energy storage> Enhanced electrical energy storage from a new porus three-dimensional carbon that can be used as a greatly enhanced supercapacitor

Enhanced electrical energy storage may result from professor's research

Researchers at The University of Texas at Austin's Cockrell School of Engineering have created a new porous, three-dimensional carbon that can be used as a greatly enhanced supercapacitor, holding promise for energy storage in everything from energy grids and electric cars to consumer electronics.

The findings of the group, led by materials science and mechanical engineering Professor Rodney S. Ruoff, will be published May 12 by Science magazine in its online publication ScienceXpress.

The significance of the discovery by Ruoff's team, which included postdoctoral fellow Dr. Yanwu Zhu and graduate students Shanthi Murali and Meryl Stoller, is the potential it offers for enabling supercapacitors to deliver significantly more charge, opening the doors to many potential unprecedented uses for this type of electrical energy storage device.

Supercapacitors are known as the "sprinters" among electrical energy storage devices, able to deliver energy much faster and more efficiently than batteries, but usually holding much less electrical charge, while batteries are like marathon runners, delivering energy slowly, but steadily.

"We synthesized a new sponge-like carbon that has a surface area of up to 3,100 square meters per gram (two grams has a surface area roughly equivalent to that of a football field). It also has much higher electrical conductivity and, when further optimized, will be superb for thermal management as well," Ruoff said. "The processes used to make this porous carbon are readily scalable to industrial levels.

"After we realized that we had a new carbon with a highly novel structure that showed superb performance as an electrode, we knew that this direction of research — to create carbon materials that consist of a continuous three-dimensional porous network with single-atom-thick walls — was likely to yield the optimum electrode material for supercapacitors."

The University of Texas at Austin's Office of Technology Commercialization has filed a patent with the U.S. Patent Office on behalf of the inventors.

"Rod and his team define what we mean when we talk about innovation to address grand challenges," said Gregory L. Fenves, dean of the Cockrell School of Engineering. "This team of students, researchers and faculty has discovered a way to improve the efficiency of supercapacitor energy storage."

Ruoff's research team of about 40 people collaborated with faculty and students from The University of Texas at Dallas, scientific staff at Brookhaven National Laboratory in New York and staff members at QuantaChrome Instruments in Florida.

The process used by the university team to synthesize the carbon material involved using microwaves to exfoliate graphite oxide, followed by treatment with potassium hydroxide, which created a carbon full of tiny holes — essentially a sponge that, when combined with an electrolyte, can store a giant electrical charge. The team at Brookhaven then analyzed the atomic structure of the carbon material at the nanoscale using very high resolution electron microscopes. Their observations confirmed Ruoff's hypothesis that the carbon was a new three-dimensional material having highly curved, single-atom-thick walls that form tiny pores.

A New Rare Earth Metal - Fulvalene Diruthenium - has the ability to absorb, store sunlight as heat

Researchers at Massachusetts Institute of Technology have discovered a rare earth metal, which is able to absorb sunlight and store it as pure heat until it is needed.

Rare earth metals used to be a collection of seventeen earth metals in the periodic table namely scandium, yttrium, and the fifteen lanthanides. The recently discovered rare earth element is fulvalene diruthenium which has a unique ability to act like a molecular heat battery and harness solar energy and heat from the sun and store it indefinitely by changing its conformation and being stable.

Lead author of the study, Professor Jeffrey Grossman, said that the molecular structure of the metal includes two aromatic carbon rings, attached to a transition metal. When molecule absorbs sunlight it changes state into a semi stable but perfectly safe state and by applying additional heat or some other catalyst, the heat energy that has been contained in the molecule can be released and the molecule will come back to its original state. The huge amount of heat released can be used for various purposes.

Most solar power devices in recent use can convert solar energy into electrical energy but do not act as a storage material for heat energy. When the heat is released from this rare metal either by introducing some heat or by using a catalyst a temperature of 200oC can be achieved.

 Professor Grossman said that a reversible and stable form of stored solar heat is very advantageous as it does not need any insulation and can be used where and when on demand. The major obstacle in using this advanced technology is that fulvalene diruthenium is extremely rare, making it very expensive to use. The element comes from ruthenium, which is a rare, costly hard white metal of the platinum group and only 12 tons of ruthenium are mined each year. The plus point that emerges from this very important research is that scientists are able to determine the exact mechanism and are sure that they will be able to find cheaper materials to perform the function in future.

The results of the study are published in Angewandte Chemie, a scientific journal that covers all aspects of chemistry.

