The Race for Batteries
|Dianne Kibbey||May 26th 2014|
Another area that innovation in wireless technology can help improve is in home entertainment and electronics, where the issue of batteries really comes to the fore.
Think of the amount of devices you have in your house that are battery-operated remote controls for TVs, Hi-Fi systems and games consoles, childrens toys and in some cases even electronic toothbrushes, razors and hairdryers.
That is a lot of technology that can just run out of power at any time, leaving you hoping that the famous 'turn the batteries around trick works or that you actually have a few spares lying hiding in the back of a drawer somewhere. Thankfully, weve seen some great ideas from finalists in the element14 Community Wireless Power Challenge, providing a far more practical solution to battery-operated equipment.
Hendrik Lipka and Martin Puig, both of Germany, have both addressed wireless power in the home in their entries; suggesting a charger station and wireless power solutions for battery-operated childrens toys and television remotes respectively. Read more ..
The Race for Biofuels

The bright yellow fields of oilseed rape are a familiar sight at this time of year, but for scientists what lies beneath is just as exciting.
Researchers at the Institute of Food Research are looking at how to turn straw from oilseed rape into biofuel. Preliminary findings are pointing at ways the process could be made more efficient, as well as how the straw itself could be improved.
Straw from crops such as wheat, barley, oats and oilseed rape is seen as a potential source of biomass for second generation biofuel production. Currently the UK produces around 12 million tonnes of straw. Although much is used for animal bedding, mushroom compost and energy generation, there still exists a vast surplus.
Straw contains a mix of sugars that could be used as a source of biofuels that do not compete with food production but instead represent a sustainable way of utilising waste. However, the sugars are in a form that makes them inaccessible to the enzymes that release them for conversion into biofuels, so pre-treatments are needed. The pre-treatments make the complex carbohydrates more accessible to enzymes that convert them to glucose, in a process called saccharification. This is then fermented by yeast into ethanol.

The Race for Natural Gas
|Luke Johnson||May 24th 2014|
Russia and China have agreed to a 30-year natural-gas deal that will supply 38 billion cubic meters of gas annually to the world's most populous country, according to Gazprom. Here is what is known about the deal.
What did China and Russia agree to?
Gazprom and the China National Petroleum Corporation agreed to a 30-year deal that would supply the People's Republic with 38 billion cubic meters of natural gas annually, starting in 2018. The terms of the deal remain a secret.
Prior to the announcement of the deal, Russian and Chinese companies agreed to a series of projects that indicate further cooperation in the commercial sphere. Russia's state-owned United Aircraft Corporation and China's Comac signed a memorandum to create a large, long-haul airplane to compete with Airbus and Boeing. Russia and China also agreed to build a cross-border rail bridge over the Amur River by 2016.
What is the price of the deal
The price of natural gas under deal is also, surprise, a secret. Gazprom CEO Aleksei Miller said that the price was a "commercial secret." But he put the total value of the contract at $400 billion. Putin said Russia will invest $55 billion under the deal while China would invest at least $20 billion.
Putin said the price "satisfies both sides. It is pegged to the gas price and gas fuel price, as is the case with all of our international contracts with our Western partners, our partners in Western Europe." Read more ..
China and Russia
|Michael Johnson||May 23rd 2014|
Russian state owned gas company, Gazprom, and China National Petroleum Corporation agreed to a landmark energy contract on Wednesday following a visit by President Vladimir Putin to Shanghai. Starting in 2018, Moscow has agreed to sell over $400 billion worth of natural gas to meet rising Chinese demand over a 30 year period. Although the exact terms of the deal remain unknown, the agreement helps Russia become less dependent on European energy demand.
After many years of negotiations, the finalized contract hands President Putin a much needed victory not only economically but politically as well. Recent trade sanctions and visa bans against Russian firms and officials in response to Moscow's actions in Ukraine have spooked Western investors. While not incredibly strong, the sanctions' symbolic significance probably helped put Russia into recession. Read more ..

