ESNA spoke with ReSolve, part of Arrow's newly launched reverse logistics group, which also includes Intechra, an IT asset disposition services company and Converge, an independent distributor, to discuss the importance of a reverse supply chain logistics program. 
The aftermath of Japan's earthquake last month has left the electronics supply chain struggling with production stoppages and shipment delays of electronic components and raw materials supply.
Because the DRAM market is highly volatile the current buyer's market could quickly swing into a seller's market during the second half of 2011. Buyers will need to keep an eye on several key issues.
NREL, Siemens Energy announce 2.3-MW wind turbine project
Washington, D.C. — The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) and Siemens Energy Inc. have launched the biggest government-industry multi-year research project to study the performance and reliability of a new class of large wind turbines.
The centerpiece of the project is a newly commissioned 2.3-megawatt (MW) Siemens wind turbine at NREL’s National Wind Technology Center. The giant turbine is mounted atop a 262-foot tower and fitted with a 331-foot-diameter rotor to the electrical grid.
Under their Cooperative Research and Development Agreement, Siemens and NREL will test basic turbine characteristics and verify new performance enhancing features of the pilot turbine over a minimum period of three years, according to the DOE. Testing will include a full range of real-world operating regimens, including severe weather conditions.
The Siemens 2.3 MW-turbine is among the largest land-based turbines deployed in the United States. Planned testing includes: structural and performance testing, modal, acoustics and power quality testing, aerodynamic testing, and turbine performance enhancements.
NREL has also entered into a separate agreement with Renewable Energy Systems Americas (RES) to study the design and performance of turbine foundations, with the aim of increasing the reliability of non-turbine components and reducing turbine installation costs.
A new meteorological tower to the west of the turbine will feature more than 60 instruments to collect comprehensive data on wind, temperature, dew point, precipitation and other weather features that can influence the performance and lifespan of a wind turbine.
The new turbine and other new projects underway at the National Wind Technology Center also allow NREL to generate its own clean electricity to meet the lab’s sustainability goals, including reduction of greenhouse gas emissions. DOE, NREL, and Xcel Energy are on an agreement for surplus energy to be exported and sold to the local utility grid.
This turbine project is part of a coordinated wind research program that is supported by DOE’s Wind and Hydropower Technologies Program in the Office of Energy Efficiency and Renewable Energy.

It seems there were many news for this project in these days. DOE provide millions dollars to some university and institutes.
Hope this will bring us a new generation large wind turbine.
