A new printable battery that can be produced cost-effectively on a large scale has been developed by a research team led by Prof. Dr. Reinhard Baumann of the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz together with colleagues from TU Chemnitz and Menippos GmbH.

Like your t-shirt, the batteries are printed using a silk-screen method.

They are also different from conventional batteries in that these printable versions weigh less than one gram, are less than a millimeter thick and can even be integrated into bank cards.

As a kid, there were few things more satisfying to me that being given a helium balloon... and then almost immediately letting it go for the pure enjoyment of seeing it float out of sight into the sky. For some reason, seeing a small balloon set against a vast blue background gave me a small sense of power simply from knowing that I was the one that put it up there. A silly grin would spread across my face as I stared at the small dot in the sky, knowing that only a minute earlier I held that very same balloon in my own little hand. I felt like a small part of me was launched along with it, and had just started off on a grand adventure. Since I was never able to actually go along for the ride, it was up to the limits of my imagination to envision where the balloon would land.

   Its my opinion that the current economic conditions were brought on by high gas prices. I believe if we can consume less fuel we can stabilize the price of gasoline and our economy. If we do nothing we will have contributed to our failing economy. Here is a solution we can implement right now, saving money and improving our economy.
   I have doubled my gas mileage. If you have improved your mileage and want to share your designs or ideas please post. If you are an idiot and think it is impossible to improve gasoline mileage don't waste our time.

An international team of researchers has modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria. The team was then able to determine the structure of these light antennae. This is the first step to converting sunlight into energy using an artificial leaf.

Leiden researcher Swapna Ganapathy has obtained her PhD based on this subject, under the supervision of Professor Huub de Groot, one of the initiators of the research.

University of Georgia researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs.

UGA chemist Jason Locklin and graduate students Nicholas Marshall and Kyle Sontag grew polymer brushes, made up of chains of thiophene and benzene, aromatic molecules sometimes used as solvents, attached to metal surfaces as ultra-thin films.

Feeling increasingly uncomfortable on this blog, as it seems to be becoming an outlet for the Anti-God Squad, I nevertheless want to share with my friends this interesting news item which I first spotted in the Times of India Health&Science Section, where it was headlined

Cabbage fuel reduces carbon release.
WASHINGTON: Jet fuel's grave carbon emissions can be reduced by about 84 per cent by refining it from the seeds of a lowly weed, which is a cousin to the cabbage, says a Michigan Technological University researcher.

In revisiting a chemical reaction that's been in the literature for several decades and adding a new wrinkle of their own, researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it can be effectively industrialized, could allow many of today's petrochemical products, including plastics, to instead be made from biomass. 

"We've found and optimized a selective, one-pot deoxygenation technique based on a formic acid treatment," said Robert Bergman, a co-principal investigator on this project who holds a joint appointment with Berkeley Lab's Chemical Sciences Division and the UC Berkeley Chemistry Department.

Like ethanol, the darling of activists who refused to know any better until it was actually implemented and shown to be a disaster, there is a certain amount of marketing hype around CFL bulbs and environmental groups have drunk the Kool-Aid.  

All mercury is bad when it comes to kids.   And who knows what those frequencies will do to your pets?   But it may not be an issue for long.   A new laser process says it can double the brightness of incandescent bulbs while using the same amount of energy.

A new study carried out at the University of Leicester reveals that an alternative to oil could be found in ancient sea deposits dating to 300 million years ago.

Shale gas sourced in mudstones in shallow water seaways could provide the future alternative to fuel modern society in the wake of demands to find new energy sources, according to the doctoral research.

These mudstones, now exposed across central and northern England, contain up to 14% carbon.

A new type of air-fuelled battery called the STAIR (St Andrews Air) cell could give up to ten times the energy storage of designs currently available, meaning a new generation of batteries for electric cars, mobile phones and laptops.

The new design has the potential to improve the performance of portable electronic products and give a major boost to the renewable energy industry. The batteries will enable a constant electrical output from sources such as wind or solar, which stop generating when the weather changes or night falls.

In Finland, leaders in various fields have taken up the challenge presented by the increasing use of natural resources. Jointly, they have set out to find an answer to the question of how to use natural resources to enhance both national competitiveness and global responsibility. One result of this cooperation is the Natural Resource Strategy for Finland, a unique effort on a global scale.

Scientists in California are reporting use of a first-of-its-kind approach to craft genetically engineered microbes with the much-sought ability to transform switchgrass, corn cobs, and other organic materials into methyl halides — the raw material for making gasoline and a host of other commercially important products.

The new bioprocess could help pave the way for producing biofuels from agricultural waste, easing concerns about stress on the global food supply from using corn and other food crops. Their study is scheduled for the May 20 issue of the Journal of the American Chemical Society

Rising shale gas production in the United States and Canada as well as potential natural gas supplies from Iraq could be pivotal in curbing Russia's ability to organize an "energy weapon" against European consumers, according to a new study released today by Rice University's Baker Institute for Public Policy. 

The study, "Russia and the Caspian Basin in the World Energy Balance," examines Russia's evolving energy relations with its Caspian neighbors, the Organization of Petroleum Exporting Countries and the West and considers potential scenarios for Russian and Caspian oil and natural gas strategies.

Biofuels such as ethanol offer an alternative to petroleum for powering our cars, but growing energy crops to produce them can compete with food crops for farmland, and clearing forests to expand farmland will aggravate the climate change problem. How can we maximize our "miles per acre" from biomass?

Researchers writing in Science magazine say the best bet is to convert the biomass to electricity, rather than ethanol. They calculate that, compared to ethanol used for internal combustion engines, bioelectricity used for battery-powered vehicles would deliver an average of 80% more miles of transportation per acre of crops, while also providing double the greenhouse gas offsets to mitigate climate change.

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.

A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered that a residue of a process used to build arrays of titania nanotubes (that wasn’t even previously noticed), plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas from water. Their results indicate that by controlling the deposition of potassium on the surface of the nanotubes, engineers can achieve significant energy savings in a promising new alternate energy system.

Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a cost-effective and energy-efficient strategy for turning biomass into alternative fuels.

In separate papers published today in Biophysical Journal and recently in an issue of Biomacromolecules, Los Alamos researchers identify potential weaknesses among sheets of cellulose molecules comprising lignocellulosic biomass, the inedible fibrous material derived from plant cell walls. The material is a potentially abundant source of sugar that can be used to brew batches of methanol or butanol, which show potential as biofuels.

Engineers at Oregon State University say they have discovered a way to use ancient life forms, diatoms, to create one of the newest technologies for solar energy - systems that may be surprisingly simple to build compared to existing silicon-based solar cells.

Diatoms are tiny, single-celled marine life forms have existed for at least 100 million years and are the basis for much of the life in the oceans, but they also have rigid shells that can be used to create order in a natural way at the extraordinarily small level of nanotechnology.   They are also a key part of the marine food chain and help cycle carbon dioxide from the atmosphere.