A new fuel-cell concept, developed by an Michigan State University researcher, will allow biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production process.
The platform, which uses microbes to glean ethanol from glycerol and has the added benefit of cleaning up the wastewater, will allow producers to reincorporate the ethanol and the water into the fuel-making process, said Gemma Reguera, MSU microbiologist and one of the co-authors.
“With a saturated glycerol market, traditional approaches see producers pay hefty fees to have toxic wastewater hauled off to treatment plants,” she said. “By cleaning the water with microbes on-site, we’ve come up with a way to allow producers to generate bioethanol, which replaces petrochemical methanol. At the same time, they are taking care of their hazardous waste problem.” Read more ..
The Race Garbage to Fuel
|Steve Baragona||May 19th 2014|
When a garbage truck dumps its smelly cargo onto the tipping floor at the Fiberight company’s pilot plant in southern Virginia, manager Randy Garrett sees fuel in the making.
“This is the truly remarkable part,” he said. “This was slated for the landfill. This was going to be buried.”
Fiberight is one of several companies that plans to turn garbage ‒ and in other cases, corn stalks and wheat straw ‒ into biofuel ethanol that can power vehicles, in a development that lends credence to the old adage, "one person's trash is another's treasure."
It's one of the most eagerly awaited technologies in alternative fuel and is expected to break into the mainstream this year.
The biofuel is known as cellulosic ethanol, and if successful, supporters say it could provide an abundant source of energy while quieting critics who say the growth of the biofuel business has put a strain on food prices and the environment.
Ethanol makes up about 10 percent of the U.S. fuel supply and is expected to grow under a 2007 law.
Nearly all of it, however, has been made from corn. Critics say the demand for corn ethanol has created competition between food and fuel that is raising food prices. Environmentalists say farmers are plowing more land to grow corn and using more fertilizers and pesticides, generating more pollution. Read more ..
The Race for EVs
|Paul Buckley||May 18th 2014|
The research results show that none of the vehicle types, including electric-powered cars as well as those powered by hydrogen, petrol and diesel fuels, expose passengers to higher electromagnetic fields than those recommended in international standards. In fact, field intensity is well below the recommended value.
SINTEF led the research project which involved nine other European companies and research institutes.
In addition to improving the publics confidence when it comes to magnetic fields in electric cars, the goal of the project was primarily to create a standardised method for measuring electromagnetic fields in such vehicles. The International Commission on Non-Ionising Radiation Protection (ICNIRP) defines the limiting values of acceptable exposure to magnetic fields at different frequencies. Read more ..
The Race for Solar
|Heather Lammers||May 18th 2014|
Indy-500-style checkered flags, high-tech neoprene rubber tracks, and of course, sponsor decals graced the site of today's Junior Solar Sprint and Lithium Ion Battery car competitions for Colorado's middle schoolers. Nearly 300 students on 74 teams from 21 Colorado schools converged on Dakota Ridge High School to vie for a spot in the final races using solar and lithium ion battery powered vehicles they designed and built themselves.
"We went for lightweight and aerodynamic," Matthew Heitmann with the team from Calhan Middle School. "I'm coming back next year for sure, it's fun."
Each year, the Energy Department's (DOE) National Renewable Energy Laboratory (NREL) and other local sponsors host the races to show middle-school students that science, engineering, and design can be rewarding and to encourage them toward careers in STEM -- science, technology, engineering, and math. The batteries used in the competition are supplied by the DOE and teams purchase authorized solar panels, then design and build the rest of their cars themselves. Solar and lithium ion battery power are highlighted at the competition since they are important research focuses for NREL and DOE. Read more ..
The Race for Natural Gas
|Charles Recknagel||May 15th 2014|
Good diplomats find opportunities in crises, and Iran's policymakers seem to be following the rule.
Amid rising tensions between the European Union and Moscow over Ukraine, Iranian oil officials have repeatedly said Tehran is ready to supply natural gas to Europe, which currently gets 30 percent of its gas imports from Russia.
The offer by Iran, which has the world's second largest natural-gas reserves after Russia, might seem surprising when the EU currently bans the import of Iranian natural gas as part of sanctions over Tehran's nuclear program.
But Iran may hope the energy offer will add incentives for lifting the international sanctions as Tehran and world powers hold talks in Vienna this week aimed at solving the nuclear crisis.
Ghoncheh Tazimi, a scholar at SOAS in London, says "Iran's case has been somewhat strengthened with the Ukraine crisis" because Tehran is "able to shape the future energy market" and help Europe diversify away from Russia. She adds, Iran knows that "energy has always been Russia's bargaining chip and is Europe's Achilles heel." Read more ..
The Race for Batteries
|Paul Buckley||May 14th 2014|
Japanese start-up Power Japan Plus has launched a new battery technology that claims to offer a more sustainable, safer, longer-lasting and cost-effective battery technology with an energy density comparable to a lithium ion battery.
The Ryden dual carbon battery makes use of novel chemistry that sees both the anode and the cathode made of carbon.
Power Japan Plus is a materials engineering company for a new class of carbon material that balances economics, performance and sustainability in a world of constrained resources, said Dou Kani, CEO of Power Japan Plus. The Ryden dual carbon battery is the energy storage breakthrough needed to bring green technology like electric vehicles to mass market. The Ryden battery claims to balance a breadth of consumer demands previously unattainable by single battery chemistry, including performance, cost, reliability, safety and sustainability.

