Eco-Friendly Renewable Battery gets Solar Boost with Israeli Technology

August 26th 2011

Energy Topics - Solar panels

Batteries are everywhere - not just in iPods and smart phones. They power billions of devices, but they are expensive and aren't always easy to change. Israeli startup Sol Chip has a cure for the battery blues - an eco-friendly renewable battery power technology that integrates photovoltaic energy sources (PV) with low-power electronic devices (VLSI).

For a good example of Sol Chip's breakthrough, check out today's large dairy farms. Low-power radio frequency identification (RFID) tags are used to keep track of the herd's location, milk production and registration details while protecting the cows against disease and theft. When the tags eventually run out of power, replacing their batteries isn't practical since the tags have to remain sealed against humidity and rain. So farmers end up having to attach a new tag at great trouble and expense. Read more ..

Disaster - Gulf Oil Spill Sat Image 2010-05-24

One year after launching a program to compensate the victims of the massive Gulf of Mexico oil spill, administrator Kenneth Feinberg said Tuesday the process has “largely succeeded,” while acknowledging some initial missteps.

President Obama tapped Feinberg last year to head up the claims process. Feinberg established the Gulf Coast Claims Facility (GCCF) with the aim of doling out the $20 billion BP set aside to compensate victims of the spill and clean up the region.

“I think overall we’ve largely succeeded in getting money out to eligible claimants,” Feinberg said.

Feinberg has come under fire from Gulf Coast lawmakers and others, who argue that he has not moved quickly enough to compensate the victims of the spill. At the same time, BP has argued that the GCCF’s claims formula is overly generous. Read more ..

East Coast Earthquake Shakes up Debate over Nuclear Power

August 25th 2011

Energy Topics - Nukuler plants in Amerika

Virginia's largest earthquake in more than a century shook the East Coast on August 23 and is likely to revive a long-standing debate about the safety of the country's nuclear power plants.

The 5.8 magnitude earthquake caused the shutdown of two nuclear reactors at the North Anna Power Station in Louisa County, Va. The plant, which is located less than 20 miles from the epicenter of the quake, lost offsite power and was running its cooling systems on diesel generators on August 23. Dominion said it was able to restore offsite power to the reactors late evening August 23.

While there were no reports of damage at the North Anna reactors and plant operator Dominion said the cooling systems were working properly, nuclear opponents quickly pounced on the incident August 23.

They say the incident shows that U.S. nuclear reactors are vulnerable to major natural disasters and the Nuclear Regulatory Commission should move quickly to implement a series of sweeping regulatory changes recommended by a federal task force last month. Read more ..

In the world of solar energy, organic photovoltaic solar cells have a wide range of potential applications, but they are still considered an upstart. While these carbon-based cells, which use organic polymers or small molecules as semiconductors, are much thinner and less expensive to produce than conventional solar cells made with inorganic silicon wafers, they still lag behind in their ability to efficiently convert sunlight into electricity.

Now, UCLA researchers and their colleagues from China and Japan have shown that by incorporating gold nanoparticles into these organic photovoltaics — taking advantage of the plasmonic effect, by which metal helps to enhance the absorption of sunlight — they can significantly improve the cells' power conversion.

Photovoltaics Energy-Conversion Powered by Heat

August 22nd 2011

Science - Iron man

A new photovoltaic energy-conversion system developed at the Massachusetts Institute of Technology can be powered solely by heat, generating electricity with no sunlight at all. While the principle involved is not new, a novel way of engineering the surface of a material to convert heat into precisely tuned wavelengths of light — selected to match the wavelengths that photovoltaic cells can best convert to electricity — makes the new system much more efficient than previous versions.

The key to this fine-tuned light emission lies in a material with billions of nanoscale pits etched on its surface. When the material absorbs heat, whether from the sun, a hydrocarbon fuel, a decaying radioisotope or any other source, the pitted surface radiates energy primarily at these carefully chosen wavelengths.

