• The future of solar-powered houses is clear

    Transparent glass containing solar cells could capture enough energy to power a home Professor John Bell said QUT had worked with a Canberra-based company Dyesol, which is developing transparent solar cells that act as both windows and energy generators in houses or commercial buildings. >> Read the Full Article
  • Carbon Nanotubes Made Into Conductive, Flexible 'Stained Glass'

    Carbon nanotubes are promising materials for many high-technology applications due to their exceptional mechanical, thermal, chemical, optical and electrical properties. Now researchers at Northwestern University have used metallic nanotubes to make thin films that are semitransparent, highly conductive, flexible and come in a variety of colors, with an appearance similar to stained glass. These results, published online in the journal Nano Letters, could lead to improved high-tech products such as flat-panel displays and solar cells. >> Read the Full Article
  • Green phones still a few years away: Nokia

    HELSINKI (Reuters) - Cellphones from recycled materials are a few years away from reaching consumers' hands, a senior official at Nokia said on Thursday, adding the handset maker expects the green push will boost demand. "We believe it will become a competitive factor," Markus Terho, a director at Nokia's environmental affairs unit, told a news conference. >> Read the Full Article
  • Climate assumptions 'optimistic at best'

    The UN Intergovernmental Panel on Climate Change (IPCC) has seriously underestimated the technological advances needed to stem carbon dioxide emissions, say Roger Pielke Jr, Tom Wigley and Christopher Green in Nature. They describe the IPCC's assumption that the majority of future emission reductions will occur spontaneously, in the absence of climate policies, as "optimistic at best and unachievable at worst". >> Read the Full Article
  • New MIT Start-up Aims to Make Silicon Solar Cells Competitive With Coal

    1366 Technologies, a new MIT start-up aiming to make silicon solar cells competitive with coal, today announced it has secured $12,4 million in a first round of financing co-led by North Bridge Venture Partners and Polaris Venture Partners. MIT Professor, 1366 founder and CTO, Ely Sachs, noted that 1366 Technologies will be combining innovations in silicon cell architecture with manufacturing process improvements to bring multi-crystalline silicon solar cells to cost parity with coal-based electricity. >> Read the Full Article
  • Cow stomach holds key to turning corn into biofuel

    An enzyme from a microbe that lives inside a cow’s stomach is the key to turning corn plants into fuel, according to Michigan State University scientists. The enzyme that allows a cow to digest grasses and other plant fibers can be used to turn other plant fibers into simple sugars. These simple sugars can be used to produce ethanol to power cars and trucks. >> Read the Full Article
  • World’s Largest Tidal Turbine Successfully Installed

    The world’s largest tidal turbine, weighing 1000 tonnes, has been installed in Northern Ireland’s Strangford Lough. The tidal turbine is rated at 1.2 megawatts, which is enough to power a thousand local homes. It was built by Marine Current Turbines, and it will be the first commercial tidal turbine to produce energy, when it begins operation later this year. The turbine has twin rotors measuring 16 meters in diameter. The rotors will operate for up to 18-20 hours per day to produce enough clean, green electricity. >> Read the Full Article
  • Robots seen doing work of 3.5 million people in Japan

    TOKYO (Reuters) - Robots could fill the jobs of 3.5 million people in grayingJapan by 2025, a thinktank says, helping to avert worker shortages as the country's population shrinks. Japan faces a 16 percent slide in the size of its workforce by 2030 while the number of elderly will mushroom, the government estimates, raising worries about who will do the work in a country unused to, and unwilling to contemplate, large-scale immigration. >> Read the Full Article
  • No end in site for animal cloning moratorium: USDA

    WASHINGTON (Reuters) - The U.S. Agriculture Department said on Monday it will not lift a voluntary moratorium on selling meat and milk from cloned animals to consumers any time soon. In January, the U.S. Food and Drug Administration ruled that products from cloned cattle, swine and goats and their offspring were as safe as milk and meat from traditional animals. >> Read the Full Article
  • Dell Headquarters Powered With Green Energy

    It was announced yesterday that Dell Computer’s 2.1 million-square-foot headquarters in Round Rock, Texas is now powered entirely with renewable energy. 60% of the energy is supplied by wind power generated by Energy Future Holdings Corp.’s TXU Energy and the remaining 40% from Waste Management’s landfill gas-to-energy plant. Dell, a participant in Austin Energy’s GreenChoice® power program, also announced it is increasing it’s renewable energy at its Austin Parmer Campus from 8 to 17%. >> Read the Full Article
