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

Aluminum may have been responding to two different events in the week ending July 11 when it hit a succession of all-time price highs , but the market remains divided over the medium-term direction, given that world fundamentals point to weak demand and rising stock levels. \n\nFundamentally, however, analysts and market players were mixed in their impressions of whether the price could be sustained, especially as word emerged from China that the cuts may not be a certainty. \n\nAluminum finished floor trade for the week at $3,318/mt, up $150 from the July 4 closing price of $3,168. Fundamentally, however, analysts and market players were mixed in their impressions of whether the price could be sustained, especially as word emerged from China that the cuts may not be a certainty. \n\nPointed out a US broker, "When you hear producers [in China] are shutting production because demand is weak, that's normally bearish," yet the market saw "insane" price moves. "I hear metal just continues to pour into warehouses, and not all of it reported, obviously, [since] otherwise you'd see it in the stock numbers. A lot is going off warrant," he pointed out. \n\n\n

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

Five of the major Japanese electric wire makers, (Furukawa Electric, Hitachi Cable, Fujikura, SWCC Showa Holdings, Mitsubishi Cable Industries Ltd.) have all posted consolidated recurring losses in their business results for FY2008 ended March 2009. All except Sumitomo Electric Industries, which reported lower sales, posted losses due to the dramatic fall in copper price during H2 2008 as well as the downturn in the automotive industry. Their copper inventory valuation losses have reduced their profits significantly. Sluggish demand is reported across a range of automobile related products including copper strip for connectors, winding wire and wiring harness.

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

The European Union (EU) adopted a directive in late October that will place a cap on greenhouse gas emissions from all flights arriving at or departing from EU airports, starting in 2012.

Could this cap underpin a drive toward lightweighting in aviation?

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."

"Any organisation may claim to have developed a standard, but ISO warns that 'not all standards are created equal.' ISO is publishing a new brochure that clarifies the distinctions between international standards of the type developed by the ISO system, using well described and accepted principles and disciplines, and 'private' standards developed by industry consortia and other groupings."

Prysmian declared the offer it advanced for Draka Holding on January 5, 2011 unconditional. The offer concerns all Draka shares in circulation, valuing them at EUR 8.60 apiece in cash plus 0.6595 ordinary Prysmian share. All offer conditions, except for the condition for granting all necessary authorisations, have been fulfilled, Prysmian said, adding it was waiving the regulatory condition. Prysmian will start a post-tender offer, which will run until 22 February, for the remaining minority shares in the Dutch company, at a price of EUR17.20 (USD23.43) per share in cash and stock. Including the preference shares to be acquired from Draka's minority shareholders ASR Levensverzekering and Kempen, Prysmian's holding will reach 91.4% in total, the buyer added. Upon a successful acquisition, Draka shares will cease trading on the Amsterdam stock market.

"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)."

"But if nature was forced to use the pipes-and-ion-channels approach, that leaves us with plenty of scope for speeding things up using silicon and copper (and this is quite apart from all the other more exotic computing substrates that are now on the horizon). If we were simply to make a transition membrane depolarization waves to silicon and copper, and if this produced a 1,000x speedup (a conservative estimate, given the intrinsic difference between the two forms of signalling), this would be an explosion worthy of the name."

"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."