Polymer LEDs that Stretch Like Rubber

August 22nd 2011

Energy Topics - electron microscope

Today's conventional inorganic electronic devices are brittle, and while they have a certain flexibility achieved using ultrathin layers of inorganic materials, these devices are either flexible, meaning they can be bent, or they are stretchable, containing a discrete LED chip interconnected with stretchable electrodes.

But they lack "intrinsic stretchabilty," in which every part of the device is stretchable. Now, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have demonstrated for the first time an intrinsically stretchable polymer light-emitting device.

They developed a simple process to fabricate the transparent devices using single-walled carbon nanotube polymer composite electrodes. The interpenetrating networks of nanotubes and the polymer matrix in the surface layer of the composites lead to low sheet resistance, high transparency, high compliance and low surface roughness.

Political Common Ground on Peak Oil and Public Health

August 10th 2011

Energy Topics - Arab Oil Derick

Peak petroleum—the point at which the maximum rate of global oil extraction is reached, after which the rate of production begins to decline—is a hot topic in scientific and energy circles. When will it occur? What will the impact be? While geologists and economists debate the specifics, American University School of Communication professor Matthew Nisbet believes peak petroleum and the associated risks to public health may provide an opportunity to bring conservatives and liberals together in the move toward alternative forms of energy.

“Somewhat surprisingly, conservatives are more likely to associate a major spike in oil prices with a strong threat to public health,” said Nisbet—an expert in the field of climate and energy communication. “This could present a gateway to engagement with conservatives on energy policy.” Read more ..

Water/Methanol Hybrid Energy System Boosts Rooftop Solar Power

August 10th 2011

Science - hydrogen system

While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays.

Instead of systems based on standard solar panels, Duke engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen much more efficiently than current technology without significant impurities. The resulting hydrogen can be stored and used on demand in fuel cells.

For his analysis, Hotz compared the hybrid system to three different technologies in terms of their exergetic performance. Exergy is a way of describing how much of a given quantity of energy can theoretically be converted to useful work. Read more ..

Inflatable Wind Turbines Proving to be an Affordable Energy Solution

August 5th 2011

Energy / Environment - Inflatable Wind Turbine

Inflatable wind turbines are now lighter and cheaper than heavy conventional ones. Following a number of  Israeli clean technology companies being winners in the General Electric Company’s Green Innovation Marathon, GE has announced plans to establish a “Green Tech Shop” in Haifa in which a number of renewable energy and other green technology projects will be developed under the giant American electronics company’s sponsorship. One of these green companies, Winflex LTD, is set on proving that harnessing energy from the wind does not have to involve the use of  large cumbersome wind turbines, such as the wind turbines now churning away on the Golan Heights.

Winflex wind rotor

What is unique about Winflex’s inflatable wind turbines is that they are made out of “light, flexible and inexpensive cloth sheets made out of composite materials.” The result are light weight portable wind turbines that can be installed virtually anywhere – even on home rooftops – and result in a much shorter return on equipment investment than conventional wind turbines. By reducing costs and erection time of equipment, it reduces need for government subsidies, according to Winflex’s Chief Technical Officer, Dr. Vladimir Kliatzkin.

Using inflatable, easily installed wind turbines is a novel idea, especially compared to those giant whirling wind turbines are now becoming commonplace in many western European countries, such as Spain, France, Belgium, Denmark, and Holland. Winflex’s designs uses a much lighter rotor around which the turbine blades revolve like sails from a sailing vessel. Read more ..

The White House budget office raised flags about the first energy loan guarantee awarded under the Obama administration, adding another layer of questions to the taxpayer backed financing now at the center of a House investigation.

In 2009, as the Department of Energy pushed to close the $535 million loan guarantee to California solar panel maker Solyndra Inc., the Office of Management and Budget concluded the financing was a greater risk to taxpayers than did DOE. That higher risk rating, in turn, forced the government to set aside more money in case the company defaults on payments.

The Department of Energy pressed ahead, formally approving the deal in September 2009 while portraying the Solyndra loan guarantee as a symbol of President Obama’s quest to spread green energy projects with government backing. Read more ..

