Zap of Electricity Through Your Brain Can Boost Math Skills

brain-lightning

The technique may help people with dyscalculia, or “number blindness” in the future.

Pulsing an electrical current through your brain can boost your ability to do sums for up to six months, scientists have discovered.  British-based researchers have found that passing a low current through a specific brain region can double your ability to do mathematics.

Power-Generating Windows!(Transparent Conductive Material)

possible with conjugated polymer (PPV) honeycomb technology

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Los Alamos National Laboratory have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. The material, described in the journal Chemistry of Materials, could be used to develop transparent solar panels or even windows that absorb solar energy to generate electricity.

Windstalk – Wind Farm Without the Turbines

Windstalk

Wind turbines are an increasingly popular way to generate clean energy with large-scale wind farms springing up all over the world. However, many residents near proposed wind farm sites have raised concerns over the aesthetics and the low frequency vibrations they claim are generated by wind turbines. An interesting Windstalk concept devised by New York design firm Atelier DNA could overcome both these problems while still allowing a comparable amount of electricity to be generated by the wind.

World’s Biggest Offshore Wind Farm to be Switched On

wind turbine 1

There are more than 100 giant turbines in the Thanet wind farm.

Arranged in formation like an advancing army, this is the world’s biggest offshore wind farm.  The array of more than 100 giant turbines towering over the North Sea will be switched on today off the coast of Kent.

Cell phones could be powered just by talking.

Chatty teenagers could be the world’s next renewable energy source.  A new nanomaterial can convert sound waves into electricity. The technology could be applied to cell phone or loud, busy highways to generate power.

Europe to Reduce Power to Vacuum Cleaners to Cut Energy Use

VacuumingCarpet

The cleanliness of Britain’s homes is being threatened by European bureaucrats. 

First it was traditional light bulbs, then it was plasma televisions. Now European bureaucrats are targeting the nation’s vacuum cleaners as part of plans to cut energy use in the home.  Officials at the European Commission are proposing to restrict the power of domestic vacuum cleaners in a move which experts fear could reduce their effectiveness in sucking up dust and dirt.

Self-Assembling Solar Cells Created That Repair Themselves

MIT’s Test Cell

Solar cells are intended to mimic the photosynthesis of plants — converting light into energy in the most efficient manner possible. But what other characteristics of plants could be handy for the renewable energy sector to mimic? How about the self-assembly of chloroplast, the component of plants that do all the vital photosynthesis. Leaves repair themselves after sun damage again and again to keep up their ability to convert light into energy. Now, MIT researchers believe they’ve discovered how to use this self-assembly to restore solar cells damaged by the sun.

Next Big Power Source? Pulling Electricity Out of Thin Air

lightning storm

“Hygroelectricity,” meaning “humid electricity” could be the next big power source.

We’re already making great strides at pulling electricity from the motion of the air and from the photons that stream through it, but what about pulling electric charges right out of the air itself? Researchers have solved a mystery about how electricity forms in the atmosphere, and in doing so may have found a way to pull electricity right out of the air.

China to Shut Down 2,000 Factories to Meet Their Energy-Efficiency Goals

10yuan

Coal has made China the world’s largest emitter of greenhouse gases.

Earlier this summer, Prime Minister Wen Jiabao of China promised to use an “iron hand” to improve his country’s energy efficiency, and a growing number of businesses are now discovering that it feels like a fist.  The Ministry of Industry and Information Technology quietly published a list late Sunday of 2,087 steel mills, cement works and other energy-intensive factories required to close by Sept. 30.

New Solar Cells Can Produce Electricity From Light and Heat Simultaneously

light and heat

A small PETE device made with cesium-coated gallium nitride glows while being tested inside an ultra-high vacuum chamber.

Though the sun offers us a couple options for exploiting its energy — light and heat — we’ve always had to choose to use one at a time, because solar-energy technology hasn’t been able to capture both typs of radiation simultaneously. Stanford researchers say that’s about to change, however. Their new breakthrough could put solar power on par with oil, price-wise. (Video)

Wind Lens Floating Farms Could Boost Electricity Production in Japan

Future wind-turbine farms

The Yokohama Renewable Energy International Exhibition 2010 earlier this month revealed some visually spectacular new designs for wind turbine technology. The Wind Lens has the potential to triple the amount of electricity produced by offshore turbines according to experiments. Kyushu University professor Yuji Ohya spoke of the merits of the 112-meter diameter structures being able to increase energy output “two or three fold”, as well as being about to reduce the dreaded noise pollution so often associated with wind turbines, and improve safety too.
