A new audit of the Department of Energy’s $34 billion loan guarantee program said the agency doesn’t always follows its own rules in awarding the highly coveted funding, creating risk in an effort already hindered by breakdowns. The audit by the Government Accountability Office carries fresh relevance amid the bankruptcies of two of the first three firms to land the government’s green energy funding: Solyndra Inc. and Beacon Power Corp. “What we found was problems in how they followed their process and in some cases deviated from the process without a clear explanation why,” Frank Rusco, the GAO auditor who wrote the report, said in an interview. “This has gotten the program in trouble in the past and certainly raises questions that are hard for them to answer.” The GAO report, the latest to spotlight vulnerabilities in the way DOE awards public money, details just how selective the loan pool is.
Of 460 applicants, the GAO found, the Energy Department awarded loan guarantees to 7 percent and committed to 2 percent more. To date, the investigative arm of Congress said, the department has issued $15 billion in guarantees and committed to $15 billion more. The GAO scrutinized 13 winning applications in detail. Of those, it found, the Energy Department did not follow its written procedures at least once in 11 of the 13 cases. Read more ..
The Race for Alternative Energy
|Lynn Yarris||March 15th 2012|
A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In subsequent tests, these methyl ketones yielded high cetane numbers – a diesel fuel rating comparable to the octane number for gasoline – making them strong candidates for the production of advanced biofuels. “Our findings add to the list of naturally occurring chemical compounds that could serve as biofuels, which means more flexibility and options for the biofuels industry,” says Harry Beller, a JBEI microbiologist who led this study. “We’re especially encouraged by our finding that it is possible to increase the methyl ketone titer production of E. coli more than 4,000-fold with a relatively small number of genetic modifications.”
Beller directs the Biofuels Pathways department for JBEI’s Fuels Synthesis Division, and also is a senior scientist with the Earth Sciences Division of Lawrence Berkeley National Laboratory (Berkeley Lab). He is the corresponding author of a paper describing this work titled “Engineering of Bacterial Methyl Ketone Synthesis for Biofuels,” which was published in the journal Applied and Environmental Microbiology. Co-authoring this paper were Ee-Been Goh, who is the first author on the paper, plus Edward Baidoo and Jay Keasling. Read more ..

On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city’s unprecedented effort to brighten rooftops and reduce its urban heat island effect.
The dark, sunlight-absorbing surfaces of some New York City roofs reached 170 degrees Fahrenheit on July 22, 2011, a day that set a city record for electricity usage during the peak of a heat wave. But in the largest discrepancy of that day, a white roofing material was measured at about 42 degrees cooler. The white roof being tested was a low-cost covering promoted as part of Mayor Michael Bloomberg’s effort to reduce the city’s greenhouse gas emissions 30 percent by 2030.
On average through the summer of 2011, the pilot white roof surface reduced peak rooftop temperature compared to a typical black roof by 43 degrees Fahrenheit, according to the study, which was the first long-term effort in New York to test how specific white roof materials held up and performed over several years.

