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

Chile's national copper company, CODELCO, announced Friday that it will invest US$1.5 billion in new environmental and health projects over the next five years. The company plans to utilize copper's antibacterial properties in projects involving Santiago's subway system (Metro) and the salmon-farming industry.

Air batteries, which create electricity from a reaction between oxygen in the air and a zinc negative electrode, can store five times as much electricity as a similarly sized li-ion battery, although there are problems before they can be commercialised

African Eagle Resources (AIM: AFE; AltX: AEA) today announced a 20% resource increase at its first copper project, Mkushi in Zambia, that will extend the life of the mine by two years. The project is the company's most advanced project and will generate first revenue for African Eagle over the next three to five years. Mark Parker, managing director of African Eagle, told Mineweb today the Mkushi project's feasibility study was scheduled to be completed by the fourth quarter of this year and the company plans to be in open pit production here by 2010. A full mining licence for the project has also been approved. The project's larger resource of 18.5mt at a grade of 0.83% copper has been upgraded to the indicated category which gives the company and investors greater confidence in it. The bigger resource has extended the life of the mine from six to about eight years, while its profitability level will still be further refined. Parker said the feasibility study has not produced any unwanted surprises at this stage and the company has covered any "unknown unknowns" around the project. Mkushi will produce about 30,000t of contained copper annually once the project is up and running.

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

The world's first commercial-scale tidal power turbine has delivered electricity into the British grid for the first time in preparation for full-scale operation, Marine Current Turbines announced yesterday. "SeaGen is the world's first commercial-scale tidal stream generating system by a large margin. It is more than four times as powerful as the world's second most powerful tidal current system, which is our own 300kW SeaFlow, installed off Lynmouth on the north Devon coast more than five years ago." Secretary of State for Energy, John Hutton said: "This kind of world first technology and innovation is key to helping the UK reduce its dependency on fossil fuels and secure its future energy supplies" Marine Current Turbines' next project, announced in February 2008, is a joint initiative with npower renewables to take forward a 10.5MW project using several SeaGen devices off the coast of Anglesey, north Wales. It is hoped the tidal farm will be commissioned in 2011 or 2012. The company is also investigating the potential for tidal energy schemes in other parts of the UK, and in North America.

Ireland's OpenHydro and Germany's RWE are spending millions to try to turn the power of waves into electricity With oil prices hitting almost daily record highs and global warming climbing up the public agenda, the need for alternative energy sources has never been more urgent. But while wind and solar have dominated the recent rush to invest in renewables, market watchers reckon it could now be marine energy's turn to shine. Ocean power-using the energy from waves or tidal flows to produce electricity-is quickly coming of age as a viable green resource that could help meet ambitious global targets to reduce greenhouse gases and dependency on fossil fuels. European and North American power companies such as Canada's Emera (EMA.TO) and Germany's RWE (RWEG.DE) are spending millions to fund wind and tidal projects. This investment has led to a new generation of more efficient technologies, with dozens of prototypes expected to be ready for commercial deployment within the next five years. "There's huge interest in both wave and tidal technology," says Thomas Boeckmann, clean tech analyst at market research firm StrategyEye in London. "It's gaining a lot of attention from energy companies, which will be able to offer financial backing and technical expertise to these startups."

HO CHI MINH: PetroVietnam is setting up a new company to manage its biofuel production and distribution, according to local media reports. The new company, PetroVietnam Biofuel Joint Stock Co. will have an initial capital of about US$2.7 million. PetroVietnam General Services Joint Stock Corp. (Petrosetco) will hold 51 per cent of the company. PetroVietnam Oil Corp. will hold 29 per cent, Binh Son Refining and Petrochemical Co. Ltd., 15 per cent, and PetroVietnam Finance Joint Stock Corp. (PVFC), five per cent. The new company will produce ethanol from cassava. The output will be blended with gasoline sold at the local petrol pumps to help reduce the country's fossil fuel dependence.

