"The IEA estimates that of all efforts required to deliver a 50% reduction in global emissions by 2050 24% will need to come from end use fuel efficiency, 12% has to come from end use electricity efficiency and a further 7% will need to come from power generation efficiency. There is substantial potential for improving thermal efficiency of Europe's power plants. Our coal plants operate at an average 38% (BAT - Best Available Technology - on new coal plants delivers 46%). Our gas plants operate at an average of 52% efficiency (BAT- Best Available Technology - on new gas plants delivers more than 60%). Due to the age of the installed base, the average efficiency of Chinese coal plants is now higher than in Europe."

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

"If successful, Northeastern's meteorite-inspired magnets would contains no rare earth minerals and could help power a renewable power generator or an EV motor better than today's best commercial magnets. "

Underscoring the degree of innovation occurring in semiconductor packaging, four of the eight finalists in the SEMI Best of West awards were new packaging technologies - three of these serve in 3-D IC applications.

A new approach to storing electrical energy can store more energy than gasoline in the same volume, and could help extend the range of electric vehicles. But some experts say other approaches are more practical. The biggest technological hurdle facing electric vehicles is their range. Even the best rechargeable batteries cannot match the density of energy stored in a fuel tank. Combining electric power with a combustion engine to make a hybrid electric vehicle sidesteps that problem. But a new take on electrical power storage that is part battery, part chemical fuel cell could ditch gasoline for good.The new design stores energy more densely than petrol, and was conceived by Stuart Licht of the University of Massachusetts, Boston, and colleagues. Batteries produce electricity from a closed chemical system that is eventually exhausted. Fuel cells use a constant supply of fuel, so they are continually topped up. Licht's cell has features of each. Its negative electrode, or anode, is made from vanadium boride, which serves double-duty as a fuel too. But unlike the flowing fuel of a fuel cell, the material is held internally, like the anode material of a battery. The vanadium boride reacts with a constant stream of oxygen, as in a fuel cell, provided by the positive electrode, or cathode. This brings in a supply of air from outside.

RUEIL-MALMAISON, FRANCE, August 15, 2008. Schneider Electric has signed a CAD 498 million definitive arrangement agreement with Xantrex Technology Inc for the acquisition of all common shares of Xantrex. Xantrex is said to be a top three global player in the solar and wind inverter market with strong growth potential. It also has a leadership position in the North America. Awaiting approval from Xantrex shareholders, the deal is expected to be closed by October 2008. Schneider Electric says it expects to realise significant synergies in acquiring Xantrex, leveraging the strengths of both companies. Xantrex provides experience in advanced power electronic technology for renewable energy, and dedicated solar and wind channel access. Schneider Electric boasts a wide international footprint with solution centres and leverage with APC in purchasing, technology and operations. Xantrex Chairman Mosaadiq Umedaly comments: "We think it is the best way to develop our business, taking advantage of our leading technology, products, market knowledge, and distribution channels together with Schneider Electric's global sales, service, supply chain, and solutions capabilities."

Hewlett-Packard said on Monday it plans to buy Colubris Networks, furthering the consolidation of wireless networking companies. Financial terms were not disclosed. HP said the deal should close by the end of fiscal 2008, which occurs in October. Colubris, founded in 2000 and based in Waltham, Massachusetts, sells wireless access infrastructure products based around the 802.11n wireless standard, which can match or best the speeds of a plugged-in broadband connection. But the upgrade to 802.11n poses many issues for it to work efficiently. Colubris has centered many of its products around the predicted upgrade of those networks over the next few years. Colubris also sells wireless security and network management products. HP said products from Colubris will be incorporated into its ProCurve Networking portfolio, which will improve HP's ability to serve the health-care, transportation, manufacturing and education markets, among others. In June, Belden said it would buy WLAN vendor Trapeze Networks for US$133 million

Murchison has sold its 9.2% stake in Midwest Corp to Sinosteel for $107 million following Sinosteel's takeover of Midwest. Posted: Thursday , 11 Sep 2008 SYDNEY (Reuters) - Australian iron ore prospector Murchison Metals Ltd has sold its 9.2 percent stake in fellow Australian firm Midwest Corp to China's Sinosteel for about A$135 million ($107 million). The move follows Sinosteel's $1.3 billion takeover of Midwest earlier this year, which defeated a plan by Murchison to merge with Midwest. The two Australian firms are neighbours in the as-yet undeveloped Yilgarn iron ore mining region of west Australia. Murchison said in a statement on Thursday the sale of the Midwest shares is in the best interests of the company, especially given significant changes in world financial markets over the past three months. "The cash raised through the sale gives Murchison greater flexibility in relation to both developing existing projects and in pursuing fresh opportunities," Murchison Executive Chairman Paul Kopejtka said in the statement.

"There's nothing going on. People have stopped buying and it doesn't look any better for the first part of next year either," said a physical trader. "People don't want to carry too much stock over the year-end but they don't have a lot of choice because of the turndown in demand. If people have got metal the best thing they can do is dump it on warrant and get paid by the warehouses," he said.