Edge of Geopolitics
|George Friedman||March 13th 2012|
The United States has significantly increased its natural gas production since 2005, largely because of advancements in extraction technology. These technological improvements are relatively new, so their exact long-term impact on U.S. production is currently unclear. However, in the short term, this increased production has caused domestic prices to decrease substantially.
To remain profitable, U.S. companies are making plans to begin exports in the form of liquefied natural gas (LNG), which could lead the United States to become a net exporter of natural gas in the next few years. With prices for natural gas higher in East Asia and Europe, the United States can use these exports as an effective economic and political tool. Read more ..
The Race for Solar
|Paul Buckley||March 13th 2012|
At Geneva International Airport SRB Energy has delivered the first of the solar panels that will form one of the largest solar energy systems of Switzerland. Ultimately, some 300 high-temperature solar thermal panels will cover a surface of 1 200 square meters on the roof of the airport’s main terminal building. The panels, which will be used to keep the buildings warm during the winter and cool in the summer, are derived from vacuum technology developed at CERN for particle accelerators.
“We are delighted that Geneva International Airport has opted for this technology,” said Cristoforo Benvenuti, the inventor of the panels, who has been working on vacuum technology at CERN since the 1970s. “The panels emerged from vacuum technologies that were developed for fundamental physics purposes, and it is highly gratifying to see them put to use for renewable energy.” Read more ..
The Race for Nuclear
|Corbin Hiar||March 12th 2012|
One year ago on March 11, an earthquake off the coast of Japan and the resulting tsunami triggered a month-long partial meltdown of the Fukushima Daiichi Nuclear Power Station. In the days leading up to the anniversary of the crisis, advocates and opponents of nuclear power are squaring off in a fight over the lessons U.S. regulators should learn from the disaster.
But both sides are making policy recommendations without a full accounting of the facts. The most definitive, independent study of the disaster isn’t due to be released for months.
In one corner, and at one press conference this week, advocates at the industry-funded Nuclear Energy Institute were eager to highlight the “diverse and flexible” response operators of America’s 104 reactors are taking to improve their disaster preparedness. NEI is touting the $100 million the industry is investing in some 300 additional emergency pumps, generators, and batteries that it says could be used to keep the pools that spent fuel rods are kept in from overheating like they did in Japan.

Nuclear Regulatory Commission (NRC) Chairman Gregory Jaczko hopes to speed up safety reforms planned after the disaster at Japan’s Fukushima Daiichi plant after acknowledging recently that the five-year schedule had slipped.
“That’s something that we really need to focus on and figure out if there aren’t ways we can accelerate that work and really get it all done within five years,” Jaczko said in an interview broadcast on March 11, the one-year anniversary of the massive earthquake and tsunami that hit Japan.
“Nobody wants to be dealing with the lessons learned from Fukushima in six years from now, seven years from now, in eight years from now, there will be other things that come up, other issues that need to be identified and dealt with, and if we are still working on the Fukushima things, it will make it all that much more challenging to deal with these other issues,” he told Platts Energy Week TV.

The Water's Edge
|Brian Nitz||March 11th 2012|
People who live in Mideastern coastal cities might understand the despair expressed in Samuel Taylor Coleridge’s Rime of the Ancient Mariner: “Water, water every where, and nor any drop to drink.”
The poem details the effects of saltwater and thirst on marooned sailors. The ancient mariner hangs an albatross around his neck as an act of atonement for killing this bird, which his shipmates considered to be a good omen. He would not have known that the albatross has desalination glands behind its eyes. These glands concentrate salt and channel it away onto the beak. Some seabirds then sneeze the salt away.
Undrinkable saltwater stretches beyond the horizon from Alexandria, Beirut, Tel Aviv, Abu Dhabi and elsewhere in the Mideast. Fortunately, humans are now able to remove salt from seawater. Israel will soon use desalination for 75 percent of its water supply. But all existing methods are energy intensive and can have significant environmental side effects. The energy cost of desalination is so high that it can be cheaper to transport fresh water hundreds of miles even when there is a great sea on your doorstep. Libya, for example, has plans to purchase fresh water which will be shipped from the Manavgat river in Turkey. Read more ..
Japan After the Meltdown
|Jim Erickson||March 11th 2012|
A year after the crisis at Japan's Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.
In a review article in this week's edition of the journal Science, U-M's Rodney Ewing and two colleagues call for an ambitious, long-term national research program to study how nuclear fuels behave under the extreme conditions present during core-melt events like those that occurred at Fukushima following the March 11, 2011, magnitude 9.0 earthquake and tsunami.
Three of the plant's six boiling-water reactors suffered partial core-melt events that involved tremendously high temperatures and powerful radiation fields, as well as interaction between seawater and nuclear fuel. Many tons of seawater were used to cool the overheated reactors and nearby spent-fuel storage ponds, and direct discharge of contaminated seawater to the ocean and groundwater occurred through approximately April 8.