Smart Self-assembling photovoltaic technology can keep repairing itself

 

[+]

This proof-of-concept version of the photoelectrochemical cell, which was used for laboratory tests, contains a photoactive solution made up of a mix of self-assembling molecules (in a glass cylinder held in place by metal clamp) with two electrodes protruding from the top, one made of platinum (the bare wire) and the other of silver (in a glass tube). (Patrick Gillooly)

MIT scientists have created a novel set of self-assembling molecules that can turn sunlight into electricity; the molecules can be repeatedly broken down and then reassembled quickly, just by adding or removing an additional solution.

In an attempt to imitate the  process of photosynthesis, Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering, and his team, supported by grants from the MIT Energy Initiative, the Eni Solar Frontiers Center at MIT and the Department of Energy, produced synthetic molecules called phospholipids that form disks; these disks provide structural support for other molecules that actually respond to light, in structures called reaction centers, which release electrons when struck by particles of light.

The disks, carrying the reaction centers, are in a solution where they attach themselves spontaneously to carbon nanotubes — wire-like hollow tubes of carbon atoms that are a few billionths of a meter thick yet stronger than steel and capable of conducting electricity a thousand times better than copper. The nanotubes hold the phospholipid disks in a uniform alignment so that the reaction centers can all be exposed to sunlight at once, and they also act as wires to collect and channel the flow of electrons knocked loose by the reactive molecules.

The system Strano’s team produced is made up of seven different compounds, including the carbon nanotubes, the phospholipids, and the proteins that make up the reaction centers, which under the right conditions spontaneously assemble themselves into a light-harvesting structure that produces an electric current. Strano says he believes this sets a record for the complexity of a self-assembling system. When a surfactant — similar in principle to the chemicals that BP has sprayed into the Gulf of Mexico to break apart oil — is added to the mix, the seven components all come apart and form a soupy solution. Then, when the researchers removed the surfactant by pushing the solution through a membrane, the compounds spontaneously assembled once again into a perfectly formed, rejuvenated photocell.

“We’re basically imitating tricks that nature has discovered over millions of years” — in particular, “reversibility, the ability to break apart and reassemble,” Strano says. The team, which included postdoctoral researcher Moon-Ho Ham and graduate student Ardemis Boghossian, came up with the system based on a theoretical analysis, but then decided to build a prototype cell to test it out. They ran the cell through repeated cycles of assembly and disassembly over a 14-hour period, with no loss of efficiency.

Strano says that in devising novel systems for generating electricity from light, researchers don’t often study how the systems change over time. For conventional silicon-based photovoltaic cells, there is little degradation, but with many new systems being developed — either for lower cost, higher efficiency, flexibility or other improved characteristics — the degradation can be very significant. “Often people see, over 60 hours, the efficiency falling to 10 percent of what you initially saw,” he says.

The individual reactions of these new molecular structures in converting sunlight are about 40 percent efficient, or about double the efficiency of today’s best solar cells. Theoretically, the efficiency of the structures could be close to 100 percent, he says. But in the initial work, the concentration of the structures in the solution was low, so the overall efficiency of the device — the amount of electricity produced for a given surface area — was very low. They are working now to find ways to greatly increase the concentration.

Smart gadgets may one day anticipate our needs

July 9, 2010 By Steve Johnson

 

Don't be surprised if one day your refrigerator nags you to lose weight, your phone blocks calls it figures you're too stressed to handle, and your wisecracking car entertains you with pun-filled one liners. Within a decade or two, researchers at Silicon Valley companies and elsewhere predict, consumer gadgets will be
functioning like hyper-attentive butlers, anticipating and fulfilling peoples' needs without having to be told. Life would not only be more convenient, it might even last longer: Devices could monitor people's health and step in when needed to help them get better.

"I think it's inevitable," said Michael Freed, an artificial intelligence specialist and program director at Menlo Park, Calif., think tank SRI International, which has been studying the concept for the military. Noting that some of these gadgets already are being developed, he added, "I expect we'll see more soon -- a trickle and then a flood.''

The technology propelling this new generation of personal assistants is a combination of sophisticated sensors and carefully tailored computer software. As envisioned, the machines would adjust their own actions to the preferences and needs of an individual, by analyzing data on the person's past actions and monitoring current behavior with cameras, audio recorders, and other sensors.

Santa Clara, Calif., chipmaker Intel, which has been studying the technology for several years, believes that one day soon the gadgets will have the ability to read their owner's emotions.

While some experts have proposed that face and voice recognition gear be used to detect a person's disposition, Intel has been experimenting with heart monitors and galvanic skin-response sensors. A study it did last year envisioned the gadgets detecting mood swings "while people are driving, singing, chatting with friends, attending a boring meeting and even while going to the dentist."

