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

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."

The redeveloped World Trade Center will be "one of the largest fuel cell installations in the world" according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. "Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson's leadership to combat greenhouse gas emissions and diversify the state's energy mix. To date, we've installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor's ambitious goals for significant increases in the state's renewable power," says Roger B Kelley, NYPA President and Chief Executive Officer.

Energy-efficient machine tools help to reduce operating costs for users and increase productivity. Investments in new machinery and equipment must make financial sense for the future. At the same time, it must be possible to operate machines efficiently and adapt them flexibly to meet new product requirements. This is what users are looking for in new machines. A central component of efficient machine operation is end-to-end management of energy requirements and usage.

According to a February survey from the Shanghai Metals Market, the operating rate at 21 major Chinese electrical wire and cable makers fell to 48.5%, a 21 percentage point fall from January. The drop in utilisation rate was the result of the Chinese New Year celebrations which fell in February this year. Operating rates are expected to rebound in March as cable makers increase production to fill contracts from China's State Grid Corporation. The survey also revealed that raw materials stocks rose by 15.3 percentage points in February to 49.8% of production in February.

International Wire Group, the US-based fabricator of copper wire, announced on 22nd March that its full-year operating income for 2012 increased by the 6.9% y-o-y to US$57.5M, a record level. The company said that its total pound-for-pound of wires sold, which are primarily copper and copper alloy wires, increased by 5.3% y-o-y in 2012. The company said "our strong full year operating results were driven by increased customer demand in our bare wire business, primarily from the automotive/specialty vehicles market." International Wire Group also announced fourth quarter results, with operating income increasing by 9.6% y-o-y, whilst its pound-for-pound of wires sold decreased by 3.6% compared to the fourth quarter of 2011. This was because a higher proportion of the group's business came from tolling contracts in the fourth quarter - whereby end-users provide the refined copper to be converted into wire.

"Through the development of the round one and two wind farms it has become apparent that a disproportionate amount of risk lies within the installation and burial of the power cables. This project will look at the methods and equipment used during the design and specification of installation requirements for export and array cable systems in the offshore wind industry. It aims to reduce risks to the cables during installation and operation, and reduce costs for installation and operation and maintenance activities."

"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."

"Centuries ago, Nikola Tesla envisioned and pioneered the concept of wirelessly transmitting power over long distances through the Earth's ionosphere. In the recent past, wireless energy transfer has occurred by way of an electromagnetic (EM) field set to a certain frequency level. While transmission efficiency over longer distances is attained to an extent by this method, it becomes increasingly difficult when complicated pointing and tracking mechanisms are mandatory to maintain the right wavelength between the transmitter and the receiver. Another drawback to this approach is that any object that falls between the transmitter and the receiver impedes the beam, thus interrupting power transmission to a potentially harmful degree if the power level goes beyond a certain threshold point. Even though microwave frequencies could prove effective to transmit power over long distances through a radiated EM field, the aforementioned caveats still apply. The other possible way to wirelessly transmit power is by non-radiative fields. For instance, a transformer operates by magnetic induction drawing similarities to wireless power transfer. Energy transfer in a transformer happens from the primary coil to a secondary coil in the absence of a direct electrical connection. The same approach can be seen in inductive chargers found in electric toothbrushes, for example. However, for this functionality to operate smoothly, primary and secondary coils must be positioned in close proximity to one another."

NEC Electronics America Inc. introduced to the Americas twenty-two new 16-bit All Flash microcontrollers (MCUs) for compact, low-power, battery-operated, and sensor-enabled systems. Based on NEC Electronics' high-performance 16-bit 78K0R CPU core, the new 78K0R/Kx3-L MCUs offer very low power consumption to extend battery life, and more on-chip integration to help reduce the size and cost of battery-driven and sensor-enabled systems, such as fire and security alarms, meters, industrial sensors, anti-shake digital cameras, handheld medical diagnostics devices, and data-logging and point-of-sale terminals. In addition to low power consumption, the new lineup offers high-performance on-chip oscillators, built-in circuits for sensor functions, and extended system operating time. "As environmental awareness has grown, energy-saving systems have become particularly reliant on MCU technology," said Jim Trent, Vice President, Multipurpose Microcontroller and Automotive Group, NEC Electronics America. "Over the past several years, NEC Electronics has delivered many ultra-low-power 8- and 32-bit MCUs that have met the demand for energy efficiency. With the introduction of the new 78K0R/Kx3-L devices, however, NEC Electronics is now delivering the benefits of energy efficiency in its 16-bit products."