Ever wondered who the nuclear defense community suports in Congress? Wonder no more. In mid-February, a group of House Republicans sent a letter to President Barack Obama expressing “deep concern” about possible future cuts to the strategic nuclear arsenal reportedly being considered by the administration. Some of the options — including two that would at least halve the arsenal’s current size — would by many accounts undermine the rationale for spending billions of dollars on new strategic bombers, missiles and submarines over the next decade.

The Toxic Edge
Lawrence Berkeley Laboratory
Approximately 45 percent of electricity used in the United States is produced by coal-burning power plants that spew carbon dioxide (CO2) into the atmosphere and contribute to global warming. To reduce this effect, many researchers are searching for porous materials to filter out the CO2 generated by these plants before it reaches the atmosphere, a process commonly known as carbon capture. But identifying these materials is easier said than done.
“There are a number of porous substances—including crystalline porous materials, such as zeolites, and metal-organic frameworks—that could be used to capture carbon dioxide from power plant emissions,” says Maciej Haranczyk, a scientist in the Lawrence Berkeley National Laboratory’s (Berkeley Lab) Computational Research Division.

Industry observers opine that while there may have been a dip in discussion about electric vehicles, as evidenced by the recent Geneva Motor Show where e-cars did not take center stage, much in contrast to the past few years. However, behind the stages, the industry is feverishly working on the design of electric vehicles. Recently, a research project has been launched that addresses the software architecture for electric cars.
Siemens Corporate Technology researchers are working with partners to develop new information and communications technology (ICT) for future electric cars. In vehicles built with this new technology, the driver assistance, safety, and infotainment features will mostly be installed as software instead of being managed in separate control units.

|Home alternative energy system with connections needing isolation (in red)|
Home energy systems based on renewable sources such as solar and wind power are becoming more popular among consumers and gaining increasing support from governmental bodies. Such systems, however, need fault protection in order to achieve the product lifetime that consumers demand as well as isolation to ensure consumer safety. Integrating the two capabilities can help simplify system design as well as lower cost.
The typical renewable energy system has multiple parts operating in different voltage domains. At one end of the system are the power sources, such as solar panels, wind turbine generators, and batteries. The primary power sources—solar panels and wind generators—typically include some form of power conditioning. Read more ..

Leafcutter ants, the tiny red dots known for carrying green leaves as they march through tropical forests, are also talented farmers that cultivate gardens of fungi and bacteria. Ants eat fungi from the so-called fungal gardens, but the bacteria's role has been unclear until now.
New research shows the bacteria help decompose the leaves and play a major role in turning the leaves into nutrients that may be important for both ants and fungi. "This research provides some of the first tangible details about the fascinating symbiotic relationship between leafcutter ants, fungi and bacteria," said Kristin Burnum, a bioanalytical chemist at the Department of Energy's Pacific Northwest National Laboratory. Burnum is a co-author on the paper and led the study's protein analysis. "Understanding how bacteria turn plant matter into a source of energy in ant fungal gardens could also help improve biofuel production." The gardens in question are initially sowed by the ants, which bring leaf pieces into their underground nests. From the leaves grow the fungus Leucoagaricus gongylophorus, traditionally thought of as the ants' food. The relationship between leafcutter ants and fungi has been known since 1874, but it wasn't until the late 1990s that scientists started to also identify bacteria in the underground gardens.

The Edge of Energy
|Megan Fellman||March 2nd 2012|
A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA damage and cancer in the human body.
In a new study, Northwestern University scientists turned to squeezed polymers and free radicals in a search for new energy sources. They found incredible promise but also some real problems. Their report is published by the journal Angewandte Chemie.
The researchers demonstrated that radicals from compressed polymers generate significant amounts of energy that can be used to power chemical reactions in water. This energy has typically been unused but now can be harnessed when polymers are under stress in ordinary circumstances -- as in shoe soles, car tires or when compacting plastic bags. Read more ..

