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

It looks ordinary, like a razor-thin metal ribbon. But the high-temperature superconductor power transmission cable the Long Island Power Authority recently installed in Ronkonkoma revolutionizes how electricity is delivered, utility and federal officials said. The cable -- which is a fraction of the size of a traditional copper wire but can carry three times the power -- made its ceremonial debut yesterday with officials from LIPA, the U.S. Department of Energy and officials from the company that makes the cable. It went online April 22, the world's first use of the new technology in a commercial power grid. Utilities around the world are looking at superconductivity to improve efficiency of their grids and make them less vulnerable to blackouts. LIPA has buried three 2,000-foot wires in its right-of-way, and it will be installing a second generation of the wire in the same area as a test. "We view superconductor power cables as an important option that will help us further enhance the reliability of our grid as we meet our customers' increasing demands for electric power," LIPA chief executive Kevin Law said. He said the new cable allows the utility to increase capacity where its system has bottlenecks while increasing reliability and longevity and lowering costs. The wire, manufactured by American Superconductor Corp., conducts 150 times the electricity of the same sized copper wires, strand-for-strand. This means transmission cables can be far smaller and still conduct as much as three to five times more power in a smaller right-of-way.

A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

Investors piled out of Russian stocks Friday after the abrupt departure from the country of a foreign oil boss and the prime minister's unexpected severe criticism of a large steel firm. MICEX, the exchange where the bulk of trading in Russian stocks takes place, plunged by 4.8 percent as of 12:20 p.m. Russian time, while the RTS, a top stock index, lost 4.4 percent to drop beneath the critical 2000-point barrier for the first time since March. After Prime Minister Vladimir Putin's scathing attack on Mechel late Thursday, heavy trading in New York sent the steel and coal maker's stock down by nearly 40 percent, losses mirrored Friday morning in Russian trading. The premier criticized the company, which is the largest supplier of coal for steelmakers in Russia, for charging much higher prices for raw materials domestically than it does for its exports, and called for an antitrust investigation into its activities.

Due to a major contraction in orders intake, Wieland-Werke announced that it will introduce short-time working for 3,450 staff. Earlier plans of the company considered short-time working for 1,100 out of its 4,300 employees in Germany. The decision is attributed to very weak demand across all regions and industries, especially the automobile, electronics and construction sectors. As a result, impacted staff will work 20% less than normal.

Bill Baldwin -- Baldwin Anthony -- Analyst When we see the price of aluminum in relation the price of copper become more favorable for aluminum, does that show up in your demand for aluminum fairly quickly or not at all or over a period of time? Daniel Jones -- Chairman, President and Chief Executive Officer Well that's been debated over time. We prefer Encore Wire consistently and will continually prefer to ship and sell copper. That's just the way it is. The aluminum piece of that that you're referring to is a substitution depending on the relationship between the cost of each. Normally if aluminum is more expensive so is copper and vice versa. When copper gets to a certain dollar amount, there's no question that in the conversation the substitution question comes up. There are other costs involved with that most of the time. It's not a new scenario, but it doesn't necessarily increase the demand for aluminum beyond what the increase in the demand of copper would be. But it does enter into the conversation in the quote stage pretty early on when copper gets really expensive about what would it take to substitute aluminum for this piece of copper. And so in that, it's definitely in the conversation.

"One of the highlights at the booth will be the Cooled Charging Cable - the new technology which is an ideal fit for high-power charging stations. The Cooled Cable can multiply power-throughput of a charging cable and reduce charging times to below 20 minutes, making rapid charge times for all electric cars possible. This innovation puts super-fast charging within reach - even with big battery packs of new electric vehicles and trucks. The cables are thin, simple and easy to handle, bend-protected and have ideal grip position."

Monday, 28 July 2008 \nGuangdong Chigo Air Conditioner, a large-sized modern enterprise integrating the development, production and sales of household and commercial air conditioners, recently announced its agent in Egypt successfully won the contract for the Huawei correspondence station in Egypt after seven hardworking months.\n\n Huawei is said to have already achieved 12.56 billion dollars sales revenue, becoming one of the top five global telecommunications equipment producer, now with primacy globally, especially in Africa. Contracts for the correspondence station of Huawei in Egypt were mainly in the hands of Carrier for a long time, which means other brands could not compete with it and usually did not pass the test phase. Because the equipment for each station was valued at over 300 thousand yuan, the AC units could not run for a long time without a reliable capability guarantee. Right now the first set of Chigo splits is already installed in the station.\n\nThe vice president of Chigo Overseas Marketing Department , Mr. Peter Liao, said :"The success of this project means a lot for us. The intergrated ability of Chigo is already at new stage, being the supplier of a globally famous communication company. The cooperation with Huawei is meaningful for Chigo's development in the North African and African markets." For the success of the Huawei project, Huawei's subsidiaries in Libya and Sudan have also started to cooperate with Chigo, reveals the company's press release. \n\n\n

Mention copper to almost anyone in the PCB industry these days and the first thing that springs to mind is the ongoing price increase. Although copper pricing is not directly monitored by BPA, the impact on the price of laminate and PCBs is monitored through BPA's quarterly survey for its PCB Information Service. \n\nIn the short term, forecasted increases on the demand side for copper prices are likely to remain at least at the current level. The trend in copper usage has diverged in the fact that a number of different applications now exist. \n\nAt one time, 1 ounce (35µm) copper was standard, but the average is now 0.5 ounces. Using thinner copper, if the design will allow, can, to some extent, offset a price increase. However, one segment of the PCB industry which is particularly vulnerable to copper prices is the automotive sector, where recent developments have seen the introduction of thick copper PCBs for smart fuse boxes and power electronics. These boards use 4 ounce, 6 ounce and 10 ounce copper--up to 20 times the standard thickness.