Photovoltaic Inverter shipments to grow to 27-GW by 2015 due to Grid Integration

July 27th 2011

Energy / Environment - solar panels and flowers

‘Smart’ photovoltaic inverter (PV) shipments are forecast to grow to 27 GW in 2015, accounting for almost 60 percent of the market compared to just 20 percent in 2010 according to the latest report from market analyst, IMS Research. The growth is being driven by utility concerns over grid imbalances, the growing proportion of photovoltaic inverters connected to the grid, as well as the need for energy storage to take advantage of self-consumption tariffs and further incorporate photovoltaic inverters into the ‘smart grid.’

According to the new IMS Research report entitled “The World Market for PV Inverters,” features such as reactive power, smart grid interaction and energy storage are transforming inverters from a simple power conversion unit into an essential component of grid infrastructure and will radically change the PV inverter market over the next five years. Tom Haddon a PV Research Analyst at IMS Research explained: “Utilities, especially in Europe, are increasingly pushing for inverters to assist in grid stabilization and conform to stricter technical requirements.”

Because of this, IMS Research forecasts that smart inverters will account for 80% of the EMEA market in 2015. Haddon commented: “Despite this, most inverter shipments will still not be “fully smart” and will only have reactive power capabilities, rather than full smart grid interaction or energy storage.” Read more ..

Syrian Issues - Syrian oil tanks

By targeting Syria's energy sector, the United States can hit President Bashar al-Assad where it really hurts -- his pocketbook.

Four months into Syria's uprising, the violence wracking the country is bad and getting worse. The restive city of Homs witnessed sectarian clashes over the weekend that reportedly left dozens dead, while forces loyal to Syrian President Bashar al-Assad converged on the eastern town of Abu Kamal. As the Assad regime's iron-fist-in-a-velvet-glove approach to the uprising continues to fail, all eyes are focused on the Aug. 1 start of the Muslim holy month of Ramadan, when the minority Alawite regime's killing of predominately Sunni protesters could transform the uprising into a sectarian bloodbath.

This bloodshed, which is tragic in its own right, is also causing the sputtering Syrian economy to grind to a halt. Such a development would be particularly dangerous for Assad, as it could cause the business elite in the commercial hubs of Damascus and Aleppo to finally break ties with the regime and join ranks with the opposition.

On July 12, for the second time in a week, the crucial gas pipeline leading to Israel and Jordan from Egypt was attacked. Saboteurs blew up the Egyptian gas pipeline distribution station in northern Sinai, sending plumes of smoke and flame hundreds of feet into the air. The explosion was the fourth attack this year on pipelines in Sinai that supply gas to Israel and Jordan. With roiling unrest in its eastern neighbour, Israel's important economic ties to Egypt are deteriorating, said Israeli National Infrastructures Minister Uzi Landau in a radio interview. "The most important economic connection between Israel and Egypt is eroding," Landau said. "Electricity disruptions are not expected since we have other energy reserves, however it will be more expensive." He added, "The price will increase by about 20 percent due to the use of gasoline and diesel, but my job is to maintain the supply of electricity to the Israeli economy."

Landau continued, "Israel was ready to allow Egypt to deploy more forces in Sinai to secure the pipeline, even at the beginning of the Egyptian uprising, in opposition to the peace agreement," he explained. "But I recommend against interfering since our neighboring country's situation is not simple. Israel needs to rely on herself and the Tamar reserves can supply [gas] needs for the next 25 years."

Paved Surfaces and Urban Development Alters Weather Patterns

June 14th 2011

Transportation Topics - Man hole cover

New research focusing on the Houston, Texas, area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. The international study, led by the National Center for Atmospheric Research (NCAR), could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas.

The reason: the proliferation of strip malls, subdivisions and other paved areas may interfere with breezes needed to clear away smog and other pollution. The researchers combined extensive atmospheric measurements with computer simulations to examine the impact of pavement on breezes in Houston.

