Solar CCTV To Curb Crime

Scotland-based renewable energy start-up Puurgen has installed a solar-powered CCTV system at Scottish Water's site in Aberdeen to help combat fly-tipping.
The system features a vandal-proof dome camera powered by a 180 Watt-peak solar power system, which uses Puurgen's innovative maximum power point tracker technology to increase solar capture by up to 40%. The same technology has been used by Puurgen's sister company Clyde Space to power small satellites in space.
The solar-powered CCTV system is completely autonomous and carbon-friendly. No underground channels need to be dug to power the device and the video feed is transmitted via a 2.4GHz wireless link to a nearby secure digital video recorder.
"We are excited about using renewable energy for important environmental challenges such as fly-tipping and are delighted that Scottish Water value the benefit of such a system", said John Charlick, managing director of Puurgen.
"Scotland receives 60% of the sun incident at the equator, making solar power an attractive proposition for remote, off-grid and wireless systems."
Puurgen hope to install similar systems for local councils throughout the UK to help reduce fly-tipping and other types of crime.

Solar Panels Power Henkel's Laundry Labs

The washers and dryers in the laundry laboratories at Henkel's new North American consumer products headquarters in Scottsdale are now running on solar power, thanks to the recent installation of solar panels on the roof of the building.
The solar panels will provide 56,700 kilowatts of electricity a year to run the washers and dryers in the labs.
Excess power from the solar panels is fed into the building grid. Henkel estimates that the solar panels will offset 83,000 pounds of carbon dioxide a year and 2.9 million pounds of carbon dioxide over the life of the system.
Henkel uses the washers and dryers in its laundry labs to develop and test innovative new laundry products such as Purex Complete 3-in-1(TM) laundry sheets, which combine detergent, fabric softener and anti-static in one sheet.
Henkel is also in the process of installing a solar thermal water heating system that will provide hot water for the laboratories. This system will provide 15 million BTUs of energy per year and will offset 28,000 pounds of carbon dioxide a year.
The new headquarters building, which was dedicated on March 3, 2009, is home to 800 employees who develop and market some of America's best-known consumer brands, including Dial soaps and body washes, Purex laundry detergents, Renuzit air fresheners, and Right Guard antiperspirants.
The 348,000 square foot building is located at the intersection of North Scottsdale Road and the 101 Freeway.

Would NHS staff Go To Work During A Flu Pandemic

A survey of health care workers has revealed that as many as 85% may stay off work if an influenza pandemic did take hold of the country. The results of the survey, published in the open access journal BMC Public Health, suggest that levels of absenteeism may be significantly higher than current official estimates and that 'willingness', rather than 'ability', plays the largest role in health care workers' decisions as to whether to go to work or not.
Researchers from the University of Birmingham carried out the survey, in which 1032 healthcare workers responded to questions about the factors that may influence their decisions whether or not to work during an influenza pandemic, and what interventions might be effective in persuading them to work. The research team report that as pandemic influenza is recognised by the Government to be one of the most severe national risks, it is essential that health services are able to manage the major demands that will be placed upon them.
Healthcare workers will be at the forefront of the response to a pandemic, and if services are to be provided at sufficient levels, absenteeism from work must be minimized.
Responses suggest that the likelihood of working may differ by job type. While doctors were more likely to say they would attend, nurses and ancillary staff were more likely to say they would stay away. The survey shows that willingness to work during a pandemic will be strongly impacted by two types of factors. Firstly, issues relating to family and caring responsibilities. Workers with children or elderly family for whom they are carers would be more likely to be absent from work if influenza illness at home (or the possibility of it) became a worry.
Second, issues relating to the work environment itself. These included the possibility of having to take on duties for which a worker felt they had not received training, being asked to work at a different place to normal, working with untrained people, or fears of possible future litigation if mistakes were made while working under abnormal conditions.
Measures intended to persuade health care workers to work as normal during a pandemic will need to be tailored to different job types. But as the research suggests, the groups who may be most in need of suitable interventions may also be the least receptive.
The team conclude, "Potential levels of absenteeism may be significantly higher than current official estimates, and that absenteeism could be particularly marked amongst certain groups of workers." This research provides important information to assist with planning for a potential influenza pandemic.

