Developing sustainable power

Posted: 28 Feb 2012 09:39 AM PST Scientists suggest that renewable energy is a viable option for electrical power in developing and emerging nations. Researchers point out that in most of these nations, the demand for energy far exceeds the generating capacity.

Reduction in U.S. carbon emissions attributed to cheaper natural gas

Lower emission from power plants in 2009 was driven by competitive pricing of natural gas versus coal, researchers say.

• Replacing electricity with light: First physical 'metatronic' circuit created
• More powerful electric cars: Mechanism behind capacitor's high-speed energy storage discovered
• Aircraft of the future could capture and re-use some of their own power
• Energy harvesting: Wringing more energy out of everyday motions

Replacing electricity with light: First physical 'metatronic' circuit created Posted: 23 Feb 2012 03:38 PM PST The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers are pushing circuitry forward in a different way, by replacing electricity with light.

More powerful electric cars: Mechanism behind capacitor's high-speed energy storage discovered Posted: 23 Feb 2012 03:26 PM PST Researchers have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars.

Aircraft of the future could capture and re-use some of their own power Posted: 23 Feb 2012 10:33 AM PST Tomorrow's aircraft could contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity. They could use this to power their taxiing to and from airport buildings, reducing the need to use their jet engines. This would save on aviation fuel, cut emissions and reduce noise pollution at airports.

Energy harvesting: Wringing more energy out of everyday motions Posted: 21 Feb 2012 12:14 PM PST Randomness and chaos in nature, as it turns out, can be a good thing -- especially when trying to harvest energy from the movements of everyday activities. Engineers believe they have come up with the theoretical underpinning that could lead to the development of energy harvesting devices that are not only more versatile than those in use today, but should be able to wring out more electricity from the motions of life.

• Tiny, implantable medical device can propel itself through bloodstream
• New twist on nanowires: Technology can control composition and structure of these tiny wires as they grow
• Recharge your cell phone with a touch? New nanotechnology converts body heat into power

Tiny, implantable medical device can propel itself through bloodstream Posted: 22 Feb 2012 06:42 AM PST For 50 years, scientists had searched for the secret to making tiny implantable devices that could travel through the bloodstream. Engineers have now demonstrated a wirelessly powered device that just may make the dream a reality.

New twist on nanowires: Technology can control composition and structure of these tiny wires as they grow Posted: 22 Feb 2012 06:42 AM PST Nanowires -- microscopic fibers that can be "grown" in the lab -- are a hot research topic today, with a variety of potential applications including light-emitting diodes and sensors. Now, researchers has found a way of precisely controlling the width and composition of these tiny strands as they grow, making it possible to grow complex structures that are optimally designed for particular applications.

Recharge your cell phone with a touch? New nanotechnology converts body heat into power Posted: 22 Feb 2012 06:29 AM PST Never get stranded with a dead cell phone again. A promising new technology called Power Felt, a thermoelectric device that converts body heat into an electrical current, soon could create enough juice to make another call simply by touching it.

Superbugs from space offer new source of power Posted: 21 Feb 2012 06:26 PM PST Scientists have created a "designer slime" that can double the electrical output of existing microbial fuel cells. Bacillus stratosphericus -- a microbe commonly found in high concentrations in the stratosphere orbiting Earth with the satellites -- is a key component of a new 'super' biofilm.

Dubai: The Adventure Never Stops

Mentor Series - Worldwide Photo Treks

Click here to View Online

HANDS ON LEARNING • EXCLUSIVE PHOTO OPS • DIGITAL REVIEW SESSIONS The adventure never stops, especially when we travel to the Arabian desert. Explore the dunes on an off-road vehicle and take in a camel caravan against the arid landscape as the sun sets. Enjoy a Bedouin dinner in the desert, complete with a belly dancer. A day trip to the East Coast takes us through spectacular mountain scenery, a local market, a picturesque fishing village, and lunch by the Indian Ocean. We will end this exciting trek on a high note-literally!-with an early morning hot-air-balloon ride, photographing from high above as the sun greets the desert landscape. Mentors: Michael Clark & David Tejada

Only the lowest carbon dioxide emitting technologies can avoid a hot end-of-century Posted: 16 Feb 2012 06:50 AM PST Could replacing coal-fired electricity plants with generators fueled by natural gas bring global warming to a halt in this century? What about rapid construction of massive numbers of solar or wind farms, hydroelectric dams, or nuclear reactors -- or the invention of new technology for capturing the carbon dioxide produced by fossil-fueled power plants and storing it permanently underground? A research team calculated the expected climate effects of replacing the world's supply of electricity from coal plants with any of eight cleaner options.