A bill with strong bipartisan support to make the United States more energy efficient has been blocked in the Senate. The Energy Savings and Industrial Competitiveness Act failed to get the three-fifths backing required to proceed to a final vote, becoming the latest victim of partisan warfare on Capitol Hill.
The idea is simple: the U.S. government, as well as homes and businesses across America, should use energy more frugally. Pro-environment Democrats like the bill’s potential to reduce greenhouse gases. Fiscally minded Republicans like the bill’s long term potential to reduce government expenditures on power and fuel. Members of both parties applaud the bill’s potential to boost American jobs. The bill has the backing of environmental and business groups alike. Senate Majority Leader Harry Reid, a Democrat, summed it up this way: Read more ..
The Race for Power Security
Universidad Carlos III de Madrid
In 1928, the British biologist and geneticist John Haldane wrote the essay “On being the right size” in which he stated that “For every type of animal there is a most convenient size, and a large change in size inevitably carries with it a change of form”. The application of Haldane’s Principle spread to fields like physiology and paleontology, and there was speculation that it could be used with institutions and social organizations, as well. And that is precisely what these researchers have done with social infrastructures as complex as electrical networks. In light of Haldane’s comments, the scientists wondered if the expansion of these networks should continue or if, on the contrary, there is an optimum adequate size for their correct functioning. The answer is yes, according to the results of the power network model that these UC3M scientists, in collaboration with researchers at the University of Alaska Fairbanks and Iowa State University (both in the USA), used in the study, which was recently published in the journal Chaos.

The Race for Ethanol
|Steve Baragona ||May 11th 2014|
When U.S. drivers fill their tanks with ethanol, they are essentially buying fermented corn grown by American farmers.
A 2007 law requires gasoline makers to add increasing amounts of the biofuel to the U.S. fuel supply. With petroleum-based fuels contributing to climate change, advocates have backed plant-based biofuels as a greener source of energy. However, rising costs and competition for resources have led some regulators to propose a reduction in the ethanol requirement.
The 2007 law sparked an ethanol boom that has boosted rural economies. Another benefit, according to Bob Dinneen, head of the ethanol trade group the Renewable Fuels Association, is that corn absorbs the greenhouse gas carbon dioxide as it grows. “We are produced from agricultural crops and residues that are taking carbon out of the air, something petroleum can’t claim,” Dinneen said.
But ethanol has a flock of critics. Poultry and other meat producers say their animals are now competing with ethanol for the corn supply. That has raised corn prices and costs for raising livestock. Read more ..
The Battle for Ukraine
|Charles Recknagel||May 8th 2014|
The European Union gets about one-third of its natural gas from Russia, and about half of that gas arrives in Europe via pipelines passing through Ukraine. Moscow is threatening to cut off natural-gas deliveries to Ukraine unless Kyiv promptly pays its outstanding bills. And that means the EU could potentially be caught in the cross fire.
Here are five things to know about the situation.
Why Should The EU Worry
One reason is empty natural-gas storage facilities in western Ukraine. Summer is when Ukraine usually fills its giant storage facilities with Russian gas to provide for peak usage periods during the winter, when the real-time gas flow from Russia is not enough to meet local demand.
But there is no guarantee the tanks will be filled this summer as Kyiv and Moscow quarrel over gas prices. That is troubling because if Ukraine's winter tanks are not full, there is a danger it might compensate for winter shortages by siphoning off Russian natural gas intended for Europe. Read more ..
The Race for Clean Electricity
|Jeannie Kever||May 7th 2014|
University of Houston
University of Houston physicists have discovered a new thermoelectric material offering high performance at temperatures ranging from room temperature up to 300 degrees Celsius, or about 573 degrees Fahrenheit.
"This new material is better than the traditional material, Bismuth telluride, and can be used for waste heat conversion into electricity much more efficiently," said Zhifeng Ren, M.D. Anderson Chair professor of physics at UH.
Ren, who is also principal investigator at the Texas Center for Superconductivity at UH, said the work could be important for clean energy research and commercialization at temperatures of about 300 degrees Celsius.
Bismuth telluride has been the standard thermoelectric material since the 1950s and is used primarily for cooling, although it can also be used at temperatures up to 250 C, or 482 F, for power generation, with limited efficiency. Read more ..

Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using "bench" chemistry -- no fancy equipment or hazardous materials.
"This is a breakthrough in taking the lead out of a very promising type of solar cell, called a perovskite," said Mercouri G. Kanatzidis, an inorganic chemist with expertise in dealing with tin. "Tin is a very viable material, and we have shown the material does work as an efficient solar cell."
Kanatzidis, who led the research, is the Charles E. and Emma H. Morrison Professor of Chemistry in the Weinberg College of Arts and Sciences.
The new solar cell uses a structure called a perovskite but with tin instead of lead as the light-absorbing material. Lead perovskite has achieved 15 percent efficiency, and tin perovskite should be able to match -- and possibly surpass -- that. Perovskite solar cells are being touted as the "next big thing in photovoltaics" and have reenergized the field. Read more ..
The Race for EVs
Ironically one potential wrinkle in Tesla’s $5 billion Gigafactory lithium-ion battery strategic plans could turn out to be an environmental one.
Saving the environment of the planet is supposed to be one of the key reasons why people should be switching to battery-powered electric vehicles in the future. The argument goes that battery-powered EVs cause less pollution than their petrol-powered rivals but as western societys more environmentally conscious citizens consider whether to switch to so-called eco-friendly EVs we now realize that damaging forms of air and water pollution are blighting large tracts of China. Unfortunately a contributory factor in the Chinese pollution syndrome is caused by a vital constituent of EV batteries namely graphite. Read more ..
The Race for Natural Gas
Russia's confrontation with the West over the growing unrest in eastern Ukraine could lead to another energy crisis in the European countries that are dependent on Russian energy. Europe gets about one-third of its gas supplies from Russia, and about half of it is dispatched through Ukraine. Europeans are increasingly looking into alternative sources of energy to reduce their reliance on Russia. Meanwhile, the EU is mediating a deal between Russia and Ukraine that would secure a steady gas supply for next winter.
The Ukrainian military effort to regain cities under pro-Russian rebel control has not gone as well as the government in Kyiv expected. Acting President Oleksander Turchynov said the military has had to act with restraint in order to spare civilians.
"I would like to underline that the operation did not progress as quickly as hoped for, and was complicated by the fact that terrorist bases are situated in heavily populated cities, and that they were hiding behind citizens, hiding behind hostages and firing from apartment blocks," he said.

The Coal Problem
|Timothy Cama||April 30th 2014|
The Labor Department announced Wednesday that it is finalizing a long-delayed rule to cut the amount of coal dust to which miners can be exposed.
The Mine Safety and Health Administration (MSHA) rule will reduce coal-dust exposure limits by a quarter for underground mines and improve requirements for air sampling and monitoring in an attempt to reduce respiratory disease. It will take advantage of new technology to provide real-time monitoring of dust levels, which would allow miners and supervisors to avoid periods of high coal dust.
“Today we advance a very basic principle: you shouldn't have to sacrifice your life for your livelihood,” Labor Secretary Thomas Perez said in a statement. “But that's been the fate of more than 76,000 miners who have died at least in part because of black lung since 1968.”
In a notice scheduled to be published May 1 in the Federal Register, MSHA said chronic coal-dust exposure causes lung diseases such as coal workers’ pneumoconiosis, emphysema, silicosis and chronic bronchitis, together known as black lung. “These diseases are debilitating and can result in disability and premature death,” the safety group said.

