New solar fuel machine 'mimics plant life'

 

  http://www.bbc.co.uk/news/science-environment-12051167


  (Dec. 23, 2010)   -  The machine uses the Sun's rays and a metal oxide called ceria

to break down carbon dioxide or water into fuels which can be stored and transported.

Conventional photovoltaic panels must use the electricity they generate in situ, and cannot deliver power at night.

Details are published in the journal Science.

The prototype, which was devised by researchers in the US and Switzerland,

uses a quartz window and cavity to concentrate sunlight into a cylinder lined with cerium oxide, also known as ceria.

Ceria has a natural propensity to exhale oxygen as it heats up and inhale it as it cools down.

If as in the prototype, carbon dioxide and/or water are pumped into the vessel,

the ceria will rapidly strip the oxygen from them as it cools, creating hydrogen and/or carbon monoxide.

Hydrogen produced could be used to fuel hydrogen fuel cells in cars, for example,

while a combination of hydrogen and carbon monoxide can be used to create "syngas" for fuel.

It is this harnessing of ceria's properties in the solar reactor which represents the major breakthrough,

say the inventors of the device. They also say the metal is readily available, being the most abundant of the "rare-earth" metals

Study: Conservatives have larger ‘fear center’ in brain

 

  http://www.rawstory.com/rs/2010/12/conservatives-fear-center-brain/

 

(Dec. 28, 2010)

 

  ‘Political opinions are considered choices,

and in Western democracies the right to choose one's opinions

-- freedom of conscience --

is considered sacrosanct.

But recent studies suggest that our brains and genes

may be a major determining factor in the views we hold.



A study at University College London in the UK has found that

conservatives' brains have larger amygdalas than the brains of liberals.

Amygdalas are responsible for fear and other "primitive" emotions.

At the same time, conservatives' brains were also found to have a smaller anterior cingulate --

the part of the brain responsible for courage and optimism.

If the study is confirmed,

it could give us the first medical explanation for why

conservatives tend to be more receptive to threats of terrorism, for example, than liberals.

And it may help to explain why conservatives like to plan based on the worst-case scenario,

while liberals tend towards rosier outlooks.’

 

 

How the size of our brain means we all view the world in a different way

  http://mcaf.ee/efa2d

(December 8, 2010) - (Daily Mail)

“The way we view the world depends on the size of one small part of our brain, according to a new study,

The primary visual cortex - the area at the back responsible for processing what we view around us -

is known to vary in size by up to three times from one individual to the next.

This affects the way we see the world, meaning we all see the world differently researchers say.”

Nanotechnology: Detecting Lethal Diseases With Rust and Sand



Graphene etching to usher in computing revolution - (March 3, 2011 by Jessica Griggs)  - http://mcaf.ee/d965c -  Move over sticky tape: a splattering of zinc atoms and a dash of acid is the best way to peel off single layers of graphene, the atom-thin form of carbon that electrons can zip through with incredible efficiency and speed.

This technique is so precise that it might be possible to create electrical circuits using only graphene components, which could allow this exotic material to realise its potential as the basis for ultra-efficient, super-fast computer chips.

[Excerpt taken from a “White Paper” article by Zack Stern

on p.p. 54-55 of the Feb. 2011 issue

of Maximum PC magazine ( www.maximumpc.com )]:


 Graphene

A recently isolated material

could advance displays, batteries,

solar cells, and computers beyond silicon


     In its sheet form, it’s the first two-dimensional, crystalline substance

that’s ever been isolated, it can be rolled into tubes

-- carbon nanotubes --

that behave as a single-dimension material,

and can even be made into a zero-dimensional ball.

These multidimensional properties allow for new research

and experiments down to a quantum physics level.


      ….  …the virtually clear substance;

about 98 percent of light passed through the layer.  ….


     ….  Two hundred times stronger than steel,

it’s possibly the lightest, strongest material ever discovered,

suitable for airplane parts an other

high-pressure, low-weights applications.

It conducts electricity with an extremely low resistance

-- faster than silicon --

making it suitable for many electronic applications.