Researchers of the DFKI Robotics Innovation Centre in Bremen have developed a smart electric car with flexible morphology that can change its shape according to the current needs. The prototype has been built in the scope of a project "New mobility in rural spaces" which among other topics explores innovative technologies associated to electromobility.
The EO smart connecting car disposes of a flexible undercarriage which enables multiple vehicles to be connected to a single "road train". When the undercarriage is folded together, the driver cabin is automatically moved into a vertical position. Thus, the vehicle reduces its overall length by about half a meter to a total of about 2 meters. Conversely, its height grows from 1.60 meters to about 2 meters. This change in shape facilitates the formation of so called road trains: Shorter vehicles result in a shorter, more agile train. "If multiple vehicles have to travel over the same distance, they can effectively connect to each other and increase energy efficiency", explained Fank Kirchner, head of the DFKI Robotics Innovation Center. "Data and energy are carried over among the vehicles and only the front vehicle steers the train." Read more ..
The Toxic Edge
A much-anticipated government study of more than 12,000 miners — whose publication was delayed by litigation from a group of mining companies — has found that exposure to diesel engine exhaust significantly increases the risk of lung cancer.
For the most heavily exposed miners, the risk of dying from lung cancer was three times higher than it was for those exposed to low doses. For non-smokers, the risk was seven times higher.
“[T]he findings suggest that the risks may extend to other workers exposed to diesel exhaust in the United States and abroad, and to people living in urban areas where diesel exhaust levels are elevated,” Joseph Fraumeni Jr., director of the National Cancer Institute’s Division of Cancer Epidemiology and Genetics, said in a press release Friday morning.

On Israeli prime minister Binyamin Netanyahu recently visited Cyprus, only three months after a similar trip by President Shimon Peres.
The state visits followed a series of ministerial-level meetings to discuss the development of newly discovered offshore natural gas fields and a range of associated diplomatic and security complexities relating to neighboring Turkey and Lebanon. Both Israel and Cyprus have found enough gas in their maritime exclusive economic zones (EEZs) to satisfy domestic demand for many years, with additional quantities available for export, but managing regional diplomatic tension over these resources may prove tricky. Netanyahu’s trip to Cyprus, the first by an Israeli prime minister, reflects increasing cooperation between the two countries over natural gas resources but will likely heighten tensions with Turkey.

Lewis Strauss, Chairman of the US Atomic Energy Commission said this to a group of science writers in 1954: “Our children will enjoy in their homes electrical energy too cheap to meter…” While this comment is often given as an example of overly-optimistic technological predictions, electricity is incredibly inexpensive. Just look at how much is wasted illuminating the night sky.
Would Strauss have ever imagined that people would be able to afford the energy required to make it snow in Dubai? Or that the hundreds of megawatt-hours used to remove salt from seawater would cost less than fresh water?
Sony intends to solve this “too cheap to meter” problem by lowering the cost of metering small amounts of electricity and by making it possible to measure electricity usage for individuals and their devices with smart sockets. Read more ..
The Race for Fuel
|Kiyotada Hayashi||February 26th 2012|
A life cycle assessment of growing crops for fuel as opposed to refining and using fossil fuels has revealed that substitution of gasoline by bioethanol converted from energy crops has considerable potential for rendering our society more sustainable, according to a Japanese study published in the International Journal of Foresight and Innovation Policy.
Kiyotada Hayashi of the National Agriculture and Food Research Organisation in Tsukuba and colleagues explain how biomass derived from sugarcane, sugar beet and other crops, has emerged as one of the most promising renewable energy sources. Some observers suggest that it makes an excellent substitute for oil-derived fuels and it is being used widely in certain parts of the world already. However, there are concerns about land use and the overall life-cycle impact on raising fuel crops and the energy required to process and exploit biomass compared with fossil fuels. The Japanese team has now put to rest some of those concerns in a life cycle assessment of energy crop production for bioethanol in Japan.
The team hoped to clarify the potential of biomass utilisation while taking into account the cumulative fossil energy demand and climate change impact. They looked at two scenarios: one in which cultivation technologies improves and breeding of new crop varieties is made possible. The second scenario looked at how the establishment of regional biomass utilisation systems that used biomass resources from various industries might function mutually and effectively and again reduce fossil fuel demand and reduce carbon emissions.

