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

Rohm and Haas Company has reported second quarter 2008 sales of $2,567 million, a 17% increase over the same period in 2007, with Electronic Materials and the chemical businesses outside North America delivering strong growth. The Electronic Materials Group comprises two reportable segments which provide materials for use in applications such as telecommunications, consumer electronics and household appliances. Sales for the Electronic Materials Group were $536 million in the second quarter of 2008, up 34% over the same period in 2007, reflecting the impact of acquisitions in Display Technologies as well as solid organic growth of Electronic Technologies. The Electronic Technologies segment is comprised of the company's Semiconductor Technologies, Circuit Board Technologies and Packaging and Finishing Technologies business units. Sales for the segment of $460 million were up 16% versus the second quarter of 2007, driven by strong growth in Asia for all business units. Sales in the second quarter excluding precious metals pass-through sales were up 15%. Semiconductor Technologies sales grew 13%, reflecting strong demand and favorable currencies, particularly in the Asia Pacific Region. Circuit Board Technologies sales increased 20% as compared to the same period last year, with solid growth in the Asia Pacific Region more than offsetting declines in North America. Packaging and Finishing Technologies sales rose 20% versus last year, primarily driven by strong growth in precious metal sales and in process sales. Adjusted pre-tax earnings for this segment of $107 million were up 11% from the second quarter of 2007, reflecting increased demand and favorable currencies, partially offset by higher metal costs and increased costs related to expansion efforts, including the new Asia Technical Center in Taiwan.\n\n\n

Growth in Asia is illustrated from this reporting at multiple levels of business - Opportunities are available for copper in a multitude of applications.

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

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

But the new technologies-which could help consumers cope with these prices-are unlikely to arrive in large numbers in time for the next oil spike. According to the authors of "The Impact of Plug-in Hybrids on U.S. Oil Use and Greenhouse Gas Emissions," a chapter in the new book Plug-in Electric Vehicles: What Role for Washington, published by the Brookings Institution, cars are durable goods that last well over a decade. "The transformation of the light-vehicle fleet to new internal combustion technologies or to hybrid and plug-in hybrid technologies will take decades from the time such vehicles are widely available at competitive prices," according to the authors, Alan Madian, Lisa Walsh and Kim Simpkins, researchers at consulting firm LECG. They believe it could take another decade from now until the new technologies compete on a price basis, and begin the process of replacing current fleets.

"Developed by Prysmian's R&D Headquarters in Italy, P-Laser technology is eco-sustainable. The HPTE insulating system of P-Laser cables uses thermoplastic materials unlike traditional XLPE cables with cross-linked polyethylene insulation. The metal used for the conductor and the outer cable screens under the protective sheath is also recyclable, making the cable 100% eco-friendly. From the efficiency point of view, P-Laser technology allows grid operators to work at temperatures above the typical 90°C as usual with XLPE traditional technology. This higher thermal performance allows them to increase the power transmission for the same conductor section, or a longer cable life at the same temperature, but above all it allows higher capability. This is particularly important in the event of emergencies, grid congestion and "N-1" conditions (disconnection because of malfunction or maintenance of an adjacent line)."

"The figures show that copper-based broadband technologies (DSL, ADSL, and ADSL2+) continue to be dominant, although fiber-optic broadband technologies (which include VDSL and VDSL2, according to the Broadband Forum) are taking a firmer grip with growth rates of 17.6% overall. Although DSL remains the predominant technology, fiber continues to outpace all access types in new deployments, according to the analysts."

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."

"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?"

HL Technology, a listed Chinese producer of wire and cables, announced on 20th November that it plans to sell its 55% stake in Tianjin Rituo Automotive Electronics to Wang Xiang, for RMB58.6M (US$9.3M), stating that the venture had not been as profitable as expected. The company also announced it is acquiring the entire equity in a separate company, Rituo High Technology, from Rituo Automotive Electronics for RMB15M (US$2.4M). Rituo High Technology researches, designs and manufactures wiring harness components such as the wires used for signal transmission. By purchasing Rituo High Technology, HL Technology said it hopes to develop its own wholly owned subsidiary in the wiring harness sector.

"Thermal energy storage (TES) is a system to store thermal energy. TES can be differentiated into three different categories, namely sensible, latent and thermochemical. The main drivers that propel development of TES system are advancements in material sciences and the emergence of smart thermal grid. Although some of the TES system is already mature especially sensible, adoption of this technology is still slow due to lack of awareness from stakeholders to employ this technology as a method to achieve energy efficiency. Furthermore, high cost of new technology and the recent dramatic drop in oil prices have inhibited or slowed the adoption of TES due to less compelling economics. By using Analytical Hierarchy Process (AHP), emerging TES systems based on latent and thermochemical have been identified as the future of TES systems because it shows remarkable performance capabilities. However, strengthening legislation and standardization frameworks need to be done to see wider adoption of TES systems in the future, especially in Europe and North America."

"The copper industry is already facing substitution challenges from materials like aluminium and needs to use technology to help ensure larger-scale, more permanent switches are not made, industry participants said. A group of panelists at the Metal Bulletin and American Metal Market Copper Seminar in New York on Wednesday June 6 said that while technology is clearly an opportunity for the industry, there are still some risks. According to Freeport McMoRan vp sales and marketing Steve Higgins, much of the "easy substitution" - such as plumbing tube or transformer lines - has already happened. "Substitution is less than 2% of refined demand today… It's a bit troubling, but it happens," he said. "The bigger worry is that aluminium is going to make inroads into products that have high switching costs - ACR tubing, motors, or into some medium to high voltage power cables and the like that the manufacturers have to go in and put in a lot of capital costs to convert. Once converted, switching back becomes "extraordinarily difficult," he said. "That's the biggest risk to our market as I..."

"Wireless charging manufacturers are expected to reach economies of scale to offer the technology at a competitive price by 2016 or 2017. The perceived value also may improve with time. The smartphone market is the earliest adopter of wireless power charging technology, and is the largest revenue contributor to the global market. Other potential applications include consumer electronics (e.g., tools, lights, phones, headsets, and laptops), electric vehicles, and industrial uses. Wireless charging technology is expected to expand into these markets during the forecast period."

Compared to other solar energy applications, solar cooling is a relatively new, but growing, technology. Many projects using the technology are still for the purposes of demonstration only, but a growing number of systems are being implemented all over the world for conventional use. In order to give an insight into this innovative technology, detailed information about the possible technical applications of solar cooling systems is provided in this section.\n\nPassive solar cooling, based on bioclimatic strategies such as sun protection using natural screening devices or increased cooling by using ponds or water basins o the roof or close to the external walls, is widely applied and should be the first step to take in cooling a building. Such measures are easier and less costly to implement, they decrease the need for additional cooling and, therefore, for additional energy demand (and also for investment). Sufficient insulation of the building also decreases the need for cooling, as well as for heating.\n\nIf the outcome of these measures is not sufficient in itself, a solar assisted cooling system may be an intelligent solution. In solar assisted cooling systems solar heat is used to drive the cooling process for air conditioning in buildings. Instead of using electricity, free solar thermal energy is used for cooling through a thermal-chemical sorption process.\n\n