Others expect household appliances eventually will be designed with human-like personalities. In a study this year that was partly financed by Nissan, researchers at Japan's Hokkaido University experimented with cheery-sounding devices that they imagined one day could serve as "artificial companions for elderly and lonely people" or as pun-spouting car navigation equipment that could "entertain drivers by talking and
possibly by joking." Although some gadgets already make assumptions about what people want, such as word processing software that automatically corrects grammar, the devices contemplated by Intel, HP and other companies would be capable of much more sophisticated judgments about a broader array of human needs. That's a complex task -- so difficult that some experts are skeptical the technology will be ready in the near future.

"My guess is that we will get there in time, but it's a little further off than the most ambitious nnouncements from a lot of companies have indicated," said Bob Sloan, who heads the computer science department at the University of Illinois at Chicago. "There are a lot of hard problems to solve."

But other experts say the idea recently has become more practical because of the proliferation of computerized devices, from universal remote controls, MP3 players, air conditioning equipment and microwave ovens to security systems, lawn-sprinkler controllers, exercise equipment and toys. Because many of these devices come with cameras, global positioning systems and other sensors to monitor what's around them, these experts say, it's not hard to imagine them gathering enough data about people to
act autonomously on their behalf, assuming the individuals let the gizmos have that authority.

One product that already claims to partly think for its owner is a "personal assistant" app for the iPhone and iPod developed by Siri, a San Jose company Apple bought in April.

Besides being able to recommend a good play, book a taxi and offer helpful reminders, the app -- which responds to verbal queries -- "adapts to your preferences over time," Siri claims. For example, ask it about a good place to eat nearby and it might suggest a certain type of restaurant you have picked before, a company spokesman said. He added that the app also can learn to recognize a person's voice and speaking style, which might make it easier for it to understand what the person is saying on a noisy street. Other
products could be on the way soon, said Diane Cook, a researcher at Washington State University, which has an experimental smart house filled with such devices.

"We have companies large and small and in-between visiting us monthly -- IBM, Bosch, Qualcomm -- all wanting to commercialize it, all trying to decide what that first step is, that first niche," she said.

Stanford University operates a similar research lab. When it hosted a workshop on the technology three weeks ago, it attracted interest from Facebook, Google, Honda, Intel, Microsoft, Nokia, Panasonic, Sony and Hewlett-Packard, according to the lab's website.

Hamid Aghajan, who supervises the lab, foresees gadgets knowing enough about their human housemates to select appropriate lighting and music when the people are eating or reading, coaching them on their speaking skills during meetings and connecting them via social networking sites with people the gadgets determine share their interests.

Peter Harwell, a senior researcher at HP, believes such devices could be built into new homes within a decade or so, though he cautions they must operate "in a way that doesn't annoy the user."

One initial application of the technology is expected to be monitoring the elderly in their homes.

Oregon Health & Science University researchers say they have detected the onset of dementia in older people by using smart pill containers that record whether the person takes their medicine and motion sensors that can tell if their walking and dressing slowed, potential early signs of the disease.

Some experts believe it will be possible for a refrigerator with the right sensors to keep track of how much a person eats and to urge them verbally to adjust their calorie intake. And if the person gets seriously sick, these experts say, other gadgets might be able to detect the illness and alert authorities.

Even the military is interested. The Defense Advanced Research Projects Agency hopes to develop computerized assistants for commanders that "can reason, learn from experience, be told what to do, explain what they are doing, reflect on their experience and respond robustly to surprise."

All this raises concerns for Eric Goldman, who directs Santa Clara University's High Tech Law Institute. One issue is how to protect the privacy of the information the gadgets accumulate on people. "The more data we gather the more the government is going to want to get its paws on it," he said, adding that lawyers in court cases may try to obtain it, too. There also is no guarantee such a device "will do exactly what we want it to," he warned. "There is always the possibility that the smart agent will go rogue."

But others consider the potential benefits worth pursuing. That includes using the technology to rescue people from uncomfortable situations.

If a person gets a call from someone who stresses them out, according to Intel officials, their savvy phone might automatically switch the caller into a voice message. Another intriguing possibility could arise if the phone notices its owner is extremely tense in a meeting, added Lama Nachman, a researcher at the chipmaker. In that case, it might respond with what she termed an "exit phone call," a bogus ring that gives the person a convenient excuse to leave.

Weapons of mass moral corruption (MMC) ? - electromagnetic interference (EMI)

The conspiracy theorists will likely jump all over this one. Wait a minute-come to think of it, this research makes me a little nervous too !!

