Fuel cell power for new World Trade Center - 0 views

  • 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.

Copper Trends in Data Center Cabling - 0 views

  • High-performance, low-cost passive copper cabling remains the preferred alternative for short-reach applications in the data center. However, standard round copper cables can be bulky and consume precious space. A recent innovation in manufacturing technology by 3M has resulted in the development of a uniquely shielded, thin, ribbon-style copper cable. The cable has the ability to fold multiple times and maintain signal integrity, allowing for higher-density racks and space savings. A major barrier to decreasing the size and stiffness of a round cable is inherent in the construction of traditional cable. This is an issue because a round copper cable can extend up to nine inches when routed behind a cabinet. In conventional, twin axial constructions, the shield is applied by wrapping it spirally around the insulated wire pair. This layer is then overwrapped to provide support and retain the primary shield wrap, increasing the stiffness of the pair. Multiple pairs are then cabled and an overall foil and braided shield are typically applied, thus further increasing the cable bulk and stiffness.

    Upgrades on Eve of Democratic National Convention's 'Greenest Political Convention in History' Held in Denver\n\nDENVER, CO--(Marketwire - August 22, 2008) - Data393, a Managed Data Holdings Company and a leading provider of colocation, managed hosting, disaster recovery and IP network services, announced today the completion of "Green" initiatives to decrease the facility's carbon footprint. The announcement was made in support of the City of Denver's role as host of the 2008 Democratic National Convention, which is touted as the "greenest political convention in history." Data393's Green initiative also follows in the footsteps of the City of Denver's efforts to leave an enduring legacy of sustainability programs in the Denver metro area. \n\nResulting from the expansion of its multi-million-dollar, 30,000-square-foot data center, Data393 has implemented technological advances and infrastructure upgrades at its Englewood data center, just south of Denver, that reduce its environmental impact. \n\n

Sony Invests $369M to Expand Lithium-Ion Battery Production - 0 views

  •  
    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-

US service centers see a softening of orders in March - 0 views

  •  
    According to data from the Copper and Brass Servicenter Association(CBSA), total shipments from US brass and copper mills slipped 1.1% y-o-y in 2012, to 261.5Mlb (118,600t). Data from November had indicated that year-to-date shipments were roughly unchanged from 2011, however, a 16.9% m-o-m drop in shipments in December tipped total shipments into contraction territory for the year. In general, copper semis shipments were stronger than alloy shipments, with copper rod shipments up 8.3% in 2012, to 64.4Mlb (29,200t). Total alloy shipments fell 5.4% in 2012, to 139.6Mlb (63,300t), with 300-series alloy RBS shipments declining by the largest amount in the year, falling 11.9% to 61.3Mlb (27,800t).
  •  
    According to Aurubis Buffalo's vice president of marketing and sales, demand for brass mill products in the US has been strong so far in 2013. The company has seen a strong pickup in demand from sectors including ammunition, electronics, heating and HVAC so far this year. The executive said that lead times at service centers were longer than eight weeks in January for flat-rolled products and that the company is considering hiring more workers at its Buffalo operation to meet the demand.
  •  
    The demand for copper flat-rolled products softened coming into March after a strong start to the year, according to sources at some US service centers. Lead times for some copper products, which were quoted as long as eight weeks back in January, may have shorted to six weeks or less in March according to an American Metal Market report. A drop in demand for appliances and connectors market was noted by some sources contacted by AMM, but sales of ammunition, a key end-use of flat-rolled brass, have remained buoyant since the start of the year.

Yukon`s Carmacks copper project gets YESAB approval - 0 views

  • 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.
  • "The Executive Committee recommends...the Project be allowed to proceed without a review, subject to specified terms and conditions, since it has determined that the Project will have significant adverse environmental and socio-economic effects in the Yukon that can be mitigated by those terms and conditions." Basically, the board reported that if the operators spend enough money and devote sufficient time environmental risks can be addressed.