It takes a lot of energy to extract heavy, viscous and valuable bitumen from Canada's oil sands and refine it into crude oil. Companies mine some of the sands with multi-story excavators, separate out the bitumen, and process it further to ease the flow of the crude oil down pipelines. About 1.8 million barrels of oil per day in 2010 were produced from the bitumen of the Canadian oil sands—and the production of those fossil fuels requires the burning of fossil fuels. In the first look at the overall effect of air pollution from the excavation of oil sands, also called tar sands, in Alberta, Canada, scientists used satellites to measure nitrogen dioxide and sulfur dioxide emitted from the industry. In an area 30 kilometers (19 miles) by 50 kilometers (31 miles) around the mines, they found elevated levels of these pollutants. "For both gasses, the levels are comparable to what satellites see over a large power plant—or for nitrogen dioxide, comparable to what they see over some medium-sized cities," said Chris McLinden, a research scientist with Environment Canada, the country's environmental agency. "It stands out above what's around it, out in the wilderness, but one thing we wanted to try to do was put it in context." Read more ..

U.S. companies are looking to invest in projects to boost electricity in Africa, which has long been one of the biggest impediments to broader economic growth on the continent. U.S. Deputy Assistant Secretary of State William Fitzgerald says an energy trade mission to Ghana, Nigeria, Tanzania, and Mozambique showed vast potential for American firms to invest in African energy projects. In Nigeria, Fitzgerald says U.S. firms will be among those who bid on the privatization of power plants and power distribution networks. Bids are due by June for contracts expected to be announced by October in a country where estimated demand tops 10,000 Megawatts but regular supply is less than 4,000 Megawatts. “Thirty-nine hundred Megawatts is a woefully small amount, and the Nigerian government realizes to promote - certainly to diversify the economy - to bring the manufacturers back on line they need to boost power," said Fitzgerald.
In Ghana, Fitzgerald says many U.S. firms are interested in offshore oil and natural gas, especially if Ghana and Ivory Coast resolve differences over the location of their maritime border. “It is an exciting time to be in the energy sector in Ghana," he said. "And I think what you are seeing is very much of a commitment on the part of the Ghanian government to embrace private sector companies to come in and do the work. You are going to see employment levels increasing and reaching record heights. Part and parcel of that you will also see education improving, health sector clinics improving.” Read more ..
The Race for Biofuel
|Patrick J. Callahan||February 18th 2012|
A team of chemical engineers at the University of Massachusetts Amherst has discovered a small molecule that behaves the same as cellulose when it is converted to biofuel. Studying this ‘mini-cellulose’ molecule reveals for the first time the chemical reactions that take place in wood and prairie grasses during high-temperature conversion to biofuel. The new technical discovery was reported in the January 2012 issue of the journal Energy & Environmental Science and highlighted in Nature Chemistry.
The "mini-cellulose" molecule, called α-cyclodextrin, solves one of the major roadblocks confronting high-temperature biofuels processes such as pyrolysis or gasification. The complex chemical reactions that take place as wood is rapidly heated and breaks down to vapors are unknown. And current technology doesn’t allow the use of computer models to track the chemical reactions taking place, because the molecules in wood are too large and the reactions far too complicated.

The Race for Batteries
|Stephanie Hobby||February 18th 2012|
Sandia researchers have developed a new family of liquid salt electrolytes, known as MetILs, that could lead to batteries able to cost-effectively store three times more energy than today’s batteries.
The research, published in Dalton Transactions, might lead to devices that can help economically and reliably incorporate large-scale intermittent renewable energy sources, like solar and wind, into the nation’s electric grid.
The grid was designed for steady power sources, making fluctuating electricity from intermittent renewable energy difficult to accommodate. Better energy storage techniques help even out the flow of such fluctuating sources, and Sandia researchers are studying new ways to develop a more flexible, cost-effective and reliable electric grid with improved energy storage.