It's well known that the Russians bombard the US embassy in Moscow with electromangnetic waves or pulses.

"From the public medical literarture, we know that the magnetic component of the electromagnetic field  is psychoactive and can cause mood or behavior changes. These fields can cause brain entrainment, a state when the brain mirrors the pulse rate of the external artificial signal which cause changes in the body and mind.

In a Feb 1985 Omni Magazine story called The Mind Fields, the military was quoted as concluding that "with the right electromagnetic field you might be able to produce the same effects as psychoactive drugs."

Both the Soviet and American military have long been well aware of the health effect of low level radio frequencey waves of 5-12 pulses per second (Hertz) and at very low energy levels (25 nanoteslas)

• 6 Hz- Headaches reported
• 6.66 Hz and lower- nausea, headaches, confusuion and depressive anxiety
• 7.8 Hz, 8Hz, 9Hz- produced alpha rhythms often reched in meditation and a sense of well being
• 10.35 Hz- created agitated anxiety, fear and hostile aggressive behavior
• 11 Hz-induced riotous behavior

Now we see that moral judgments can be altered or swayed  ... by magnetic fields too.

By disrupting brain activity in a particular region, neuroscientists at MIT can sway people’s views of moral situations. To make moral judgments about other people, we often need to infer their intentions — an ability known as “theory of mind.” For example, if one hunter shoots another while on a hunting trip, we need to know what the shooter was thinking: Was he secretly jealous, or did he mistake his fellow hunter for an animal?

MIT neuroscientists have now shown they can influence those judgments by interfering with activity in a specific brain region — a finding that helps reveal how the brain constructs morality.

Previous studies have shown that a brain region known as the right temporo-parietal junction (TPJ) is highly active when we think about other people’s intentions, thoughts and beliefs.  In the new study, the researchers disrupted activity in the right TPJ by inducing a current in the brain using a magnetic field applied to the scalp.  They found that the subjects’ ability to make moral judgments that require an understanding of other people’s intentions — for example, a failed murder attempt — was impaired.  The researchers, led by Rebecca Saxe, MIT assistant professor of brain and cognitive sciences, report their findings in the Proceedings of the National Academy of Sciences the week of March 29.  Funding for the research came from The National Center for Research Resources, the MIND Institute, the Athinoula A. Martinos Center for Biomedical Imaging, the Simons Foundation and the David and Lucille Packard Foundation.

The study offers “striking evidence” that the right TPJ, located at the brain’s surface above and behind the right ear, is critical for making moral judgments, says Liane Young, lead author of the paper.  It’s also startling, since under normal circumstances people are very confident and consistent in these kinds of moral judgments, says Young, a postdoctoral associate in MIT’s Department of Brain and Cognitive Sciences.

“You think of morality as being a really high-level behavior,” she says.  “To be able to apply (a magnetic field) to a specific brain region and change people’s moral judgments is really astonishing.”

Thinking of others

Saxe first identified the right TPJ’s role in theory of mind a decade ago — a discovery that was the subject of her MIT PhD thesis in 2003.  Since then, she has used functional magnetic resonance imaging (fMRI) to show that the right TPJ is active when people are asked to make judgments that require thinking about other people’s intentions.

In the new study, the researchers wanted to go beyond fMRI experiments to observe what would happen if they could actually disrupt activity in the right TPJ.  Their success marks a major step forward for the field of moral neuroscience, says Walter Sinnott-Armstrong, professor of philosophy at Duke University.

“Recent fMRI studies of moral judgment find fascinating correlations, but Young et al usher in a new era by moving beyond correlation to causation,” says Sinnott-Armstrong, who was not involved in this research.

The researchers used a noninvasive technique known as transcranial magnetic stimulation (TMS) to selectively interfere with brain activity in the right TPJ.  A magnetic field applied to a small area of the skull creates weak electric currents that impede nearby brain cells’ ability to fire normally, but the effect is only temporary.

In one experiment, volunteers were exposed to TMS for 25 minutes before taking a test in which they read a series of scenarios and made moral judgments of characters’ actions on a scale of one (absolutely forbidden) to seven (absolutely permissible).  In a second experiment, TMS was applied in 500-milisecond bursts at the moment when the subject was asked to make a moral judgment.  For example, subjects were asked to judge how permissible it is for a man to let his girlfriend walk across a bridge he knows to be unsafe, even if she ends up making it across safely.  In such cases, a judgment based solely on the outcome would hold the perpetrator morally blameless, even though it appears he intended to do harm.  In both experiments, the researchers found that when the right TPJ was disrupted, subjects were more likely to judge failed attempts to harm as morally permissible.  Therefore, the researchers believe that TMS interfered with subjects’ ability to interpret others’ intentions, forcing them to rely more on outcome information to make their judgments.