     These traits, combined with graphene’s transparency,

could also make the material a key component

in building more functional lightweight OLED

[Organic Light-Emitting Diodes],

LCD, and touch-screen panels.

And with its large surface-to-volume ratio,

graphene in powder form could even improve batteries.

     graphene could be built into tiny transistors

that can move single electrons around

with electromagnetic forces.  ….


Theoretically, these transistors would be smaller,

consume less power, and yield much higher speeds than current silicon.  ….


     …you can expect to see the first commercial uses of graphene

in the next two to three years.

More ambitious usage will, of course, take decades to develop.

This said, some companies, such as Samsung,

are already testing 30-inch graphene-based display prototypes.

 


Graphene Put To Use…

In The Near Future:


A Day Made of Glass... Made possible by Corning.”

Bacteria thrive amid carbon nanotubes, study finds

(CBC News  - March 26, 2007)

 

A super-strong nanomaterial with potential industrial and medical applications

inhibits growth in mammalian cells while sustaining the growth of bacteria, according to two studies.


Researchers at Rensselaer Polytechnic Institute in Troy, N.Y.,

also found the size, type and concentration of carbon nanotubes

changed their interaction with living cells.


The authors suggest the seemingly contradictory results

suggest the environmental and health impacts of the nanomaterial

are more complex than first thought and demand further study.


The first study, published in the journal Toxicology Letters,

found that the material inhibited the growth of heart muscles in rats.

 The effect was seen with large clusters of nanotubes

and even more so when the nanotubes were finely dispersed.


The second study found the material had an opposite effect on bacteria,

actually sustaining growth of samples of Escherichia coli (E. coli).


Both studies were presented Sunday

at the 233rd American Chemical Society (ACS) National Meeting in Chicago.

Invention: Self-replicating materials

(NewScientist - Nov. 3, 2008)


…a new patent application,

is based on the fact that sequences of DNA

can be designed to recognise and bond with each other.

By carefully designing these sequences, it is possible to build structures from them….


…these techniques can be used to build with micrometre-sized particles of plastic, glass or metal,

by coating them with DNA. Using the right sequences, they can induce such particles to assemble themselves into complex objects.


These assemblies can in turn self-replicate by corralling other DNA-tagged particles into more versions of the same thing.  ….


The ability to create new materials in this way

could provide new routes to building regular structures like those used in microelectronics.

Or it could produce entirely new materials, such as photonic crystals

that control the movement of light through them in a way akin to how electricity flows through a semiconductor.

Human hair linked to dinosaur claws

                                                                                   

(By Jennifer Viegas - Nov. 11, 2008 - Discovery Channel)

 

Origins of hair go back 310 million years to common ancestor

      Lizards are not hairy, but their claws contain proteins nearly identical to those found in the human hair shafts, fingernails and toenails.

'No Sun link' to climate change


(BBC News - July 10, 2007)

A new scientific study concludes that

changes in the Sun's output

cannot be causing modern-day climate change.


It shows that for the last 20 years,

the Sun's output has declined,

yet temperatures on Earth have risen.


It also shows that modern temperatures

are not determined by

the Sun's effect on cosmic rays,

as has been claimed.

Milstar:  “Look Ma, no hands!”

 

There is a real-life,

computer-automated/programmed

“robot war” system

already in place

that utilizes satellite telemetry/sensing.

  It’s code-named “Milstar.”


 Essentially what “Milstar” has done

is take the “auto-pilot” control of nuclear launch capability

out of the hands of “fallible”, “slow-to-act/respond” real live humans!

  The Milstar system employs those DSP (Deep Space Platform) satellites,

and both hard-to-track mobile and below-ground

“hardened” nuclear strike/response facilities,

and ties them all together

under this now-fully-automated/functioning system.


Of course, nothing could ever go “wrong”

with a no-human-intervention system

like that, now could it!?!

Blank Check: The Pentagon’s Black Budget

written by Pulitzer Prize-winning reporter

(of the “Philadelphia Enquirer”) Tim Weiner.