The Yukon Environmental and Socio-Economic Assessment Board (YESAB) has recommended that the controversial Carmacks copper mine project can go ahead, providing that the Western Copper Corporation (TSX: WRN) complies with 148 conditions to mitigate potential adverse impacts. The tiny community of Carmacks with a year-round population of 500 is still considered an important service center for mining and for transportation, a century after it was a popular rest stop for the Yukon gold rush. However, members of the Little Salmon Carmacks First Nation want Western Copper to negotiate a better environmental engineering solution as part of an Impacts Benefits Agreement with the community. Located 38km northwest of the Village of Carmacks and 192 km north of Whitehorse in the Yukon Territory, the Carmacks copper project is planned to be an open-pit operation that will yield about 14,000 tonnes of copper cathode annually. Western Copper has targeted production to begin during the fourth quarter of 2010. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. Among the comments and concerns raised with the YESAB were routing of mining-related traffic, the heap leach detoxification process, sludge management, heap leach liner performance, and the estimates of closure costs. The YESAB Executive Committee said it was satisfied that: Western Copper adequately consulted with the First Nations in whose territory, and the residents of any community in which the project will be located or might have significant or socio-economic effects; The project proponent provided sufficient information in the project proposal to allow for the assessment of potentially significant effects; Significant adverse environmental or socio-economic project and cumulative effects identified within the scope of the scre

Sony Corp will invest $369 million (40 billion yen) to power up its lithium-ion battery production operations, adding new facilities and augmenting existing lines. The infusion, which Sony said is the first phase of investment in lithium-ion batteries the company is undertaking as part of efforts to reinforce core areas of its component and semiconductor business over the next three years, will be used to construct new production facilities and to enhance existing lines at Sony's lithium-ion battery production sites in Japan, the Motomiya Technology Center and Tochigi Technology Center of Sony Energy Device Corp. Sony said it is making the investment in response to the growing demand for lithium-ion batteries and that the new production facilities will focus on electrodes, battery cell production lines, and charge and discharge equipment, among other technologies. Sony further reminded its expanding lithium-ion battery production in Singapore and China, and said that in total its monthly production capacity will increase from the current level of 41 million cells per month to 74 million cells in 2010. Sony's $369 million investment will start in its current fiscal year and continue through the second half of its fiscal year 2010. Sony's fiscal Q1 2008 concluded in June. Meanwhile, Matsushita Electric Industrial Co recently committed $923 million (100 billion yen) to build a plant in Osaka, Japan, that is expected to bring its cell production to about 75 million a month from its current 25 million cells per month. Sanyo Electric Co has also reportedly announced plans to invest, promising $1.15 billion (125 billion yen) to develop its rechargeable-batteries business over the next three years. That investment is expected to increase cell output to 90 million per month from Sanyo's current 70 million cells per month. All three of the Japan-based companies last year suffered from loses brought on by their battery operations. Sony-made lithium-

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.

General Cable Corporation has announced its sales results for Q4 2008. In volume terms, sales in Q4 2008 contracted by 6.3% y-o-y. In the same period, operating income decreased by 17.8% y-o-y to US$76.4 million. The company attributed the decline in its operating income to weak demand in developed economies and lower capacity utilisation. Sales to Europe and North Africa contracted by 7.8% y-o-y, particularly due to lower demand and pricing for construction products in Spain, and weakening activity across Europe. In North America sales fell by 6.6% y-o-y, as the company experienced reduced demand for high metal content copper telecommunication and low voltage cables.

Luvata, a copper semis fabricator, believes that even though destocking in the copper supply chain is over, a significant rise in demand is not anticipated until mid-2010. The company expects that Asia will be the first region to recover, followed by North America and Europe. As a result of destocking, Luvata has got used to operating at a lower level of stock, and therefore became more efficient in its production procedures. The company intends to keep operating at lower stock levels even in periods of growth. While demand before the summer showed some recovery signs, the company is now waiting for the autumn to see whether the positive trend will continue.

Ohio-based supplier of specialty copper alloy products Brush Engineered Materials Inc. reported second quarter results. Q2 2009 sales were US$174.1 million, 29% lower than the same period a year ago but an improvement of 29% from the first quarter this year. Net loss was US$0.8 million versus net income of US$7.2 million in Q2 2008. The Specialty Engineered Alloys segment reported Q2 sales of US$41.2 million, compared to sales of US$83.0 million the same period in 2008. Operating loss for Q2 was US$9.3 million compared to an operating profit of US$4.8 million a year ago. The decline in segment sales was primarily due to the effect of the severe global recession in key markets including telecommunications, computer, automotive electronics, oil and gas, aerospace and heavy equipment. A portion of the decline was due to lower metal prices. The company is foreseeing an improving order book and is expecting to generate a slight profit in Q3 this year with higher sales volume and positive impact from its cost-reduction activities.

International Wire Group announced results for the second quarter ended 30 June 2009. Net sales for the quarter were US$102.0 million, compared to US$199.9 million for the same period in 2008. The decline was due to a lower copper price and decreased volume. Operating income for the second quarter was US$1.3 million compared to US$10.9 million. The lower income was attributed to lower sales volume in all business segments but was partially offset by operating cost reductions and lower selling and administrative expenses. Net loss was US$0.9 million, compared to net income of US$5.6 million.

According to a survey conducted by Antaike in China, 33 semis fabricators out of 55 had not started operations in the first week after the Spring Festival. It was reported that these companies will resume operations after the 10th day of the Chinese New Year. The majority of the companies that had started operations by the first week of the Chinese New Year did not maintain any raw material inventory as procurement aimed to meet only current production needs.