The world's first commercial-scale tidal power turbine has delivered electricity into the British grid for the first time in preparation for full-scale operation, Marine Current Turbines announced yesterday. "SeaGen is the world's first commercial-scale tidal stream generating system by a large margin. It is more than four times as powerful as the world's second most powerful tidal current system, which is our own 300kW SeaFlow, installed off Lynmouth on the north Devon coast more than five years ago." Secretary of State for Energy, John Hutton said: "This kind of world first technology and innovation is key to helping the UK reduce its dependency on fossil fuels and secure its future energy supplies" Marine Current Turbines' next project, announced in February 2008, is a joint initiative with npower renewables to take forward a 10.5MW project using several SeaGen devices off the coast of Anglesey, north Wales. It is hoped the tidal farm will be commissioned in 2011 or 2012. The company is also investigating the potential for tidal energy schemes in other parts of the UK, and in North America.

These are heady times for the thin-film solar industry. The sector's dominant player, First Solar, has been on a tear of late, recently announcing it would build a second 10 megawatt power plant in Nevada, while Miasole, once thought to be ailing, has staged an impressive comeback, raking in an eye-popping $220 million. Nanosolar has developed a new ultra-fast solar cell printer, and even giants like IBM and Applied Materials have gotten in on the game. In the face of such intense competition, how will HelioVolt, a well-funded outpost of CIGS manufacturing in Texas, fare? The company hopes a new hybrid, super fast CIGS process it has developed in collaboration with the National Renewable Energy Laboratory (NREL), which combines its patented FASST process and NREL's non-vacuum deposition technique, will help even the odds. The Austin, Texas-based company licensed NREL's non-vacuum deposition process, which allows for the quick application of liquid precursors onto a printing plate and substrate, to manufacture its solar cells with a 12.2 percent conversion efficiency at a fraction of the regular cost and in record time - under 6 minutes. Another advantage is that the substrate can be made from a variety of building materials, including glass, metals, plastics and roofing materials.

As designed, the cities will have a total of four times the geographic area of Hong Kong, three times the population of Dubai, and - so the Saudis claim - an economic output equal to Singapore's. The coastal King Abdullah Economy City is designed to house two million in an area twice the size of Hong Kong. Entirely funded by domestic and foreign private investors, this is the only one of the four planned cities that is currently under construction. Aside from the seaport and residential area, KAC will also house a sprawling industrial zone, a central business district, a sea resort, and a multi-university education campus.

Nano-graphene platelets (NGPs) have high Young's modulus, high thermal conductivity (five times that of copper), electrical conductivity similar to copper, and are said to be 50 times stronger than steel.\n

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.

IEA's dire warning on green stimulus and renewables Kate Mackenzie, Financial Times The IEA's report for G8 energy ministers, to be presented this Sunday in Rome, has generated a few stories. Some picked up on the oil supply squeeze that awaits the world due to massive cuts in production investment. I wrote yesterday that the IEA forecasts that, for the first time since World War II, world electricity consumption will decline in 2009. IEA chief economist Fatih Birol said he personally thought the electricity forecast was the most striking finding of the report. However he was also keen to highlight concern about green spending in the G20 stimulus packages: The agency will also tell ministers that its calculation of the stimulus spending required from G20 nations on renewable energy was inadequate and should rise by a factor of six if greenhouse gas emissions targets set by the United Nations were to be met...

The American Council for an Energy-Efficient Economy issued a report yesterday touting the role that semiconductor-based technologies have played in making the U.S. economy more efficient. At the same time, the International Energy Agency issued its own report calling on governments around the world to be more aggressive with efficiency standards for ICT and consumer electronics, which are expected to demand twice as much power by 2022 and three times as much by 2030 - creating a need for another 280 gigawatts of power generation (i.e. like adding another Japan to the world, or more than 230 nuclear reactors). "This will jeopardize efforts to increase energy security and reduce the emission of greenhouse gases," according to an IEA news brief.

The Copper and Brass Servicenter Association reported that shipments of brass mill products amounted to 20.24Mlbs in May 2011, up by 0.4% on the previous month and down 11.3% y-o-y. This comes after a 13% fall in April from 25Mlbs in March, which was the peak that service centers experienced in Q1. Industry sources attributed the flattening in shipment levels in May to a decline in general consumer activity, also indicated by the Institute for Supply Management's manufacturing index falling from 60.4 to 53.5. In addition, it was reported that US brass mills are expecting lead times to narrow or flatten during Q3. Lead times are currently two to five weeks, having previously lengthened in early Q2. Lead times tend to be longer when consumer and service center demand is weak.