“It doesn’t completely reverse people’s moral judgments, it just biases them,” says Saxe.

While understanding other people’s intentions is critical to judging them, it is just one piece of the puzzle.  We also take into account the person’s desires, previous record and any external constraints, guided by our own concepts of loyalty, fairness and integrity, says Saxe.

“Our moral judgments are not the result of a single process, even though they feel like one uniform thing,” she says.  “It’s actually a hodgepodge of competing and conflicting judgments, all of which get jumbled into what we call moral judgment.”

Saxe’s lab is now studying the role of theory of mind in judging situations where the attempted harm was not a physical threat.  The researchers are also doing a study on the role of the right TPJ in judgments of people who are morally lucky or unlucky.  For example, a drunk driver who hits and kills a pedestrian is unlucky, compared to an equally drunk driver who makes it home safely, but the unlucky homicidal driver tends to be judged more morally blameworthy.

Magnets over the right ear, you say ? eh? That's called cell phone use. So could cell phones become the next huge health stigma or the cigaretes of the 1980 or 1970's?

When will the recession end ? Part 45 Big Brother in China

First there were reports of the Chinese government hacking gmail google accounts.

Now, the NYT reports:

"As the Chinese government expands what it calls a campaign against pornography, cellular companies in Beijing and Shanghai have been told to suspend text services to cellphone users who are found to have sent messages with "illegal or unhealthy content," state-run news media reported. China Mobile, one of the nation's largest cellular providers, reported that text messages would automatically be scanned for "key words" provided by the police, according to China Daily, a state-controlled English-language newspaper. Messages will be deemed "unhealthy" if they violate undisclosed criteria established by the central government, the newspaper said."

Technology, Control, Happiness and Depression: Is technology controlling you and your life or vise a versa?

(Graphic from New Scientist)  Just sit back and think for a moment: how long has it been since you read your last email? Scanned your last last Twitter?  Dispatched you previous text message? Updated Facebook or Linked In?

With the annual homage to the  Mecca of consumer materialism -the consumer electronics show  (CES) in  Vegas this month ,it may be appropriate to ask the bigger social question

Is technology controlling you and your life or vise a versa?  

Yair Amichai-Hamburger offers  a provocative opinion piece on this month’s issue of New Scientist (Dec 27, 2009 volume 2739) titled “Shiny unhappy People” in the print version or “Free yourself from oppression by technology.” In  the online version

From his Tetrad model, Marshall McLuhan reminds us that technology has four simultaneous impacts on society...and in this case, here's my take on the social impacts and secondary consequences of communication technologies

 

1)Something gets enhanced?  (materialism, consumption, depression, a stecato culture of information, continuous interruption, a middle class that's under the influence of mass cultural and perpetual distraction, fragmentation of reactive efforts, sense of being overwhelmed and not knowing were to turn, public passivity, digital version of divide to conquer etc )

2) something gets obsolesced or lost?  (social relationships, happiness, tenacity & longevity of thought, thoroughness,  propensity for societal action, coordinated social response)

3) something gets brought back or retrieved? (digital-slavery, time enslavement ) and

4) something gets flipped or reversed?  (from ease of communication to communication stress &Info overload or what I call pauperization of communication & information, debasted or watered-down wisdom)

 

Amichai-Hamburger touches on  all 4 of these social impacts- enhancement, retrieval, obsolescence, and reversal.

 