Iran on Edge
|Frud Bezhan||April 26th 2014|
Iranians have gone online to vent their frustration at the government after it slashed state subsidies on gasoline, a move that has seen the price at the pump skyrocket by up to 75 percent.
The dramatic price hikes, which took effect at midnight on April 25, are expected to test President Hassan Rohani’s support among a population fed up with stubborn inflation, rising costs, and high unemployment.
Observers see it as a risky move. There were riots at some gas stations in 2007 when fuel rationing was imposed for the first time. While there have been reports of no violence or protests after the latest price hikes, police have been put on alert. Iranians on social networking sites have criticized the government’s move, part of a second phase of government plans to remove energy subsidies and revive the country’s flatlining, sanctions-hit economy.

India on Edge
|Mandira Banerjee||April 24th 2014|
About a third of India's electricity is lost each year. It just never gets billed. Some is stolen or disappears because of technical problems. It's enough power to light up all of Italy for a year. The problem gets especially bad during elections when electricity is used to win votes, a new University of Michigan study shows. The research focused on state elections in Uttar Pradesh—the country's largest state—and found that power losses increased by three percentage points just before the polls.
"Our paper offers a political explanation on electricity loss and why it persists in plain sight," said Brian Min, assistant professor of political science. "In short, elected political leaders benefit at the polls when their constituents receive more electricity." The study highlights two big challenges in the world's most populous democracy: rampant corruption and wobbly infrastructure. Both are frequently blamed for the recent slowdown in India's economy—a major issue in the general elections that wrap up May 12. Read more ..

A changing climate is increasing the accessibility of U.S. Arctic waters to commercial activities such as shipping, oil and gas development, and tourism, raising concern about the risk of oil spills. A new report from the National Research Council says that a full suite of proven oil response tools is needed to address potential oil spills in U.S. Arctic waters, but not all of them are readily available. While much is known about both oil behavior and response technologies in ice-covered environments, there are areas where additional research would enable more informed decisions about the most effective response strategies for different Arctic spill situations, the report adds.
The Arctic poses several challenges to oil spill response, including extreme weather and environmental settings, limited operations and communications infrastructure, a vast geographic area, and vulnerable species, ecosystems, and cultures. The report finds that there is a need to validate current and emerging oil spill response technologies under these real-world conditions, and recommends that carefully controlled field experiments that release oil in the U.S. Arctic be conducted as part of a long-term, collaborative Arctic oil spill research and development program that spans local, state, and federal levels.

Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they’re still in the ground.
The nanoreporter is based on nanometer-sized carbon material developed by a consortium of Rice labs led by chemist James Tour and is the subject of a new paper published this month in the American Chemical Society journal ACS Applied Materials and Interfaces.
Limited exposure to hydrogen sulfide causes sore throats, shortness of breath and dizziness, according to the researchers. The human nose quickly becomes desensitized to hydrogen sulfide, leading to an inability to detect higher concentrations. That can be fatal, they said.
On the flip side, hydrogen sulfide is also a biologically important signaling molecule in processes that include pain and inflammation. Tour said chemists have synthesized fluorescent probes to detect it in the body. The Rice team capitalized on that work by using the probes to create downhole detectors for oil fields. Read more ..
The Race for Bio-Fuel
|John Landis||April 21st 2014|
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions.
Corn stover -- the stalks, leaves and cobs in cornfields after harvest -- has been considered a ready resource for cellulosic ethanol production. The U.S. Department of Energy has provided more than $1 billion in federal funds to support research to develop cellulosic biofuels, including ethanol made from corn stover. While the cellulosic biofuel production process has yet to be extensively commercialized, several private companies are developing specialized biorefineries capable of converting tough corn fibers into fuel.