There is an ever-increasing need for advanced batteries for portable electronics, such as phones, cameras, and music players, but also to power electric vehicles and to facilitate the distribution and storage of energy derived from renewable energy sources. But, once a battery fails, there are no corrective measures—how do you look inside a battery without destroying it?
Now, researchers at Cambridge University, Stony Brook University, and New York University have developed methodology, based on magnetic resonance imaging (MRI), to do just that. Their technique, which is described in the journal Nature Materials, also creates the possibility of improving battery performance and safety by serving as a diagnostic of its internal workings.

An outside consultant hired by the White House to assess the Department of Energy’s hot-button green energy loan program suggests the agency hire a “chief risk officer” to better track companies backed by taxpayer-funded loans.
“To enhance the independence of the oversight function, DOE should create a new Risk Management department,” wrote Herbert Allison, the independent consultant. That conclusion is among the core recommendations detailed in the 75-page report, just released.
The report was intended to help resolve concerns triggered by the political backlash over the Obama administration’s failed $535 million investment in upstart solar firm Solyndra, which declared bankruptcy last fall.
But the review never directly addresses Solyndra’s failure, or another DOE-backed green energy venture that went bankrupt, Beacon Power Corp. Allison, a longtime official in the public and private sectors who most recently served as Assistant Secretary of the Treasury for Financial Stability, writes that he “did not evaluate the loans to Solyndra and Beacon” because those companies have already failed. He also notes that his review was less exhaustive than it could have been because it was put on a 60-day fast track by the White House. Read more ..
The Fuel Economy
|Bernie DeGroat||February 9th 2012|
The average fuel economy of current model year vehicles is 14 percent higher than just four years ago, say researchers at the University of Michigan. For all 2012 light-duty vehicles (cars, pickup trucks, minivans, vans and SUVs) offered for sale, average mpg is 21.5, compared to 18.9 mpg for model year 2008 vehicles. The averages were 21.2 for 2011, 20.7 for 2010 and 19 for 2009.
For new vehicles actually purchased, average fuel economy is typically one-to-two miles per gallon higher—22.5 mpg for model year 2011 (the last full year of sales), 22.1 for 2010, 21.3 for 2009 and 20.8 for 2008. "This implies that consumers tend to choose vehicle models with better fuel economy than the average of all vehicles available," said Brandon Schoettle of the U-M Transportation Research Institute. "The recent economic downturn, coupled with rising gas prices, has led to an increased interest in purchasing more fuel-efficient vehicles."
Using data from the EPA, Schoettle and UMTRI colleague Michael Sivak also examined fuel economy changes by vehicle characteristics: cars vs. light trucks, vehicle class size, transmission type, number of engine cylinders, drive type, fuel type and hybrid vs. conventional vehicles. Read more ..

Crystal Lagoons—the company behind the planned world’s largest artificial lagoon for the Red Sea—has developed an alternative cooling and energy harvesting system for power plants that doesn’t require the use of seawater.
Gulf countries that lack freshwater resources rely deeply on seawater desalination to meet their daily needs and cool down thermal generation plants. According to Gulf News, the United Arab Emirates alone uses four trillion litres of Gulf seawater each year to cool down its power plants, foundries, and desalination plants. A report released last year revealed that UAE coastal development has seriously jeopardized the health of the marine environment. This technology has the potential to seriously arrest further damage. The byproduct of these operations produces a hot briny fluid that is then pumped back into the Gulf. But Crystal Lagoons is marketing a new closed-loop cooling system that would ensure that no more water would have to be extracted from the Gulf to cool down industrial plants. Read more ..