Here’s a recap and summary of his key points

• "Are we being served by these technological wonders or have we become enslaved by them?"
• We living in an"age of melancholy" coined by psychologist Daniel Goleman to describe our era. "People today experience more depression than previous generations, despite the technological wonders that help us every day. It might be because of them."
• "Our lifestyles are increasingly driven by technology. Phones, computers and the internet pervade our days. There is a constant, nagging need to check for texts and email, to update Facebook, MySpace and LinkedIn profiles, to acquire the latest notebook or 3G cellphone. "
• "For many of us it is becoming increasingly difficult to control the impulse to check our inbox yet again or see whether the headlines have changed since we last looked. [...] In many homes, the computer has become the centre of attention; it is the medium through which we work and play."
• "How did this arise, and what is it doing to us? In this era of mass consumption, we are surrounded by advertising that urges us to find fulfillment through the acquisition of material goods. As a result, adults and children increasingly believe that in order to belong and feel good about themselves, they must own the latest model or gadget."
• "Yet research has shown that people who place a high value on material goals are unhappier than those who are less materialistic. Materialism is also associated with lower self-esteem, greater narcissism, greater tendency to compare oneself unfavorably with other people, less empathy and more conflict in relationships."
• "People who place a high value on material goals are unhappier than those who are less materialistic "--N.B. this is supported by other studies that show consumers value "experiential events" over "material goods"--Walter Derzko
• "Our culture also constantly reminds us that time is money. This implies a need for total efficiency, which is why we are allowing laptop computers and mobile phones to blur the separation between work and home. As one unhappy human-resource manager in a high-tech company put it: "They gave me a mobile phone so they can own me 24 hours a day, and a portable computer, so my office is now with me all the time - I cannot break out of this pressure." Sound familiar?"
• "Psychologists generally believe that the lack of a clear separation between work and home significantly damages our relationships with loved ones. It also predisposes us to focus on the here and now at the expense of long-term goals."
• "By imposing these twin pressures, modern society is in danger of swapping standard of living for quality of life. We need ways to help recover those increasingly large parts of our lives that we have ceded to technology, to regain mastery over technology and learn to use it in a healthy and positive way."
• Amichai-Hamburger offers a 4 point  prescription to reagin self-control based on  self-determination theory, developed by psychologists Edward Deci and Richard Ryan of the University of Rochester in New York state. It identifies three vital elements of healthy personal development and functioning that  can be used to recalibrate our relationship with technology. Amichai-Hamburger  thenadds a 4th point below.

1) "The first is autonomy - the feeling that our activities are self-chosen and self-endorsed. When we feel in control, we are able to organize our priorities and place effective boundaries around them. But when we feel we have insufficient control, it leaves us vulnerable to our impulses and causes us to abdicate decisions to other people. It is easy to see how technology undermines autonomy, but also how to regain it. This may be as simple as switching off mobile phones during meals and family time, setting aside specific times to answer emails, and being available only when we choose to be."

2) "We also need a sense of competence, a belief that our actions are effective. In this respect our relationship with technology is complex, because many of us feel competent when we deal with an email, when we have the newest BlackBerry, or because 50 people enjoyed the holiday snaps we posted on Facebook. "

3) "Relatedness:our need to feel close to other people. Technology is a threat to this. Devices like the iPod can be used to create a bubble that disconnects us from normal human interactions, and while some virtual relationships may be truly meaningful, in many cases they come at the expense of real-world connections. Psychologists have found that the pivotal difference between happy and unhappy people is the presence or absence of rich and satisfying social relationships. Spending meaningful time with friends, family and partners is necessary for happiness."

Many North American's have lost this, which is why seemingly poorer nations tend to be happier --Walter Derzko.

4) "Critical thinking. In today's world, where we are potentially available 24/7 to absorb messages from well-honed advertisements, it is vital that we know how to analyze and evaluate their validity - and to neutralize them where necessary."

Autonomy, competence, relatedness and critical thinking are the best ways to establish a balanced approach to technology, and so enhance our well-being.

Intersting question to ponder...will Eastern & Asian cultures (India, China etc) turn to North American ideals of materialism & consumption to find fullfillment in life as they develop economically or to something else?--Walter Derzko

When will the recession end? Part 27 The Sun could create a double dip depression

New Solar Cycle 24 Prediction: Fewer Sunspots, But Severe Mass Coronal Ejection (MCE) Activity possible.

 

In the past, human populations have survived 7 climate change-related mass extinction events...James Lovelock reminds us...but are we more vulnerable now and less resilient as a society?

 

Now privately, some scientists are quietly predicting two imminant wild card possibilities-a mini ice age, that could punctuate global warming,  if sun spots do not pick up in the next solar spot cycle and the distinct possibility of severe solar storms. At the extreme, both events could cause billions of deaths in a worst case scenario that we looked at last month.

 

Publically, an  international panel of experts has released a new prediction for the next solar cycle, stating that Solar Cycle 24 will peak in May 2013with a below-average number of sunspots. Led by the National Oceanic and Atmospheric Administration (NOAA) and sponsored by NASA, the panel includes a dozen members from nine different government and academic institutions. Their forecast sets the stage for at least another year of mostly quiet conditions before solar activity resumes in earnest [..they hope].

"If our prediction is correct, Solar Cycle24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78," says panel chairman Doug Biesecker of the NOAA Space Prediction Center, Boulder, Colo.

 It is tempting to describe such a cycle as "weak" or "mild," but that could give the wrong impression. "Even a below-average cycle is capable of producing severe space weather,"says Biesecker. "The great geomagnetic storm of 1859, for instance, occurred during a solar cycle of about the same size we’re predicting for 2013."