  The 1990 book (ISBN 0-446-51452-7)

was published by Warner Book, Inc.,

666 Fifth Ave., New York, NY 10103.

 

[From the book’s back cover]:


“Tim Weiner...uncovers the Pentagon’s big secret: $100 million a day to spend any way it sees fit, whether it serves or disserves the American people.  He deserves another Pulitzer Prize for this one.” --- Studs Terkel

 

“Tim Weiner shines his searchlight on dark corners that the Pentagon would like to keep hidden from the American public.” --- David Wise, author of The Spy Who Got Away, and, The Invisible Government

 

“The Pentagon’s $36 billion black budget is a license to steal.  In BLANK CHECK, Pulitzer Prize-winning Tim Weiner tells the entire, shocking story.” --- U.S. Rep. Patricia Schroeder, (D., Colo.), member, House Armed Services Committee

 

[From the book’s inside flyleaf]:


BLANK CHECK is the story of the Pentagon’s secret budget—the black budget.  A remarkable work of investigative reporting, this book presents the first detailed look into the multibillion-dollar cache used to fund every defense program, every espionage mission, every weapon, and every war that the President, the Secretary of Defense and the Director of the CIA want erased from the public ledger and shielded from public debate.

Over the past three years, the black budget has consumed more than $100 billion -- $100 million a day.  In blatant defiance of the United States Constitution, this system of secret spending has stripped Congress of its power over the federal budget and robbed taxpayers of their right to know how their money is spent.

Scientists unveil the world's smallest computer that is just 1 SQUARE MILLIMETRE  -  (February 25,  2011 - The Daily Mail)  -  Scientists have created the world's smallest computer system to help treat glaucoma patients.

At just one square millimetre in size, the tiny device is a pressure monitor that is implanted in a person's eye.

It may be small but it packs a hefty punch, containing an ultra low-power microprocessor, a pressure sensor, memory, a thin film battery, a solar cell and a wireless radio with an antenna that can transmit data to an external reader device.

Developed by researchers at the University of Michigan, the unnamed unit - which is expected to be commercially available in several years - is already being touted as the future of the computing industry.

Its creators - Professors Dennis Sylvester, David Blaauw and David Wentzloff - claim that as the device's radio needs no tuning to find the right frequency it could link to a wireless network of computers.

A network of such units could one day track pollution, monitor structural integrity, perform surveillance, or make virtually any object smart and trackable, according to the scientists.  -  http://mcaf.ee/cedbf

Breakthrough in Nanocomposite for High-Capacity Hydrogen Storage  -  ScienceDaily (Mar. 14, 2011) — Since the 1970s, hydrogen has been touted as a promising alternative to fossil fuels due to its clean combustion -- unlike hydrocarbon-based fuels, which spew greenhouse gases and harmful pollutants, hydrogen's only combustion by-product is water. Compared to gasoline, hydrogen is lightweight, can provide a higher energy density and is readily available. But there's a reason we're not already living in a hydrogen economy: to replace gasoline as a fuel, hydrogen must be safely and densely stored, yet easily accessed.

Smaller Particles Could Make Solar Panels More Efficient  -  ScienceDaily (Mar. 25, 2011) — Studies done by Mark Lusk and colleagues at the Colorado School of Mines could significantly improve the efficiency of solar cells. Their latest work describes how the size of light-absorbing particles--quantum dots--affects the particles' ability to transfer energy to electrons to generate electricity.

The results are published in the April issue of the journal ACS Nano.

The advance provides evidence to support a controversial idea, called multiple-exciton generation (MEG), which theorizes that it is possible for an electron that has absorbed light energy, called an exciton, to transfer that energy to more than one electron, resulting in more electricity from the same amount of absorbed light.

Quantum dots are human-made atoms that confine electrons to a small space. They have atomic-like behavior that results in unusual electronic properties on a nanoscale. These unique properties may be particularly valuable in tailoring the way light interacts with matter.    -  http://www.sciencedaily.com/releases/2011/03/110325164217.htm




'Nano-Bricks' May Help Build Better Packaging to Keep Foods Fresher Longer



Debut of the First Practical 'Artificial Leaf'  -  ScienceDaily (Mar. 28, 2011) — Scientists have claimed one of the milestones in the drive for sustainable energy -- development of the first practical artificial leaf. Speaking in Anaheim, California at the 241st National Meeting of the American Chemical Society, they described an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.