The Obama administration on Friday extended its review period for the Keystone XL pipeline, potentially delaying a decision on the project until after the midterm elections.
With just 14 days left in a 90-day review, State Department officials said they were stopping the clock due to litigation in Nebraska over the pipeline's proposed route.
State declined to provide a specific timeline for restarting the review process, effectively putting the project in limbo.
The delay could disarm a political land-mine for President Obama, who had found himself caught between rival factions of his Democratic base.
While Keystone has significant support from industry groups and some labor unions, it is staunchly opposed by environmentalists, who say its approval would be a betrayal and a stain on the president's climate change legacy.
Those dynamics made the Keystone decision a lose-lose situation for the White House, with any decision bound to alienate core supporters that Democrats need to turn out this fall.
The pipeline is a project of the developer TransCanada and would carry oil sands from Canada to Gulf Coast refineries.
A senior State Department official said that while the agency is essentially freezing the review process to wait for more information on the situation in Nebraska, it may start the clock back up before the state's supreme court makes a ruling. Read more ..
The Coal Problem

Environmental activists in Thailand are protesting plans to reopen an 800-megawatt coal plant in a coastal region, Krabi, that is popular with eco-tourists. The controversy pits Thailand’s growing energy needs against its image as a seaside paradise.
Along the southwestern coast, tourism is big business, worth more than $40 million a year.
Despite rapid development, Krabi, a coastal province, is still recognized as a green tourism zone and its wetlands are included on an international conservation list.
To meet rising demand for electricity, authorities are planning to restart a local power plant, which will bring ships hauling coal near parks and beaches popular with tourists. Near the power plant’s location in Krabi town, fisherman Manit Bootpheaw remembers the health problems from the 90's when it was last active. Read more ..

Google has recently celebrated 15 years since its launch. While still in its teens, Google has dramatically changed the way most people see and use the internet and has become an integral part of daily life. In similar ways, new technologies which were the reserve of Sci-fi less than ten years ago are currently being developed for both consumer markets and the professional world. What Google has done for the internet, wearable and implantable technologies may well do for medicine.
According to a piece of research published by IMS in 2012, the wearable technology market is expected to reach $6 billion by 2016. IMS defines wearable technologies as products that are worn on the user's body for an extended period of time, contain advanced circuitry, as well as wireless connectivity, that can process data.
The medical field is one of the leading professional sectors when it comes to investments in research and product design. Portable devices such as nebulisers or infusion pumps and wearable devices like endoscopy recorders or blood pressure and glucose monitors are only a few of the technologies which are now available to the public.

What might the oil- and gas-rich Eagle Ford Shale region of South Texas look like in 2018?
A newly released but largely unnoticed study commissioned by the state of Texas makes some striking projections:
***The number of wells drilled in the 20,000-square-mile region could quadruple, from about 8,000 today to 32,000.
***Oil production could leap from 363 million barrels per year to as much as 761 million.
***Airborne releases of volatile organic compounds (VOCs) could increase 281 percent during the peak ozone season compared to 2012 emissions. VOCs, commonly found at oil and gas production sites, can cause respiratory and neurological problems. Some, like benzene, can cause cancer.
***Nitrogen oxides — which react with VOCs in sunlight to create ground-level ozone, the main component of smog — could increase 69 percent during the peak ozone season. Read more ..
Ukraine on Edge
|Martin Barillas||April 13th 2014|
Ukraine's acting Interior Minister Arsen Avakov said in a Facebook message on April 13 that Ukrainian security forces have launched an "antiterrorist operation" in the eastern city of Slovyansk where on the previous day separatists, aligned with Russia, seized the city hall and Ukrainian Security Service headquarters. Avakov characterized the attack as an “act of aggression” by Russia.
Avakov wrote that "forces from all the security units of the country have been brought in." Slovyansk is one of several Ukrainian cities where pro-Russian militants bearing automatic weapons on April 12 stormed police stations. Military helicopters were spotted flying over Slovyansk early on April 13.
With covered faces, armed men wearing mismatched military clothing and gear have seized government buildings in Slovyansk, which is only 90 kilometres from the Russian border. Hundreds of pistols have been seized from police headquarters in Slovyansk and presumably now being distributed to Russian sympathizers in the region. Armed pro-Russian militants have spread out in Slovyansk. Read more ..