The 1859 storm -- named the "Carrington Event" after astronomer Richard Carrington who witnessed the instigating solar flare -- electrified transmission cables, set fires in telegraph offices, and produced Northern Lights so bright that people could read newspapers by their red and green glow. A recent report by the National Academy of Sciences found that if a similar storm occurred today, it could cause $1 to 2 trillion in damages to society’s high-tech infrastructure and require four to ten years for complete recovery. For comparison, Hurricane Katrina caused $80 to 125 billion in damage.

 

 

The latest forecast revises a prediction issued in 2007, when a sharply divided panel believed solar minimum would come in March 2008 and would be followed by either a strong solar maximum in 2011 or a weak solar maximum in 2012. Competing models of the solar cycle produced different forecasts, and researchers were eager for the sun to reveal which was correct.

"It turns out that none of the models were really correct,"says Dean Pesnell of the Goddard Space Flight Center, Greenbelt, Md. NASA’s lead representative on the panel. "The sun is behaving in an unexpected and very interesting way."

Astronomers first noted the solar cycle in the mid-1800s. Graphs of sunspot numbers resemble a roller coaster, going up and down with an approximately 11-year period. Predicting the peaks and valleys has proven troublesome because cycles vary in length from 9 to 14 years. Some peaks are high, others low. The valleys are usually brief, lasting only a couple of years, but sometimes they stretch much longer. In the 17th century, the sun plunged into a 70-year period of spotless quiet known as the Maunder Minimum (mini ice age) that still baffles scientists.

At a recent climate change symposium at Monash University in Australia, David Archibald, an expert in solar cycles stated:

“You haven’t seen any sign of the end of Solar Cycle 23 yet and the cooling over Solar
Cycle 24 as a consequence may be as much as 2.8 degrees centigrade. We are due for a de Vries cycle cooling event every two hundred and ten years, and actually even a Bond event because the last one of those was in the Dark Ages. And severe cooling over the next twenty years is now a certainty.” 

Right now, the solar cycle is in a valley--the deepest of the past century. In 2008 and 2009, the sun set Space Age records for low sunspotcounts, weak solar wind, and low solar irradiance. The sun has gone more than two years without a significant solar flare.

"In our professional careers, we’ve never seen anything quite like it," says Pesnell. "Solar minimum has lasted far beyond what we predicted in 2007."

 

 

In recent months, however, the sun has begun to show signs of life. Small sunspots and "proto-sunspots" are popping up with increasing frequency. Enormous currents of plasma on the sun’s surface ("zonal flows") are gaining strength and slowly drifting toward the sun’s equator. Radio astronomers have detected a tiny but significant uptick in solar radio emissions. All these things are precursors of an awakening Solar Cycle 24 and form the basis for the panel’s new, almost unanimous forecast.

 

 

According to the forecast, the sun should remain generally calm for at least another year. From a research point of view, that’s good news because solar minimum has proven to be more interesting than anyone imagined. Low solar activity has a profound effect on Earth’s atmosphere, allowing it to cool and contract. Space junk accumulates in Earth orbit because there is less aerodynamic drag. The becalmed solar wind whips up fewer magnetic storms around Earth’s poles. Cosmic rays that are normally pushed back by solar wind instead intrude on the near-Earth environment. There are other side-effects, too, that can be studied only so long as the sun remains quiet.

 

Meanwhile, the sun pays little heed to human committees. There could be more surprises, panelists acknowledge, and more revisions to the forecast.

"Go ahead and mark your calendar for May 2013," says Pesnell. "But use a pencil."

Why sustainable power is unsustainable?- advanced "renewable" technologies are too often based upon non-renewable resources

Recessions and depressions are great periods in history because paradoxes and contradictions seem to stand out even more. The big one facing society in the next two decades is the obvious economic one-everything in our conventional economic paradigm is based on annual, year-over-year growth, yet we appear to be entering a period of "peak resources" ranging from peak water, to peak oil, peak gas and most importantly for business, peak minerals-facts that the green eco-movement often ignores, or is hiding in the closet-the dirty green secret.

A story earlier this month in New Scientist, covered a Financial Times conference on energy and sustainability in London England and it concludes:

"Renewable energy needs to become a lot more renewable...[..]... Although scientists are agreed that we must cut carbon emissions from transport and electricity generation to prevent the globe's climate becoming hotter, and more unpredictable, the most advanced "renewable" technologies are too often based upon non-renewable resources, attendees heard. Supratik Guha of IBM told the conference that sales of silicon solar cells are booming, with 2008 being the first year that the silicon wafers for solar cells outstripped those used for microelectronic devices. But although silicon is the most abundant element in the Earth's crust after oxygen, it makes relatively inefficient cells that struggle to compete with electricity generated from fossil fuels. And the most advanced solar-cell technologies rely on much rarer materials than silicon [-that being indium.]"