To me, as a dedicated free-market capitalist and defender of American ideals, I would like to believe that the story of petroleum oil exploration should be one of entrepreneurial glory. Instead, the more I learn about the corruption and machinations employed by British Petroleum and its industry cohorts and competitors, the more I realize that we have been the victims of oil’s subjugation for well over 100 years.
With the rise of industrialization and the advent of the automobile and other forms of engine-powered transportation, the world needed a standardized source of fuel for the new machines. That fuel could easily have been a fuel produced by virtually anyone using organic materials. However, a fuel based on simple vegetation or human waste, and a common distillation process that couldn't be patented left little on the table for those who sought unbridled power and wealth. British Petroleum and the Redline Agreement reads like the most exciting Tom Clancy novel entwined with a devious international conspiracy worthy of Ian Fleming’s wildest James Bond adventure; although even for a 007 yarn it might run the risk of being considered too implausible a plot.

Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011—and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis.
But Navrotsky and others have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles. The research team published its work in January in the journal Proceedings of the National Academy of Sciences.
“This is a phenomenon that has not been considered before,” said Alexandra Navrotsky, distinguished professor of ceramic, earth, and environmental materials chemistry. “We don’t know how much this will increase the rate of corrosion, but it is something that will have to be considered in future.” Read more ..

Etihad Airways from the United Arab Emirates scores a double play in the Green World Series: It has become both the first airline to fly on biofuel directly from the factory and the first biofuel-flying Gulf carrier. Although, not yet on its fuel-efficient Dreamliners, Etihad’s new Boeing 777-300ER traveled from its Seattle birthplace to its home base at Abu Dhabi International Airport this past Wednesday, powered by a mix of traditional fuel and plant-based biofuel. The biofuel having been created from recycled vegetable cooking oil. Used oil from the food industry qualifies as a bio-based waste stream, its resulting carbon footprint is especially trim.
“This flight marks a significant milestone in our efforts to drive commercialization of sustainable aviation fuel in Abu Dhabi, the region, and globally. Use of presently available biofuel is just part of a comprehensive strategy to ensure that we are able to use biofuel to decarbonize an entire industry sector in the long term”, said Etihad Airways’ President and CEO James Hogan in a public statement.
Financed by $2 million of Etihad funding, this ground-breaking R&D lab is pioneering use of salt water-tolerant plants in production of alternative aviation fuel. As a member of the global Sustainable Aviation Fuel Users Group, the airline is fully committed to developing biofuel feedstocks, which protect drinking water supplies; are non-competitive with food sources and maintain optimal biodiversity.

How can local governments keep public spaces and roads illuminated at night in places where there’s no electricity, or an unreliable supply? Solar power, obviously.
But there’s a catch.
“The vast majority of solar-powered streetlights and similar fixtures on the market don’t survive for long,” according to Zeev Jakoby, managing director of Israeli startup Globe Light & Water System. “That’s why we’ve devised a sturdy, solar-powered light fixture that needs no infrastructure.”
This could prove a godsend to developing nations where a lack of street lighting results in dangerous driving conditions and far slower economies. “It’s designed with the African market in mind,” explains Jakoby, who spent many years in Nigeria overseeing construction projects. Read more ..
The Race for Nuclear
|Aaron Mehta||January 27th 2012|
In the post 9/11 world, the threat of a nuclear bomb being fabricated and used by terrorists is real. Now a group of nuclear experts has told Congress that a loophole in a bill meant to limit the use of bomb-grade uranium in medical isotopes could undo years of work to curb the risk of such material being diverted to such a bomb.
Signed by over a dozen experts in the medical and nuclear non-proliferation fields, the letter raises concerns about the American Medical Isotopes Production Act of 2011, passed by the Senate in November. The bill, currently awaiting a House vote, is aimed at reducing the use of highly-enriched uranium (HEU) in developing the medical isotope Molybdenum-99 — a key ingredient in the medical diagnosis of millions of American patients a year.
Highly-enriched uranium is also a key ingredient in nuclear weapons, and experts say its continuing production for civilian use poses many security risks. The letter, submitted by the Nuclear Proliferation Prevention Project (NPPP), argues that the bill might unintentionally promote the heightened production of HEU by Russia, in particular.