"A practical artificial leaf has been one of the Holy Grails of science for decades," said [MIT professor] Daniel Nocera, Ph.D., who led the research team. "We believe we have done it. The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. Our goal is to make each home its own power station," he said. "One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this technology."

The device bears no resemblance to Mother Nature's counterparts on oaks, maples and other green plants, which scientists have used as the model for their efforts to develop this new genre of solar cells. About the shape of a poker card but thinner, the device is fashioned from silicon, electronics and catalysts, substances that accelerate chemical reactions that otherwise would not occur, or would run slowly. Placed in a single gallon of water in a bright sunlight, the device could produce enough electricity to supply a house in a developing country with electricity for a day, Nocera said. It does so by splitting water into its two components, hydrogen and oxygen.

The hydrogen and oxygen gases would be stored in a fuel cell, which uses those two materials to produce electricity, located either on top of the house or beside it.  -  http://www.sciencedaily.com/releases/2011/03/110327191042.htm

'Spincasting' Holds Promise for Creation of Nanoparticle Thin Films



Heavy Metals Open Path to High Temperature Nanomagnets - ScienceDaily (Mar. 30, 2011) — How would you like to store all the films ever made on a device the size of an I-phone? Magnets made of just a few metallic atoms could make it possible to build radically smaller storage devices and have also recently been proposed as components for spintronics devices. There's just one obstacle. Nano-sized magnets have only been seen to work at temperatures a little above absolute zero.

Now a chemistry student at the University of Copenhagen has demonstrated that molecular magnets using the metals ruthenium and osmium retain their magnetic properties at higher temperatures. Most likely due to the larger spin-orbit coupling and more diffuse electron cloud present in these heavier elements. Some of his findings have recently been published in Chemistry -- A European Journal.  -  http://www.sciencedaily.com/releases/2011/03/110328101324.htm

 

 

Fast-Recharge, Lithium-Ion Battery Could Be Perfect for Electric Cars




Novel Nanowires Boost Fuel Cell Efficiency - ScienceDaily (Mar. 31, 2011) — Fuel cells have been touted as a cleaner solution to tomorrow's energy needs, with potential applications in everything from cars to computers.

But one reason fuel cells aren't already more widespread is their lack of endurance. Over time, the catalysts used even in today's state-of-the-art fuels cells break down, inhibiting the chemical reaction that converts fuel into electricity. In addition, current technology relies on small particles coated with the catalyst; however, the particles' limited surface area means only a fraction of the catalyst is available at any given time.

Now a team of engineers at the Yale School of Engineering & Applied Science has created a new fuel cell catalyst system using nanowires made of a novel material that boosts long-term performance by 2.4 times compared to today's technology. Their findings appear on the cover of the April issue of ACS Nano.  -  http://mcaf.ee/c7fe3

Scientist finds a whole new 'domain' of life - It is life but not as we know it – a scientist claims to have discovered not just a new species but a whole new branch of the tree of life. - (April 5, 2011 - By Richard Alleyne, Science Correspondent - The Telegraph/UK)  -  Living things are currently split into three branches or domains – eukaryotes, or complex celled organisms such as animals, plants and humans – and two simple celled microorganism divisions – bacteria and archaea.

But now a researcher working with the laboratory of the maverick scientist Dr Craig Venter claims he might have discovered a fourth.

Professor Jonathan Eisen, an evolutionary biologist at the University of California, has used complicated gene sequencing techniques to look at DNA collected by Dr Venter on a round the world yachting trip.

He found that some of the genes did not fit into the three domains and that he could possibly have stumbled on a whole new domain.

Trying to classify the new DNA has proved impossible and so Prof Eisen has published his findings in the journal Public Library of Science in the hope others can help.   -  http://mcaf.ee/2974e

Rainbow-Trapping Scientist Now Strives to Slow Light Waves Even Further - ScienceDaily (Apr. 12, 2011) — An electrical engineer at the University at Buffalo, who previously demonstrated experimentally the "rainbow trapping effect" -- a phenomenon that could boost optical data storage and communications -- is now working to capture all the colors of the rainbow.