Armed ship with nuclear fuel arrives in Japan: witness

An armed vessel carrying a massive load of recycled nuclear fuel arrived in Japan on Monday from France, an AFP correspondent witnessed. The Pacific Heron, a specially adapted ship with a British police team on board to head off possible hijackers, arrived in the central port of Omaezaki more than two months after it left France in March.
The convoy, carrying the MOX fuel -- a blend of plutonium and reprocessed uranium -- is expected to unload part of the shipment here and continue its journey to two other ports by nuclear plants in southwestern Japan. Officials have not revealed where and when the shipment will be unloaded, citing fears of terrorist attacks.
Three Japanese power companies -- Kyushu Electric, Shikoku Electric and Chubu Electric -- have said they ordered the MOX fuel reprocessed by French nuclear giant Areva. Japan, which has almost no energy resources, is looking to start using MOX as nuclear fuel for the first time to support the world's second largest economy.

AREVA Aligns With Microsoft For Smarter Grid Solutions

AREVA's Transmission and Distribution (T and D) division has announced the extension of its three-year long collaboration with Microsoft to include the development of Smarter Grid Management solutions to help the worldwide power industry efficiently and reliably fulfill the future global demand for power.
AREVA and Microsoft's joint efforts have already led to the delivery of key capabilities to AREVA customers. Through this new agreement, both companies will work together towards improving cyber security and integration of AREVA's applications with Microsoft Office tools and enterprise business processes.
AREVA's T and D division sees Microsoft technology as a strategic facilitator for the development and deployment of smart grid solutions.
AREVA's T and D Automation division is a recognized leader in the Smart Grid application field with multiple solutions already in use by major utilities worldwide and a number one position in Energy Management Systems, in numerous regions including North America, India, and the Middle East.
The company's initiatives in the smart grid arena are delivering tools and applications for smarter dispatch, integrated distribution management, and demand response. As a result, power companies will see fewer, shorter outages, and shorter service restoration times.

Huge Oil Slicks Generated From Seeps At Coal Oil Point

Twenty years ago, the oil tanker Exxon Valdez was exiting Alaska's Prince William Sound when it struck a reef in the middle of the night. What happened next is considered one of the nation's worst environmental disasters: 10.8 million gallons of crude oil spilled into the pristine Alaskan waters, eventually covering 11,000 square miles of ocean. Now, imagine 8 to 80 times the amount of oil spilled in the Exxon Valdez accident.
According to new research by scientists from UC Santa Barbara and the Woods Hole Oceanographic Institution (WHOI), that's how much oil has made its way into sediments offshore from petroleum seeps near Coal Oil Point in the Santa Barbara Channel. Their research, reported in an article being published in the May 15 issue of Environmental Science and Technology, documents how the oil is released by the seeps, carried to the surface along a meandering plume, and then deposited on the ocean floor in sediments that stretch for miles northwest of Coal Oil Point.
In addition, the research reveals that the oil is so degraded by the time it gets buried in the sea bed that it's a mere shell of the petroleum that initially bubbles up from the seeps. "These were spectacular findings," said Christopher Reddy, a marine chemist at WHOI and one of the co-authors of the new paper.

Cold Water Ocean Circulation Doesn't Work As Expected - Detailed Research Report....

