Pushing the PV Envelope: Organic Solar Cells Moving into Production
July 1, 2008 10:03 AM - , Triple Pundit

Organic photovoltaic cells, including dye-sensitized cells (DSCs) - may be the ultimate when it comes to offering off-grid, micro-power generation. Initial small-scale technology and market tests – solar chargers for mobile phones in Africa, for example - are under way as researchers continue to try to find ways to boost solar energy conversion efficiencies – which now surpass 5% for small organic PV cells and up to 11% for DSCs - minimize production costs and develop markets for both small- and large-scale applications.

Toyota to build Camry hybrids in China in 2010: paper
July 1, 2008 09:18 AM - Reuters

TOKYO (Reuters) - Toyota Motor Corp plans to begin building and selling a hybrid version of its Camry sedan in China in 2010 in anticipation of growing demand for environmentally friendly vehicles, the Nikkei business daily reported on Tuesday.

Global Warming to Melt North Pole Ice Cover For First Time in Recorded History
June 30, 2008 10:18 AM -

After last year's thin ice cover, the North Pole is poised to vanish due to global warming in a short time DailyTech has previously covered the frantic pace of melt in Greenland, which is accelerating, dumping vast amounts of water into the sea. Meanwhile, the North Pole has been steadily melting away as well. Fortunately, the North Pole ice is floating, and thus will not affect sea levels, but its dissolution is an important indicator of warming.

Smart camera keeps an eye on rare penguins
June 30, 2008 08:43 AM - New Scientist

You may think penguins all look the same, but a computer system on a South African island knows better. It can identify individual birds from subtle differences in their plumage. The technology could help researchers monitor threatened populations without using more invasive methods that can distress or harm the birds.

Ancient Oak Trees Help Reduce Global Warming
June 30, 2008 08:37 AM - University of Missouri

The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for thousands of years, a significantly longer period of time than trees that fall in a forest, thus keeping carbon out of the atmosphere.

Brown researchers create mercury-absorbent container linings for broken CFLs
June 27, 2008 10:11 AM - Brown University

With rising energy prices and greater concern over global warming, compact fluorescent lamps (CFLs) are having a successful run. Sales of the curlicue, energy-sipping bulbs, which previously had languished since they were introduced in the United States in 1979, reached nearly 300 million last year. Experts expect that figure to rise steeply by 2012, when a federal law requiring energy-efficient lighting goes into effect.

Martian soil appears able to support life
June 27, 2008 09:43 AM - Reuters

"Flabbergasted" NASA scientists said on Thursday that Martian soil appeared to contain the requirements to support life, although more work would be needed to prove it. Scientists working on the Phoenix Mars Lander mission, which has already found ice on the planet, said preliminary analysis by the lander's instruments on a sample of soil scooped up by the spacecraft's robotic arm had shown it to be much more alkaline than expected.

Major technological progress needed to make renewable energy affordable.
June 25, 2008 10:50 AM - ENN

Dramatic progress in renewable energy technology is needed if the United States desires to produce 25 percent of its electricity and motor vehicle fuel from renewable sources by 2025 without significantly increasing consumer costs, according to a RAND Corporation study issued today.

Looming tropical disaster needs urgent action
June 25, 2008 09:56 AM - The University of Adelaide

A major review by University of Adelaide researchers shows that the world is losing the battle over tropical habitat loss with potentially disastrous implications for biodiversity and human well-being. Published online today in the Ecological Society of America's journal Frontiers in Ecology and the Environment, the review concludes we are "on a trajectory towards disaster" and calls for an immediate global, multi-pronged conservation approach to avert the worst outcomes.

Scientists Are Developing Alloy Based Fridges Running On 50% Less Energy
June 25, 2008 09:50 AM - , Triple Pundit

European researchers say they have begun to develop fridges that are powered by a 100% alloy which will reduce their energy usage by 50%. In the last 15 years, fridge technology developers have had to consider what option would be the lesser of two evils. Environmentalists alerted them to the harmful side effects of chlorofluorocarbons (CFCs), the refrigerant chemical, but alternative refrigerants require a lot more energy.