In a paper published March 29 in the Proceedings of the National Academy of Sciences, Qiaoqiang Gan (pronounced "Chow-Chung" and "Gone"), PhD, an assistant professor of electrical engineering at the University at Buffalo's School of Engineering and Applied Sciences, and his colleagues at Lehigh University, where he was a graduate student, described how they slowed broadband light waves using a type of material called nanoplasmonic structures.

Gan explains that the ultimate goal is to achieve a breakthrough in optical communications called multiplexed, multiwavelength communications, where optical data can potentially be tamed at different wavelengths, thus greatly increasing processing and transmission capacity.

He notes that it is widely recognized that if light could ever be stopped entirely, new possibilities would open up for data storage.  -  http://mcaf.ee/0eb17

Nanoparticles With Honeycomb Cavities Containing Drugs Blast Cancer Cells - ScienceDaily (Apr. 18, 2011) — Melding nanotechnology and medical research, Sandia National Laboratories, the University of New Mexico, and the UNM Cancer Research and Treatment Center have produced an effective strategy that uses nanoparticles to blast cancerous cells with a mélange of killer drugs.

In the cover article of the May issue of Nature Materials, available online April 17 , the researchers describe silica nanoparticles about 150 nanometers in diameter as honeycombed with cavities that can store large amounts and varieties of drugs.

"The enormous capacity of the nanoporous core, with its high surface area, combined with the improved targeting of an encapsulating lipid bilayer [called a liposome], permit a single 'protocell' loaded with a drug cocktail to kill a drug-resistant cancer cell," says Sandia researcher and UNM professor Jeff Brinker, the principal investigator.

'Impossible' Feat: Certain Materials Can Exhibit Ferromagnetism and Superconductivity at Same Time - ScienceDaily (Apr. 18, 2011) — It actually seems impossible: Scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden were able to verify with an intermetallic compound of bismuth and nickel that certain materials actually exhibit the two contrary properties of superconductivity and ferromagnetism at the same time. A phenomenon that had only been demonstrated around the globe on a small number of materials and which might provide highly interesting technological opportunities in future.

Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden published their research results in the journal Physical Review B.

Headed by Dr. Thomas Herrmannsdörfer, the team from the HZDR's High Magnetic Field Laboratory (HLD) examined a material consisting of the elements bismuth and nickel (Bi3Ni) with a diameter of only a few nanometers -- which is unique since it has not been achieved elsewhere so far. This was made possible through a new chemical synthesis procedure at low temperatures which had been developed at the TU Dresden under the leadership of Prof. Michael Ruck. The nano scale size and the special form of the intermetallic compound -- namely, tiny fibers -- caused the physical properties of the material, which is non-magnetic under normal conditions, to change so dramatically. This is a particularly impressive example of the excellent opportunities modern nanotechnology can provide today, emphasizes Dr. Thomas Herrmannsdörfer. "It's really surprising to which extend the properties of a substance can vary if one manages to reduce their size to the nanometer scale."  -  http://www.sciencedaily.com/releases/2011/04/110418114007.htm



R/C Car Runs On Aluminum Pull-Tabs - (April 20, 2011 - by Mark Brown - Wired/UK) - This clean and green micro-car runs on something you’d normally just toss away: the aluminum ringpulls that snap off your beer cans.

The all-electric radio controlled vehicle, named “dAlH2Orean”, can zip along at 30km/hr (18 mpg) by turning waste aluminum scraps like ringpulls into hydrogen, and then into power. By mixing water and residual aluminum with sodium hydroxide, hydrogen is generated.

That chemical is then passed through a series of filters to eliminate waste and improve performance. A vinegar filter with water helps remove traces of hydroxides, while another filter containing a silica gel ball gets rid of the moisture. A membrane then separates the electrons from the protons until they meet again in an environment of oxygen.