The Race for BioFuel
|Beck Lockwood||January 27th 2012|
The technique builds on previous research in which microbubbles were used to improve the way algae is cultivated. Algae produce an oil which can be processed to create a useful biofuel. Biofuels, made from plant material, are considered an important alternative to fossil fuels and algae, in particular, has the potential to be a very efficient biofuel producer. Until now, however, there has been no cost-effective method of harvesting and removing the water from the algae for it to be processed effectively.
Now, a team led by Professor Will Zimmerman in the Department of Chemical and Process Engineering at the University of Sheffield, believe they have solved the problem. They have developed an inexpensive way of producing microbubbles that can float algae particles to the surface of the water, making harvesting easier, and saving biofuel-producing companies time and money. The research is set to be published in Biotechnology and Bioengineering on 26 January 2012. Read more ..
The Race for EV's
|Christoph Hammerschmidt||January 25th 2012|
The British government and a number of private-public initiatives are successfully building the charging infrastructure for electric vehicles, says Frost & Sullivan. "London has over 500 public charging stations and is dynamically adding more to it", explains Research Associate Prajyot N. Sathe. “The launch of the Source London scheme is working towards getting 1.300 public charging stations by 2013.” By 2015, about 25.000 charging stations will be available in the greater London area. The North East England region also is pushing ahead electromobility infrastructure - the region recently has installed 300 charging stations; the goal is to get 1300 charging stations already in 2013. North East England has been included in the “Plugged-in places” project, that offers matched funding to business and public sectors to install charging stations. They have also been formulated to integrate residential charging stations with a provision for smart meters.
Nissan's strategic use of its Sunderland plant for developing Electric Vehicles (EVs) across Europe has accelerated the government’s vision to increase sustainable and 'green-collar’ jobs. The ambitious targets set by the government and heavy contracts secured by leading EV infrastructure providers are the major grounds for the impressive deployment of the EV charging stations network at strategic locations such as car parks, residential and commercial locations as well as leisure facilities.

The Obama administration’s recent decision to reject a pipeline that would have carried crude from Canada’s tar sands deposits to Texas oil refineries isn’t likely to end investment in the carbon-rich fuel, industry analysts say.
In killing the controversial Keystone XL pipeline, President Obama blamed congressional Republicans, who he said “forced this decision” by requiring an expedited 60-day review of the pipeline as a provision of the recent payroll tax extension. President Obama also reaffirmed his support for domestic oil and gas exploration and expanding fossil fuel infrastructure. “In the months ahead, we will continue to look for new ways to partner with the oil and gas industry to increase our energy security,” he said.

The Race for Solar
|Karin Kloosterman||January 23rd 2012|
With a 35 meter high sun-ray collection tower and about 50 mirrors positioned to direct the sun, Israel’s AORA is about to flip the switch on its latest solar power plant in Spain. The company created a huge buzz in Israel in 2009 when it was the first solar energy company to connect to the national grid.
Since, it has been under the radar, and has recently emerged at the prestigious Platforma Solar Almeria in Almeria, Spain.
The new ultra-high temperature concentrating solar power (CSP) technology it is showcasing there focuses heliostats, small mirrors, onto a sun collecting turbine built on top of the “tulip”. Read more ..
The Race for Wind

By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time.
Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power.
This variable power can be predicted by looking at atmospheric stability, according to Lawrence Livermore National Laboratory scientist Sonia Wharton and colleague Julie Lundquist of the University of Colorado at Boulder and the National Renewable Energy Laboratory.
In a paper appearing in the Jan. 12 edition of the journal Environmental Research Letters, Wharton and Lundquist examined turbine-generated power data, segregated by atmospheric stability, to figure out the power performance at a West Coast wind farm."The depend ence of power on stability is clear, regardless of whether time periods are segregated by three-dimensional turbulence, turbulence intensity or wind shear," Wharton said. The team found that power generated at a set wind speed is higher under stable conditions and lower under strongly unsteady conditions at that location. The average wind power output difference is as high as 15 percent less wind power generation when the atmosphere is unstable. Read more ..
