Focus on climate change in the Arctic could yield environmental and financial dividends, panel concludesMarch 6, 2013 9:36 am | News | Comments
Climate change in the far north is occurring far more rapidly than elsewhere around the planet, but common-sense efforts to mitigate key emissions and protect the fragile Arctic environment could slow this trend and benefit communities, the environment, and companies.
I was reading one of the logistics magazines I regularly get and found out something amazing. By about 2020, roughly 80 percent of the lift trucks in America will be powered by hydrogen fuel cells. The fuel cell advantage is constant voltage output and longer continuous run time.
You are ready and packed to leave on a holiday trip and for the first time, you agreed that your teenage son can stay home alone. The control freak in you is already making long lists of daily and weekly tasks and to-do’s to keep the pets and plants alive, and the calamity predictor in you wants to anticipate for flooded bathrooms and burning fryers.

Canon U.S.A. recently launched sales of the new FPA-3030i5+ i-line stepper. The FPA-3030i5+ is designed to provide a long-term manufacturing solution for manufacturers of energy-efficient, environmentally conscious devices including Light-Emitting Diodes (LEDs),MicroElectroMechanical Systems (MEMS) and power semiconductors.
Historically, TVs have had brightness higher than 400 nits, as they are often placed in the center of a large, bright, room and viewed from large distances and viewing angles. In some cases, however it is placed in sunlight, close to a window. On the other hand, display brightness of less than 300 nits is typically sufficient for an IT device....

RF Micro Devices announced the availability of the RFFM6903 front end module (FEM). RFMD's highly-integrated RFFM6903 FEM meets or exceeds the system requirements for AMI/AMR smart meter applications operating in the 868MHz–960MHz frequency band.
Following a decline in the third quarter of 2012, global photovoltaic (PV) inverter shipments are forecast to reach a record of 8.6 gigawatts (GW), according to the latest report from IMS Research. An 18 percent year-on-year rise in global shipments will make the fourth quarter of 2012...
Energy Micro, Linear Technology and Würth Elektronik present the development platform Energy Harvesting Solution To Go. The Energy Harvesting Solution To Go-Kit provides a very easy access to energy harvesting technologies which helps developers to apply them in future battery less products.
ASU researchers will explore feasibility of large-scale deployment of perennial biomass energy cropsOctober 2, 2012 12:19 pm | by EurekAlert! | News | Comments
Arizona State University (ASU) researchers will embark on a novel renewable energy project with support from the National Science Foundation (NSF) through its Water Sustainability and Climate program (WSC). NSF is providing $1.5 million to ASU to identify suitable locations across the United States where perennial biomass energy crops (e.g., miscanthus and switchgrass) could be grown sustainably.
A team of scientists, led by Joachim Reichert, Johannes Barth, and Alexander Holleitner (Technische Universitaet Muenchen, Clusters of Excellence MAP and NIM), and Itai Carmeli (Tel Aviv University) developed a method to measure photocurrents of a single functionalized photosynthetic protein system.
I have been big on flywheels for electrical energy storage for quite some time. So it was quite a disappointment to me to hear that high tech flywheel company Beacon Power did a Solyndra and reneged on a government loan because it could not finance its debts from income.
Yingli Green Energy and Trina Solar, two of China's largest solar equipment makers, rejected on Wednesday allegations by a group of European solar panel companies that Chinese rivals are benefiting from illegal subsidies. In a complaint to the European Commission on Tuesday, the EU ProSun group said Chinese solar companies benefited from very low interest rates thanks to government policy.
A tiny solar company named SoloPower will flip the switch on production at a U.S. factory Thursday, a major step toward allowing it to tap a $197 million government loan guarantee awarded under the same controversial program that supported failed panel maker Solyndra.
Data Translation today announced the release of the DT8824-HV Ethernet module, extending ultra-accurate, high-stability measurements to high voltage ranges. The DT8824-HV features a standard full scale range of ±600V, with input gains of 1, 8, 16, and 32 to provide effective ranges of: ±600V, ±75V, ±37.5V, and ±18.75V.
Airborne wind energy—an emerging approach to harnessing high-altitude winds—could scale up fairly quickly if given significant government support for research and development, according to a survey of experts by Near Zero, a nonprofit energy research organization.
A new kind of roof-and-attic system field-tested at the Department of Energy's Oak Ridge National Laboratory keeps homes cool in summer and prevents heat loss in winter, a multi-seasonal efficiency uncommon in roof and attic design. The system improves efficiency using controls for radiation, convection and insulation, including a passive ventilation system...
With prosperity rising at a global level the demand for energy has been increasing significantly over the last decade. However, there are concerns of energy supply and distribution to many areas of the world with little or no infrastructure. Furthermore, using fossil fuel as the main energy supply in the long run has been strongly debated.
Material properties and interactions are largely determined by the binding and unbinding of their constituent molecules, but the standard model used to interpret data on the formation and rupturing of molecular bonds suffers from inconsistencies. A collaboration of researchers led by a scientist at the U.S Department of Energy (DOE)'s Lawrence Berkeley National Laboratory...
In the global market for wind converters, nearly 80 percent of revenues in 2011 were attributed to utility-scale onshore projects, but is forecast to account for less than 70 percent of the total market by 2016 due to an expected decline in the United States wind market and the growth of the offshore wind industry...
My local paper says that the wind energy business is likely to slow down in 2013. They explain that it will be bad for a local manufacturer that makes parts for the turbines and who also makes machines to make the parts. When you make 10 ton hubs for the turbines it is best to make them as close to the installation site as possible. Otherwise the shipping costs can ruin your profits.