This new process for creating features on silicon wafers that are between five and 20 nanometers thick has been developed by a multidisciplinary team led by Craig Hawker, materials professor and director of the Materials Research Laboratory at UCSB and the members of his research group. Hawker worked with professors Glenn Fredrickson - and his research group - and Edward Kramer - and his research group.

While the prices of zinc, copper and other base metals are fixed at the end of frenetic five-minute sessions in the 'ring,' situated in the LME's centre, it is a sense of caution which is ultimately prevailing among traders.

The top five major uses of copper by market segments.

The Anglo-Dutch steel producer, which this week announced the elimination of 2,500 jobs at its UK plants, says the surge in British electricity prices from £24 a megawatt hour to £75 MWh over the past five years has been greater than "virtually anywhere else in Europe". If that is so, Britain's liberalised energy market is serving its users ill.

Nano-graphene platelets (NGPs) have high Young's modulus, high thermal conductivity (five times that of copper), electrical conductivity similar to copper, and are said to be 50 times stronger than steel.\n

The tipping point at which the world's cleanest, most renewable resource is cost-competitive with other sources of energy on electricity grids could happen within two to five years in some US regions and countries if the price of fossil fuels continues to rise at its current pace, they add.

The road to grid parity for PV power generation will be difficult, needing five or more years to compete with utility power, unsubsidized, on a large scale, noted Mark Thirsk, managing partner at Linx Consulting, at a recent SEMI PV forecast luncheon (Sept. 18) in Santa Clara, CA Most input materials for PV production are in relative oversupply and will not constrain production, Thirsk pointed out - and for this reason manufacturers are conservative about capacity investment. In particular, his PV module production forecast (see Fig. 1, above) shows an overstep in demand in 2008. One reason for suppliers' reluctance to build capacity for entering the silicon supply chain is that it is an inefficient process. "Only about 15% of all the silicon going into the supply chain goes into the wafers, so it's a pretty wasteful and capital intensive process, so there is a lot of reluctance to build capacity," said Thirsk. Despite the efficiency challenges, Thirsk's forecast indicates that an oversupply may occur in 2009 Because >40% of PV grade silicon is lost at the wafering step, Thirsk believes this represents a significant opportunity for the right technology. Additionally, diamond wire is a potential replacement for slurry technology, but this technology is still immature. In the crystalline silicon (c-Si) value chain, Thirsk sees opportunities for optimizing mono-crystalline wafers with metal wrap technology and backside contacts; process optimization and material improvements would improve cell efficiency, and glass, wafer, backsheet, and grid improvements can enable more efficient light capture. Looking ahead, Thirsk told the audience that while thin-film technologies will enjoy strong growth "and may be more attractive to value-add materials and equipment suppliers, thin-film cell production will remain a minority share for the medium term." (see Fig. 3, below) He closed his presentation encouraging the creation of a Moore's Law type of roadmap for the PV

In a December report, Gartner analyst Ken Dulaney predicted that by the end of 2011, 70% of all new worldwide voice and data client-to-LAN connections will be wireless. The firm also estimated that $100 billion will be wasted over the coming five years following outdated network design principles.

ontract workers at Chile's state copper company agreed to end a 20-day strike Monday that had idled production at three of its five mines, causing more than US$100 million (euro65 million) in losses.

And it still has a long way to go. Today, barely one in five people around the world has access to the internet. Yet around three-quarters of the world's population lives within reach of a mobile network. In the decade ahead, many people, especially in developing countries, will have their first contact with the internet via a mobile phone.

CHINA will not approve new aluminum plants or expansion projects for the next three years as part of a plan to revitalize the nonferrous metals industry. The government also aims to create three to five major nonferrous metals companies by 2011, with the top 10 domestic players controlling 90 percent of copper production, 70 percent of aluminum, 60 percent of lead and 60 percent of zinc in their respective markets, the State Council, China's Cabinet, said yesterday. A draft of the nonferrous sector rejuvenation plan was unveiled in February when it was approved.