A top building trades union is launching a midterm-election assault on House Democrats who oppose construction of the Keystone XL oil pipeline.
A letter distributed Friday by the Laborers' International Union of North America (LIUNA) to the districts of 27 House Democrats calls for union members to make sure their representative "feels the power and the fury of LIUNA this November."
Their crime: signing a letter to Secretary of State John Kerry last month urging him to reject Keystone, which would carry oil sands from Canada to Gulf Coast refineries.
"Your member of Congress is trying to destroy job opportunities for our LIUNA brothers and sisters," said the letter signed by Terry O'Sullivan, the general president of LIUNA. Read more ..

|Paul Buckley||April 11th 2014|
Panasonic Corporation is claiming to be the first organization in the world to break through the 25% conversion efficiency barrier for practical size solar cells at the research level. The company claims it has achieved a conversion efficiency of 25.6% for a solar cell area of 143.7 cm with the company's HIT solar cells.
The previous record for the conversion efficiency of crystalline silicon-based solar cells of a practical size (100 cm and over) was 24.7%, which was announced by Panasonic in February 2013 (cell area: 101.8 cm). The new record is also an improvement of 0.6 points compared with the previous record for small area crystalline silicon-based solar cells (cell area: 4 cm) of 25.0%.
Panasonic claimed the achievement of the record was made possible by further development of the company's proprietary heterojunction technology to realize the high conversion efficiency and superior high temperature properties of the company's HIT solar cells as well as adopting a back-contact solar cell structure, with the electrodes on the back of the solar cell, which allows the more efficient utilization of sunlight.

Privately owned Israeli startup, StoreDot Ltd has unveiled a ground-breaking battery capable of charging your smartphone and other devices in just 30 seconds.
At Microsoft’s Think Next symposium in Tel Aviv, StoreDot demonstrated the prototype of its ultra-fast-charge battery for the first time. StoreDot specializes in technology that is inspired by natural processes, cost-effective and environmentally-friendly. The company produces “nanodots” derived from bio-organic material that, due to their size, have both increased electrode capacitance and electrolyte performance, resulting in batteries that can be fully charged in minutes rather than hours.
These multifunctional nanodots are chemically synthesized bio-organic peptide molecules that change the rules of mobile device capabilities. These nanocrystals are made from peptides, short chains of amino acids, the building blocks of proteins. Read more ..
The Race for AltFuel
|Layne Cameron||April 9th 2014|
What began 20 years ago as an innovation to improve paper industry processes and dairy forage digestibility may now open the door to a much more energy- and cost-efficient way to convert biomass into fuel.
The research, which appears in the current issue of Science, focuses on enhancing poplar trees so they can break down more easily, improving their viability as a biofuel. The long-term efforts and teamwork involved to find this solution can be described as a rare, top-down approach to engineering plants for digestibility, said Curtis Wilkerson, Michigan State University plant biologist and the lead author.
“By designing poplars for deconstruction, we can improve the degradability of a very useful biomass product,” said Wilkerson, Great Lakes Bioenergy Research Center scientist. “Poplars are dense, easy to store and they flourish on marginal lands not suitable for food crops, making them a non-competing and sustainable source of biofuel.” Read more ..

Stanford University scientists have found a new, highly efficient way to produce liquid ethanol from carbon monoxide gas. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists. Their results are published in the April 9 advanced online edition of the journal Nature.
"We have discovered the first metal catalyst that can produce appreciable amounts of ethanol from carbon monoxide at room temperature and pressure – a notoriously difficult electrochemical reaction," said Matthew Kanan, an assistant professor of chemistry at Stanford and coauthor of the Nature study.
Most ethanol today is produced at high-temperature fermentation facilities that chemically convert corn, sugarcane and other plants into liquid fuel. But growing crops for biofuel requires thousands of acres of land and vast quantities of fertilizer and water. In some parts of the United States, it takes more than 800 gallons of water to grow a bushel of corn, which, in turn, yields about 3 gallons of ethanol. Read more ..
The Power Grid Problem