Once produced, the clean hydrogen feeds the fuel cell that produces the energy for the car. Because it’s a closed cycle, the little machine doesn’t belch out any carbon dioxide emissions.  -  http://www.wired.com/autopia/2011/04/rc-car-runs-on-aluminum-pull-tabs/

Material That If Scratched, You Can Quickly and Easily Fix Yourself, With Light Not Heat - ScienceDaily (Apr. 20, 2011) — Imagine you're driving your own new car--or a rental car--and you need to park in a commercial garage.

Revolutionary New Paper Computer Shows Flexible Future for Smartphones and Tablets - ScienceDaily (May 4, 2011) — The world's first interactive paper computer is set to revolutionize the world of interactive computing.

"This is the future. Everything is going to look and feel like this within five years," says creator Roel Vertegaal, the director of Queen's University Human Media Lab. "This computer looks, feels and operates like a small sheet of interactive paper. You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen."

The smartphone prototype, called PaperPhone is best described as a flexible iPhone -- it does everything a smartphone does, like store books, play music or make phone calls. But its display consists of a 9.5 cm diagonal thin film flexible E Ink display. The flexible form of the display makes it much more portable that any current mobile computer: it will shape with your pocket.

Dr. Vertegaal will unveil his paper computer on May 10 at 2 pm at the Association of Computing Machinery's CHI 2011 (Computer Human Interaction) conference in Vancouver -- the premier international conference of Human-Computer Interaction.

Being able to store and interact with documents on larger versions of these light, flexible computers means offices will no longer require paper or printers.

"The paperless office is here. Everything can be stored digitally and you can place these computers on top of each other just like a stack of paper, or throw them around the desk" says Dr. Vertegaal.

The invention heralds a new generation of computers that are super lightweight, thin-film and flexible. They use no power when nobody is interacting with them. When users are reading, they don't feel like they're holding a sheet of glass or metal. -  http://mcaf.ee/um78r

Safety of Nanoparticles in Food Crops Is Still Unclear - ScienceDaily (June 1, 2011) — With the curtain about to rise on a much-anticipated new era of "nanoagriculture" -- using nanotechnology to boost the productivity of plants for food, fuel, and other uses -- scientists are reporting a huge gap in knowledge about the effects of nanoparticles on corn, tomatoes, rice and other food crops.

Their article appears in ACS' Journal of Agricultural and Food Chemistry.

Jorge Gardea-Torresdey, a co-investigator for the NSF/EPA University of California Center for Environmental Implications of Nanotechnology, and colleagues at The University of Texas at El Paso, note that nanoparticles, which are 1/50,000th the width of a human hair, are used in products ranging from medicines to cosmetics. The particles also could end up in the environment, settling in the soil, especially as fertilizers, growth enhancers and other nanoagricultural products hit the market. Some plants can take-up and accumulate nanoparticles. But it is unclear whether this poses a problem for plants or for the animals (like humans) that eat them. So, the researchers sorted through the scientific literature looking for evidence to settle the safety question.

In the article, the scientists analyzed nearly 100 scientific articles on the effects of different types of nanoparticles on edible plants. They found that the uptake and build-up of nanoparticles varies, and these factors largely depend on the type of plant and the size and chemical composition of the nanoparticles. "This literature review has confirmed that knowledge on plant toxicity of [nanomaterials] is at the foundation stage," the article states, noting that the emerging field of nanoecotoxicology is starting to tackle this topic.  -  http://www.sciencedaily.com/releases/2011/06/110601111401.htm

Origami: Between The Folds  -  (Video excerpts - Independent Lens/PBS)  - Origami may seem an unlikely medium for understanding and explaining the world. But around the globe, several fine artists and theoretical scientists are abandoning more conventional career paths to forge lives as modern-day paper folders. Through origami, these offbeat and provocative minds are reshaping ideas of creativity and revealing the relationship between art and science.


BETWEEN THE FOLDS chronicles 10 of their stories. Featuring interviews with and insights into the practice of these intrepid paper folders, the film opens with three of the world's foremost origami artists: a former sculptor in France who folds caricatures in paper rivaling the figures of Daumier and Picasso; a hyper-realist who walked away from a successful physics career to challenge the physics of a folded square instead; and an artisanal papermaker who folds impressionistic creations from the very same medium he makes from scratch.

