Technology Review: Record Efficiency for Plastic Solar Cells - 0 views

  • Until now, however, the tandem architecture spoiled plastic photovoltaics such as Heeger's, which are "printed" by spraying solutions of conductive plastics and other materials onto a plastic film.

IBM, Harvard Launch Distributed-Computing Search for Super-Efficient Solar Cells - 0 views

  •  
    IBM and researchers from Harvard University launched a joint effort today to identify more efficient and lower-cost solar cell materials using distributed computing. Leveraging small amounts of computing power from potentially hundreds of thousands of personal computers, this latest addition to the company's World Community Grid platform will process more than 1 million configurations of atoms over the next two years in search of an organic molecule that can be used to make materials for an ultra-efficient plastic photovoltaic cell.

Green Technology Breakthrough - Inkjet Printed Solar Cells - 0 views

  • In an advancement that could radically reduce the cost of making solar panels, Massachusetts-based Konarka Technologies has developed and successfully demonstrated the ability to print solar cells with an inkjet printer. By using the inkjet printing process in the manufacturing of solar cells, the need for “clean rooms” is eliminated, and manufacturers can work with a number of different substrates, including plastics, and different colors.

Solar Ivy Nears Commercial Availability - 2 views

  • Sustainable design start-up SMIT has been working on solar and wind powered facade technology for a while under the GROW moniker.  Now, the company is about to blow the lid off the solar-powered GROW with commercial availability.  SMIT is using a new name and website, Solar Ivy, for the biomimicry-inspired innovation made with recyclable polyethylene leaves, Konarka Power Plastic organic photovoltaics, and a structural stainless steel mesh system.

Paper Or Plastic? - Forbes.com - 0 views

  •  
    In the past six months, flat-screen plasma televisions have accounted for nearly half of all TVs sold around the world. During the manufacturing process, plasma televisions release a gas called nitrogen trifluoride, or NF3, which does approximately 17,000 times more environmental damage than carbon dioxide. But because NF3 was not widely used when the Kyoto protocol was created, it is not classified and controlled as a harmful gas--so even though we've tightened the belt and reduced some emissions, we've missed new ones that are making things far worse.

Global sustainability and key needs in future automotive design - 0 views

  •  
    Environ Sci Technol. 2003 Dec 1;37(23):5414-6. Global sustainability and key needs in future automotive design. McAuley JW. Basell USA Inc., 912 Appleton Road, Elkton, Maryland 21921, USA. john.mcauley@basell.com Abstract The number of light vehicle registrations is forecast to increase worldwide by a factor of 3-5 over the next 50 years. This will dramatically increase environmental impacts worldwide of automobiles and light trucks. If light vehicles are to be environmentally sustainable globally, the automotive industry must implement fundamental changes in future automotive design. Important factors in assessing automobile design needs include fuel economy and reduced emissions. Many design parameters can impact vehicle air emissions and energy consumption including alternative fuel or engine technologies, rolling resistance, aerodynamics, drive train design, friction, and vehicle weight. Of these, vehicle weight is key and will translate into reduced energy demand across all energy distribution elements. A new class of vehicles is needed that combines ultra-light design with a likely hybrid or fuel cell engine technology. This could increase efficiency by a factor of 3-5 and reduce air emissions as well. Advanced lightweight materials, such as plastics or composites, will need to overtake the present metal-based infrastructure. Incorporating design features to facilitate end-of-life recycling and recovery is also important. The trend will be towards fewer materials and parts in vehicle design, combined with ease of disassembly. Mono-material construction can create vehicle design with improved recyclability as well as reduced numbers of parts and weight.

Flexible nanoantenna arrays capture abundant solar energy - 0 views

  •  
    Researchers have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. The technology, developed at the U.S. Department of Energy's Idaho National Laboratory, is the first step toward a solar energy collector that could be mass-produced on flexible materials.

The Energy Blog: Microwave Process Converts Waste Materials into Oil and Gas - 0 views

  • Global Resource Corporation (GRC) (OTC: GBRC.PK) claims that its HAWK 10 high-frequency microwave recycling process can recover oil and gases from oil shale, residual oil, drill cuttings, tar sands oil, contaminated dredge/sediments, tires and  plastics with significantly greater yields and lower costs than are available utilizing existing known technologies.

Here comes the flow battery | Tech news blog - CNET News.com - 0 views

  •  
    What is a flow battery? It's a battery with tanks of electrolytes that effectively lets the battery store more energy than normal batteries. The electrolyte flows or circulates through the system. The larger the tanks, the more electricity it can store. "They are cheaply made out of plastic. They are low maintenance," said Rick Winter, an executive at Deeya Energy, which makes flow batteries. The company has been busy this summer setting up manufacturing facilities in India

Chemists Break Down Pesky Greenhouse Gas (Wired.com) - 0 views

  •  
    The molecules, known as fluorocarbons, are found in plastics, clothing and refrigerants. At their heart is a union of carbon and fluorine -- a union that, thanks to their atomic configurations, is one of the strongest molecular unions known in nature. Under standard conditions, fluorocarbons are impervious to acids and bases. They don't give or receive electrons, the very currency of molecular reconfiguration. Breaking them down is possible only at temperatures approaching 2000 degrees Fahrenheit. In some situations, that stability is a blessing: Teflon is made from fluorocarbons. But so are the hydrofluorocarbon coolants in refrigerators and air conditioners -- and when released, those become greenhouse gases that can circulate for thousands of years.
