aluminium in our working capital. So when the aluminium price increases, the cash tied up in working capital increases and we have seen a significant increase in working capital during this period, because the rand price of aluminium has increased by close to 40% in the last six months," he explained. Further, Fourie did not expect the increasing electricity prices to have too great an impact on its futu

"Airbus selects Nexans as main cable supplier for the next 5 years The new global supply contract, which builds on Nexans' existing 20-year partnership with Airbus, covers the supply of the hook-up, power, data and fire resistant cables that represent some 95 percent of the total cable requirement on an aircraft. The exact amount of cables on each aircraft varies according to its specification, from 200 km to 600 km depending on the aircraft model. Weight saving is a major priority for Airbus and a crucial element in winning this contract was Nexans' innovative approach to lighter weight cable designs with no compromise on safety, performance or reliability." The A380 jet uses aluminum wire and cable.

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.

The redeveloped World Trade Center will be "one of the largest fuel cell installations in the world" according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. "Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson's leadership to combat greenhouse gas emissions and diversify the state's energy mix. To date, we've installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor's ambitious goals for significant increases in the state's renewable power," says Roger B Kelley, NYPA President and Chief Executive Officer.

There is no consensus among the analysts on Inmet Mining Corp.'s (IEMMF.PK) C$345-million hostile bid to take out its junior partner Petaquilla Copper Ltd. (PTQLF.PK). On the positive side, Raymond James analyst Tom Meyer wrote that by moving its stake in the Petaquilla copper project from 48% to 74%, Inmet would gain "important strategic flexibility" and lower the risk profile on the project. If Petaquilla Copper was bought out, Inmet and Teck Cominco Ltd. (TCK) would be the sole remaining partners and the legal action between Petaquilla Copper and Teck would presumably end. In a note, Mr. Meyer wrote: With two shareholders in the project as opposed to three, we believe it is safe to say that rational decision-making may likely become less of a bottleneck and the project can move forward at a faster rate. He added that by going to a 74% interest, Inmet could be in a position to potentially buy Teck Cominco's stake as well. Analyst Greg Barnes from TD Newcrest presents the negative view. He wrote that the economics of the Petaquilla project are "marginal" and figures that it would need a long-term copper price above $2.25 a pound for it to work. He also noted a "lack of clarity" on how Inmet could optimize value from the project. He wrote: Until Inmet is able to verify improved project parameters, we feel that the company is overpaying for a project that has less than compelling economics. Over at UBS Securities, analyst Onno Rutten's opinion is a little more mixed. He thinks that Inmet's C$2.00-a-share offer for Petaquilla Copper is "a steep premium," but would accelerate the project's development if it is successful. That could unlock value for Inmet. However, Mr. Rutten shares Mr. Barnes' concerns about the risks of the project; he pointed out that Inmet, a C$3-billion company, is trying to build a project that costs close to C$4-billion. He also said that Petaquilla needs strong copper prices to be economic. But he wrote that the financi

A vote could come as early as this week in the U.S. Senate on a bill introduced by Senate Tax Committee Chairman Max Baucus (D-MT) and Senate Majority Leader Harry Reid (D-NV) containing a one-year renewable energy production tax credit (PTC) extension and a small wind turbine investment tax credit. The Senate bill, S. 3335, contains a one-year PTC extension at its current value. After December 31, 2009, any further extension would include the "presumption" of a cost cap, which would, through a complex formula, put a ceiling on the value of the credits of no greater than 35% of project value. The small wind ITC has a cap of US $4,000 per system.The 10-year cost for the PTC, including all technologies to which it applies, is projected to be approximately US $7 billion, while the ITC, which includes solar, would cost approximately US $907 million over 10 years. The bill also includes provisions to extend through 2014 the tax credits for solar energy, fuel cell and microturbine property, as well as the residential energy efficient property tax credit. Marine renewable energies could also benefit from the bill as credits to build wave, tidal, current and ocean thermal energy conversion systems of at least 150 kilowatts (kW) are extended through the end of 2011.

"Chinese commodity prices collapsed on the first day of trading after the Lunar New Year break as investors returned to markets gripped by fear over the impact the coronavirus will have on demand in the world's biggest consumer of raw materials. The country's three major commodity exchanges were hit by a fevered bout of selling as they reopened with Chinese traders getting their first opportunity to catch up with losses inflicted on overseas markets while they had been on holiday."

The full impact on copper is not known yet. We will have to wait and see how the health issue impacts manufacturing and also wait to see the China government fiscal response. Seemingly anything else at this time is speculation.

Time will tell and media does overhype. What I found noteworthy that these stories were linked to Dr Copper, which rarely happens. Agreed that we do not need to stir the hive, but I alerted Joe that he may receive lots of interest for the January edition of his index.

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