The film then moves to less conventional artists, exploring concepts of minimalism, deconstruction, process and empiricism. Abstract artists emerge with a greater emphasis on concept, chopping at the fundamental roots of realism, which have long dominated traditional origami. The film also features advanced mathematicians and a remarkable scientist who received a MacArthur Genius Award for his computational origami research.  - http://mcaf.ee/jqkmg

When flower power met quantum theory - (June 27, 2011 - by Marcus Chown - NewScientist) - David Kaiser's How the Hippies Saved Physics is a reminder of the unexpected influence a bunch of freewheeling 1970s physicists had on fundamental theories

a small group of freewheeling physicists who, for four years from May 1975, met regularly in an office at the Lawrence Berkeley National Laboratory in California. "The Fundamental Fysiks Group" was open - perhaps too open - to everything from LSD-tripping, to remote viewing via ESP, to contacting the dead. Its core members, which included physicists Jack Sarfatti, Fred Alan Wolf and Elizabeth Rauscher, even persuaded the great Richard Feynman to attend discussion sessions at the Esalen Institute on the spectacular rocky coast of northern California - though, according to Kaiser, Feynman admitted a big attraction was the "naked co-ed hot-spring baths".  -  http://www.newscientist.com/blogs/culturelab/2011/06/when-flower-power-met-quantum-theory.html

Ultimate Energy Efficiency: Magnetic Microprocessors Could Use Million Times Less Energy Than Today's Silicon Chips - ScienceDaily (July 1, 2011) — Future computers may rely on magnetic microprocessors that consume the least amount of energy allowed by the laws of physics, according to an analysis by University of California, Berkeley, electrical engineers.

Today's silicon-based microprocessor chips rely on electric currents, or moving electrons, that generate a lot of waste heat. But microprocessors employing nanometer-sized bar magnets -- like tiny refrigerator magnets -- for memory, logic and switching operations theoretically would require no moving electrons.

Such chips would dissipate only 18 millielectron volts of energy per operation at room temperature, the minimum allowed by the second law of thermodynamics and called the Landauer limit. That's 1 million times less energy per operation than consumed by today's computers.  -  http://www.sciencedaily.com/releases/2011/07/110701101737.htm

Cling-FilmSolar Cells Could Lead to Advance in Renewable Energy - ScienceDaily (July 4, 2011) — A scientific advance in renewable energy which promises a revolution in the ease and cost of using solar cells, has been announced on July 4, 2011. A new study shows that even when using very simple and inexpensive manufacturing methods -- where flexible layers of material are deposited over large areas like cling-film -- efficient solar cell structures can be made.

The study, published in the journal Advanced Energy Materials, paves the way for new solar cell manufacturing techniques and the promise of developments in renewable solar energy. ….

Plastic (polymer) solar cells are much cheaper to produce than conventional silicon solar cells and have the potential to be produced in large quantities. The study showed that when complex mixtures of molecules in solution are spread onto a surface, like varnishing a table-top, the different molecules separate to the top and bottom of the layer in a way that maximises the efficiency of the resulting solar cell.

Dr Andrew Parnell of the University of Sheffield said, "Our results give important insights into how ultra-cheap solar energy panels for domestic and industrial use can be manufactured on a large scale. Rather than using complex and expensive fabrication methods to create a specific semiconductor nanostructure, high volume printing could be used to produce nano-scale (60 nano-meters) films of solar cells that are over a thousand times thinner than the width of a human hair. These films could then be used to make cost-effective, light and easily transportable plastic solar cell devices such as solar panels."  -  http://www.sciencedaily.com/releases/2011/07/110704082656.htm

"There is a large amount of electromagnetic energy all around us, but nobody has been able to tap into it," said Manos Tentzeris, a professor in the Georgia Tech School of Electrical and Computer Engineering who is leading the research. "We are using an ultra-wideband antenna that lets us exploit a variety of signals in different frequency ranges, giving us greatly increased power-gathering capability."

Tentzeris and his team are using inkjet printers to combine sensors, antennas and energy scavenging capabilities on paper or flexible polymers.