[..]...Peak Indium? 10 year of global supply left?

"The efficiency of solar cells is measured as a percentage of light energy they convert to electricity. Silicon solar cells finally reached 25% in late December. But multi-junction solar cells can achieve efficiencies greater than 40%.

 

Although touted as the future of solar power, those and most other multiple-junction cells owe their performance to the rare metal indium, which is far from abundant. There are fewer than 10 indium-containing minerals, and none present in significant deposits – in total the metal accounts for a paltry 0.25 parts per million of the Earth's crust.

 

Most of the rare and expensive element is used to manufacture LCD screens, an industry that has driven indium prices to $1000 per kilogram in recent years. Estimates that did not factor in an explosion in indium-containing solar panels reckon we have only a 10 year supply of it left.

If power from the Sun is to become a major source of electricity, solar panels would have to cover huge areas, making an alternative to indium essential."

Could we see resource wars, {which the US military has extensive plans for}, material rationing or outright prohibition like we saw with alcohol in the 1930's? Will we have to select between indium for our cell phones, flat screen TV's or solar cells? Will nanotech breakthroughs come to the rescue? -will an exotic combination of fullerenes, graphenes and carbon nanotubes be the substitution answer? The nanotech race for an alternative is on.--Walter Derzko

 

They also cover peak Platinum

"The dream of the hydrogen economy faces similar challenges, said Paul Adcock of UK firm Intelligent Energy. A cheap way to generate hydrogen has so far proved elusive. New approaches, such as using bacterial enzymes to "split" water, have a long way to go before they are commercially viable. So far, fuel cells are still the most effective way to turn the gas into electricity. But these mostly rely on expensive platinum to catalyse the reaction.

The trouble is, platinum makes indium appear super-abundant. It is present in the Earth's crust at just 0.003 parts per billion and is priced in $ per gram, not per kilogram. Estimates say that, if the 500 million vehicles in use today were fitted with fuel cells, all the world's platinum would be exhausted within 15 years. Unfortunately platinum-free fuel cells are still a long way from the test track. A nickel-catalysed fuel cell developed at  Wuhan University, China, has a maximum output only around 10% of that a platinum catalyst can offer.

A new approach announced yesterday demonstrates that carbon nanotubes could be more effective, as well as cheaper, than platinum. But again it will be many years before platinum-free fuel cells become  a commercial prospect."

Also , could Lithium shortages in 10-15 years  impede future electric car deployment?

 

Let’s look at the  metal gallium, which along with indium is used to make the next generation of semiconductor materials-indium gallium arsenide for a new generation of solar cells that promise to be up to twice as efficient as conventional designs. Reserves of both metals are disputed, but in a 2007 report Renï  Kleijn, from LeidenUniversity in the Netherlands, concludes that current reserves "would not allow a substantial contribution of these cells" to the future supply of solar electricity. He estimates gallium and indium will probably contribute to less than 1 per cent of all future solar cells - a limitation imposed purely by a lack of raw material."

Other projections I've seen-antimony could run out in 10 years; Silver in 10 years, hafnium in 10-15 years and tribium by 2012 or 4-5 years. Looking for the next geopolitical flash point? The US imports 90% of its rare metals and materials from China.

(Proceedings of the National Academy of Sciences, vol 103, p 1209), "Virgin stocks of several metals appear inadequate to sustain the modern 'developed world' quality of life for all of Earth's people under contemporary technology."

 

I've always wondered what minerals are hidden in the mountains of Afghanistan.... "It is widely acknowledged that one of the key motives for civil war in the Democratic Republic of the Congo between 1998 and 2002 was the riches to be had from the country's mineral resources, including tantalum mines - the biggest in Africa. The war coincided with a surge in the price of the metal caused by the increasing popularity of mobile phones." (New Scientist, 7 April 2001, p 46).

 

 

Ever wonder why China is hoarding every gram of our high tech electronic garbage?  It's buying up high-tech scrap to extract metals that are key to its developing industries.

 

One good thing about this recession / depression shakeout-there will be far fewer firms fighting and scrambling over those increasingly precious resources-buying us a few extra years of transition time.

 

The lessons here?...Digging minerals out of the ground will no longer automatically confer economic advantage {Canada, Africa, Brazil and China Listen Up}, instead structuring "smart materials" in novel ways will.--Walter Derzko