They found that, because pavement soaks up heat and keeps land areas relatively warm overnight, the contrast between land and sea temperatures is reduced during the summer. This in turn causes a reduction in nighttime winds that would otherwise blow pollutants out to sea. Read more ..

Tiny Israel, long dependent on outsiders for its energy needs, is poised to become a major exporter of oil. That's according to Lawrence Solomon, writing in the Financial Post.

One of the largest deposits – 250 billion barrels of oil in Israel’s Shfela basin, comparable to Saudi Arabia’s entire reserves of 260 billion barrels of oil – has until now been unexploited, partly because the technology required has been expensive, mostly because the multinational oil companies that have the technology fear offending Muslims.

“None of the major oil companies are willing to do business in Israel because they don’t want to be cut off from the Mideast supply of oil,” explains Howard Jonas, CEO of IDT, the U.S. company that owns the Shfela concession through its subsidiary, Israel Energy Initiatives.

In February, after seeing fellow Sunni Muslim regimes destabilizing throughout the Middle East, Saudi King Abdullah rushed back from New York, where he was recovering from a back injury, to the kingdom to stave off any potential spillover. After all, if Egyptian President Hosni Mubarak had been ousted, anyone could be. In an attempt to pacify its subjects, the House of Saud announced a “stimulus package” that included an increase in subsidies, a 15 percent salary raise to all government employees, and housing benefits to military and religious groups in exchange for support of his ban on protests.

In total, $133 billion was committed—equivalent to 86 percent of the Saudi regime’s $154 billion 2011 budget approved before the disturbances. (For the sake of comparison, the $787 billion economic stimulus plan implemented by the Obama administration constituted 25 percent of the U.S. federal budget.)

Saudi Arabia is not the only country where money was used to pacify disgruntled masses.

Kuwait’s Emir Sheikh Ahmad Al Sabah increased his country’s budget liabilities by nearly 10 percent, committing to provide each of the country’s 1.12 million citizens some $3,572. In addition, he offered citizens free essential foodstuffs for one year, at the cost of $1 billion. Read more ..

The Pacific Northwest has the diverse feedstocks, fuel-delivery infrastructure and political will needed to create a viable biofuels industry capable of reducing greenhouse gases and meeting the future fuel demands of the aviation industry. Creating an aviation biofuels industry, however, will depend upon securing early government policy support to prioritize the aviation industry in U.S. biofuel development. That's the conclusion announced in a 10-month study by Sustainable Aviation Fuels Northwest, the nation's first regional stakeholder effort to explore the feasibility, challenges and opportunities for creating an aviation biofuels industry in the Pacific Northwest. Boeing, Alaska Airlines, Portland International Airport, Seattle-Tacoma International Airport, Spokane International Airport and Washington State University partnered in a strategic initiative to identify the potential pathways and actions necessary to make safe, sustainable aviation biofuel commercially available to airline operators in the area.

The New Silk Road: China’s Energy Strategy in the Greater Middle East—The Four Seas Strategy

May 28th 2011

China Topics - China Energy String of Pearls

As Beijing embarks on its “look west” Silk Road development strategy, Syria’s “look east” policy aims to meet China at the Caspian Sea. Since 2009, Syrian president Bashar al-Asad has promoted his Four Seas strategy to transform his country into a trade hub in the regions bordering the Black Sea, Mediterranean Sea, Persian Gulf/Arabian Sea, and the Caspian. Damascus has therefore been aligning with key countries that lie on these shores, namely Turkey, Iran, and Azerbaijan. According to one analyst, Syria’s economic relationship with Ankara lies at the center of this strategy, particularly the two countries’ efforts to connect their oil and gas infrastructure with the region’s expanding pipeline networks. With Turkey emerging as Syria’s most significant investor and trade partner and Iran remaining the guarantor of Syria’s security, the Ankara-Damascus-Tehran triangle has become the nucleus of an approach that aims to include Iraq and the Caucasus in a geographical continuum linking the Four Seas.
