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

Aurubis has announced that it will reduce its production capacity of flat rolled copper products by 35,000t in a restructuring process that will take place beginning from H2 2013. The group intends to transfer some of its rolling operations from Finspång, Sweden to Zutphen in the Netherlands and is also considering moving other types of production currently located at the Finspång factory to its facility in Buffalo, USA. Aurubis attributed the consolidation to structural overcapacity in the flat rolled products market and made specific mention to declining demand in the engine cooling segment.

""Our goal is to build rocket engine parts up to 10 times faster and reduce cost by more than 50 percent," said Marshall propulsion engineer and project leader Chris Protz. "We are not trying to just make and test one part. We are developing a repeatable process that industry can adopt to manufacture engine parts with advanced designs. The ultimate goal is to make building rocket engines more affordable for everyone.""

"The composite can be applied by spraying or other commonly used wet chemistry processes and cures at 150-200°C. It is suitable for steels, metal alloys and metals such as aluminum, magnesium and copper, and can be used to coat any shape of plates, pipes, gear wheels, tools or machine parts."

"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."

Amid a prolonged economic slump, demand for nonferrous metals and processed products of them is staying below the previous year's level but the consumption of raw materials including scrap is up

"Artist Alice Anderson has chosen copper wire as her material of choice and has proceeded to use it to wrap several objects - including a telescope, a flatscreen TV and even a set of stairs. The process is delicately handled so even details like the knobs on an electric guitar are visible through the copper thread."

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 solar industry and semiconductor industry are intimately connected. Both industries rely on silicon and both use much of the same processing technology and supply chain to produce their products. Nowhere has this connection been on better display than last week at the Moscone Center in San Francisco California, where the Intersolar North America made its debut in conjunction with SEMICON West 2008. The show provided an opportunity for those in the two industries to connect and allowed those companies that work in both spaces to showcase their collective efforts. According to Chris O'Brien, Head of Market Development and Government Relations for North America for Oerlikon Solar, holding the two conferences together gave companies greater exposure and showed the promise of the U.S. solar market. In recent months a number of traditional semiconductor companies including Intel and National Semiconductor have made announcements that they are making plans to enter the solar industry in one way or another. Intel spun off it's solar research area into a new solar company called SpectraWatt. National Semiconductor announced that it will be introducing it's first solar product, SolarMagic, that could raise the efficiency of residential and industrial solar systems. Kevin Kayser, Senior Marketing Manager at National said that he product will be targeted at installers and integrators and much planning went into the company's decision to enter the solar space. "Photovoltaics currently has less than 1% of the energy market, but we think it has potentially one of the fastest growth rates of any alternative energy source. Now certainly we're looking at wind, we're looking geothermal, we're looking at other sources, but from an electronics point of view we saw that we had the most immediate potential impact in solar photovoltaics," Kayser said.

ArcelorMittal (NYSE: MT), a steel manufacturer based in New Deli, launched a clean technology venture capital fund to support ventures that have relevance for the carbon-intensive steel industry. The Fund has made its first investment of US$20 million in Miasolé, a California-based pioneer in the development of thin-film solar panels Miasolé has developed unique high volume manufacturing processes that enable efficient production of Copper Indium Gallium Selenium (CIGS) solar products on a flexible stainless steel substrate. This technology promises to dramatically lowers the installed cost of Photovoltaic (PV) systems and will enable renewable energy from the sun to replace carbon generating fossil fuels. Fund managers will be working with leading venture capital firms, including Bessemer Venture Partners, Khosla Ventures, and Kleiner Perkins Caufield & Byers, to identify worthy cleantech ventures. ArcelorMittal also announced that it has created a new carbon fund in order to strategically engage in the carbon market and promote climate friendly solutions that are relevant for the steel industry. The fund, which has an initial investment commitment of €100 million (US$ 157 million) is currently looking at investment opportunities in renewable energy, energy efficiency, methane capture and greenhouse gas reducing technologies--all of which have the potential to generate carbon credits under the Kyoto Protocol. ArcelorMittal intends to use the carbon credits received from these Clean Development Mechanism and Joint Implementation projects for compliance in the EU Emissions Trading Scheme.

CAMBRIDGE, Massachusetts (Reuters) - A U.S. scientist has developed a new way of powering fuel cells that could make it practical for home owners to store solar energy and produce electricity to run lights and appliances at night. A new catalyst produces the oxygen and hydrogen that fuel cells use to generate electricity, while using far less energy than current methods. With this catalyst, users could rely on electricity produced by photovoltaic solar cells to power the process that produces the fuel, said the Massachusetts Institute of Technology professor who developed the new material.

Driven by the need for increased speed, portability and wiring density, the interconnect pitch on semiconductor packages, and the corresponding high density interconnect (HDI) substrates, continue to shrink. The combination of filled blind microvias and build-up technology provides a means to achieve the required wiring densities. With the rapid growth of this technology, the use of electrodeposited copper for filling blind microvias has become a widely adopted process for manufacture of both HDI printed circuit boards (PCBs) and also semiconductor package substrates.

BHP Billiton is disappointed by today's High Court decision on the definition of 'production process'

The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province in central New South Wales. A gold and copper mine, it is 100% owned by Australia's Newcrest Mining, and is one of three operations owned by the company in the province. The others are Cadia East and Cadia Hill, the largest of the three. "The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province."Ridgeway is in the process of transitioning from the sub-level cave to a block cave beneath the existing mine. In 2007 the Newcrest board approved development of the Ridgeway Deeps block cave. It will be the first natural caving operation to be developed by Newcrest and will be the deepest block cave in Australia. The company says it is spending A$525m to develop it. The mineral resource at Ridgeway Deeps was re-estimated following a geological reinterpretation which yielded an increased resource of 20 million tons containing 0.5 million ounces of gold, and 0.05 million tons of copper.

Sark Wire Corporation, a wholly-owned subsidiary of Turkish based Sarkuysan, is to open a copper wire processing facility in Albany with investment of US$10m. The new facility will have capacity to process 30m lbs of copper per annum and is due to be fully operational in 2009, creating 30 new jobs.

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.

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