The familiar model of Atlantic ocean currents that shows a discrete "conveyor belt" of deep, cold water flowing southward from the Labrador Sea is probably all wet.
New research led by Duke University and the Woods Hole Oceanographic Institution relied on an armada of sophisticated floats to show that much of this water, originating in the sea between Newfoundland and Greenland, is diverted generally eastward by the time it flows as far south as Massachusetts.
From there it disburses to the depths in complex ways that are difficult to follow.
A 50-year-old model of ocean currents had shown this southbound subsurface flow of cold water forming a continuous loop with the familiar northbound flow of warm water on the surface, called the Gulf Stream.
"Everybody always thought this deep flow operated like a conveyor belt, but what we are saying is that concept doesn't hold anymore," said Duke oceanographer Susan Lozier. "So it's going to be more difficult to measure these climate change signals in the deep ocean."
And since cold Labrador seawater is thought to influence and perhaps moderate human-caused climate change, this finding may affect the work of global warming forecasters.
"To learn more about how the cold deep waters spread, we will need to make more measurements in the deep ocean interior, not just close to the coast where we previously thought the cold water was confined," said Woods Hole's Amy Bower.
Lozier, a professor of physical oceanography at Duke's Nicholas School of the Environment and Bower, a senior scientist in the department of physical oceanography at the Woods Hole Institution, are co-principal authors of a report on the findings to be published in the May 14 issue of the research journal Nature.
Their research was supported by the National Science Foundation.
Climatologists pay attention to the Labrador Sea because it is one of the starting points of a global circulation pattern that transports cold northern water south to make the tropics a little cooler and then returns warm water at the surface, via the Gulf Stream, to moderate temperatures of northern Europe.
Since forecasters say effects of global warming are magnified at higher latitudes, that makes the Labrador Sea an added focus of attention. Surface waters there absorb heat-trapping carbon dioxide from the atmosphere. And a substantial amount of that CO2 then gets pulled underwater where it is no longer available to warm Earth's climate.
"We know that a good fraction of the human caused carbon dioxide released since the Industrial revolution is now in the deep North Atlantic" Lozier said. And going along for the ride are also climate-caused water temperature variations originating in the same Labrador Sea location.
The question is how do these climate change signals get spread further south? Oceanographers long thought all this Labrador seawater moved south along what is called the Deep Western Boundary Current (DWBC), which hugs the eastern North American continental shelf all the way to near Florida and then continues further south.
But studies in the 1990s using submersible floats that followed underwater currents "showed little evidence of southbound export of Labrador sea water within the Deep Western Boundary Current (DWBC)," said the new Nature report.
Scientists challenged those earlier studies, however, in part because the floats had to return to the surface to report their positions and observations to satellite receivers. That meant the floats' data could have been "biased by upper ocean currents when they periodically ascended," the report added.
To address those criticisms, Lozier and Bower launched 76 special Range and Fixing of Sound floats into the current south of the Labrador Sea between 2003 and 2006. Those "RAFOS" floats could stay submerged at 700 or 1,500 meters depth and still communicate their data for a range of about 1,000 kilometers using a network of special low frequency and amplitude seismic signals.
But only 8 percent of the RAFOS floats' followed the conveyor belt of the Deep Western Boundary Current, according to the Nature report. About 75 percent of them "escaped" that coast-hugging deep underwater pathway and instead drifted into the open ocean by the time they rounded the southern tail of the Grand Banks.
Eight percent "is a remarkably low number in light of the expectation that the DWBC is the dominant pathway for Labrador Sea Water," the researchers wrote.
Studies led by Lozier and other researchers had previously suggested cold northern waters might follow such "interior pathways" rather than the conveyor belt in route to subtropical regions of the North Atlantic. But "these float tracks offer the first evidence of the dominance of this pathway compared to the DWBC."
Since the RAFOS float paths could only be tracked for two years, Lozier, her graduate student Stefan Gary, and German oceanographer Claus Boning also used a modeling program to simulate the launch and dispersal of more than 7,000 virtual "efloats" from the same starting point.
"That way we could send out many more floats than we can in real life, for a longer period of time," Lozier said.
Subjecting those efloats to the same underwater dynamics as the real ones, the researchers then traced where they moved. "The spread of the model and the RAFOS float trajectories after two years is very similar," they reported.
"The new float observations and simulated float trajectories provide evidence that the southward interior pathway is more important for the transport of Labrador Sea Water through the subtropics than the DWBC, contrary to previous thinking," their report concluded.
"That means it is going to be more difficult to measure climate signals in the deep ocean," Lozier said. "We thought we could just measure them in the Deep Western Boundary Current, but we really can't."