Some 90 years ago, British polymath J.B.S. Haldane proposed that for every animal there is an optimal size -- one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing or hibernating. Today, three researchers are asking whether there is a "right" size for another type of huge beast: the U.S. power grid.
David Newman, a physicist at the University of Alaska, believes that smaller grids would reduce the likelihood of severe outages, such as the 2003 Northeast blackout that cut power to 50 million people in the United States and Canada for up to two days.
Newman and co-authors Benjamin Carreras, of BACV Solutions in Oak Ridge, Tenn., and Ian Dobson of Iowa State University make their case in the journal Chaos, which is produced by AIP Publishing. Their investigation began 20 years ago, when Newman and Carreras were studying why stable fusion plasmas turned unstable so quickly. They modeled the problem by comparing the plasma to a sandpile.

The Race for Solar

South Africa is the African continent's most advanced nation -- yet an estimated 3 million of its residents live without electricity. The government says it's working to improve its infrastructure to reach those people -- many of them in remote areas -- but it is simultaneously struggling to provide enough power for its growing urban population. In a remote South African village - actually called "armpit" in the local language - electricity is available for the first time in 2014.
Wilson Tshitande has lived in the remote village of Gwakwani for as long as he can remember. He boasts that he knows every stick, every rock and every plant in this settlement of less than 100 people. But one thing the 70-year-old never thought he would see has finally come to this village in South Africa's largely rural Limpopo province: electricity.
In the local Venda language, the name "Gwakwani" literally means "armpit." It's so named because it's wedged under the nearest river and other important landmarks. But perhaps, residents say, the village's modesty has also led to their being overlooked in their request for electricity. Read more ..
The Automotive Edge
|Christoph Hammerschmidt||April 7th 2014|
The average driver spends about an entire week per year caught up in traffic congestions. Increasingly the vehicles are equipped with electronic systems aiming at keeping the traffic flowing or finding alternative routes. Cooperative systems are better suited for this task, finds Frost & Sullivan.
Cooperative systems include vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications; both applications combined are called vehicle-to-x (V2X) communications. One of the core elements of these systems is the cooperative wireless ad-hoc network established between other vehicles and infrastructure, based on a modified version of the WiFi standard which itself has been baptized Dedicated Short-Range Communications (DSRC). Current planning provides for system enhancements based on infrared communications and global satellite navigation systems (GNSS) as well as new solutions based mobile telecommunications networks, in particular LTE.

Poor judgement and an effort to avoid millions in taxes caused Royal Dutch Shell's Arctic rig to run aground in 2012, according to a new U.S. Coast Guard report.
The Coast Guard blamed Shell's "poor assessment and management of risks" associated with towing a heavy-duty drilling rig across Alaskan waters during winter.
The single most significant factor contributing to the grounding of the Kulluk oil drilling rig, the report said, was the decision to move the vessel "during the winter in the unique and challenging operating environment of Alaska." Shell spent billions of dollars in oil and gas exploration and drilling efforts across Alaska's Beaufort and Chukchi seas in the Arctic ocean.
The report, released Thursday afternoon, also states Shell rushed to move its rig to avoid state taxes in Alaska, which further led to complications. When the rig lost control a containment dome used to cap spills suffered damage, which prompted the Interior Department to review Shell's operations. Read more ..
Ukraine on Edge

Ukraine's Prime Minister, Arseniy Yatsenyuk, has accused Russia of "economic aggression" and threatened to sue Russia over recent price hikes for natural-gas supplies. "Russia was unable to seize Ukraine by means of military aggression. Now they are implementing plans to seize Ukraine through economic aggression," Yatsenyuk told a government meeting on April 5. "Political pressure is unacceptable," he continued. "We do not accept the price of $500."
Yatsenyuk's comments come after Russia twice this last week raised the price of natural-gas for Ukraine, taking the cost for Ukraine from $285.5 per 1,000 cubic meters at the start of this last week to $485.5 by the end of the week. Read more ..
