Flat out wrong. That's what a team of Duke researchers has discovered, much to its surprise, about a long-accepted explanation of how nuclei collide to produce charged particles for electricity - a process receiving intense interest lately from scientists, entrepreneurs and policy makers in the wake of Japan's nuclear crisis.

One of the most important decisions facing designers of plug-in electric or hybrid vehicles is related to battery choice. Now, researchers at the Norwegian University of Science and Technology (NTNU) have used a life cycle analysis to examine three vehicle battery types to determine which does the best job of powering the vehicle while causing the least amount of environmental impact during its production.

Two professors from the University of Illinois; one specializing in materials science, the other in electrical engineering, have combined their talents to take the idea of printing circuits onto non-standard materials one step further by developing a conductive ink that can be used in a traditional rollerball ink pen to draw circuits by hand onto paper and other porous materials. In their paper published in Advanced Materials, team leads Jennifer Lewis, Jennifer Bernhard and colleagues describe how they were able to make a type of ink from silver nanoparticles that would remain a liquid while in the pen, but would dry like regular ink once applied. The pen could was then used to draw a functioning LCD display and an antenna.

The European Union nation of 1.3 million generates 97 percent of its electricity thanks to oil shale -- sediment formed 400-450 million years ago, containing hydrocarbons. Its industry forecasts that shale's use can only expand.

Much of what we write about here at GeekMom is high tech gadgetry, so when I say 'solar' you might think of any number of modern solar powered electrical systems. What you probably didn't think about is the super low tech but incredibly brilliant solar bottle bulb developed by students from the Massachusetts Institute of Technology (MIT).

In a country where nearly 40 percent of households have no electricity, any new advancement that will help bring power to the world's second most populous nation, must be met with celebration and open arms.

We're stumbling through a science fiction wonderland of not just high-flying communications software and tools but of the basic building blocks for the devices we use to do that communicating. The latest contender for radically-improved memory in a computer? Blood. Researchers in Gujarat, India have created a "memristor" -- a portmanteau of memory and resistor -- made of human blood. A resistor is the part of a computer chip that regulates the flow of electricity. Unlike most resistors, a memristor remembers previous levels of voltage and allows for a repeat of that flow.

Conventional silicon-based rigid solar cells generally found on the market are not suitable for manufacturing moldable thin-film solar cells, in which a transparent, flexible and electrically conductive electrode collects the light and carries away the current. A woven polymer electrode developed by Empa has now produced first results which are very promising, indicating that the new material may be a substitute for indium tin oxide coatings.

In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research, published online this week in the journal Nature Nanotechnology, is based on findings that carbon nanotubes - microscopic, hollow cylinders of pure carbon - can enhance the efficiency of electron collection from a solar cell's surface.

Along with China's rise as a world economic power have come a rapid climb in energy use and a related boost in man-made carbon dioxide emissions. In fact, China overtook the United States in 2007 as the world's leading emitter of greenhouse gases. Yet according to this new forecast, the steeply rising curve of energy demand in China will begin to moderate between 2030 and 2035 and flatten thereafter. There will come a time-within the next two decades-when the number of people in China acquiring cars, larger homes, and other accouterments of industrialized societies will peak. It's a phenomenon known as saturation. "Once nearly every household owns a refrigerator, a washing machine, air conditioners and other appliances, and once housing area per capita has stabilized, per household electricity growth will slow,'' Levine explains.

Imagine a world where the windows of high-rise office buildings are powerful energy producers, offering its inhabitants much more than some fresh air, light and a view.

A team of researchers, led by Dr. Yi Cui, of Stanford and Dr. Bruce Logan from Penn State University have succeeded in developing an entropy battery that pulls energy from the imbalance of salinity in fresh water and seawater. Their paper, published in Nano Letters, describes a deceptively simple process whereby an entropy battery is used to capture the energy that is naturally released when river water flows into the sea.

In his talk on Deep Optimism, Ridley presented a coherent, integrated, and astoundingly thorough case for progress in all degrees. For one easy-to-visual metric, Ridley showed how it takes less time each year to work for a constant benefit, say on hour of artificial light at night. It 1800 it took six hours of typical labor to purchase an hour's worth of candles, so few working people did. In 1880 it took fifteen minutes of work to purchase an hour's worth of kerosene for a lamp. In 1950 it took eight seconds of work to pay for an hour's electricity for a light bulb. In 1997, it took only half a second -- a blink -- of work to light a compact fluorescent bulb for an hour.

Fast, low-energy memory for MP3s, smartphones and cameras could become a reality thanks to University of Edinburgh scientists.
