Organic Photovoltaics - Forecasts for the Next Decade

Today there are multiple devices available for harnessing solar energy. Each device offers a different set of characteristics. Wafer-based devices consist of mono or polycrystalline and are the most mature technology due to the experience borrowed from the microelectronics industry.

Cool and Green: Vehicle Thermal Management

Air conditioning is a ‘must-have’ for most new cars. But the fluorocarbon refrigerant HFC-134a – the global standard – is one of the ozone-depleting greenhouse gases causing global warming. With these concerns, the European Union has passed regulations phasing out the compound beginning in 2011 and mandating the use of alternatives with less environmental impact.

Revolution in Fasteners Helps Bridge the Gap 
to Greener Vehicles

With auto sales down as much as 40 percent, it can feel to some like the industry is coming apart. But a "revolution in fasteners" may soon help bridge the gap to greener vehicles, while increasing sales and lowering recall and warranty rates.

Power Conversion for Reduced Cost, Volume, and Weight - and Increased Efficiency

Industry and consumers are increasingly aware of the benefits of efficacious use of metered power, as costs and cost trends increase. Making the right choices for power converter design can produce rapid investment payback in applications such as for LED illumination and automotive electric vehicles, and can be optimized for low total cost of ownership (TCO).

Development of a Centrifugal Hydrogen Pipeline Gas Compressor

DOE has prepared a Multi-Year Research, Development, and Demonstration Plan to provide hydrogen as a viable fuel for transportation after 2020, and commissioned Concepts NREC (CN) with the project of developing a centrifugal hydrogen pipeline gas compressor. Phase I of this project has been completed and is described in this article.

Windshields to Reflect Sunlight, and Perhaps Produce Electricity

The California Air Resources Board will require new cars sold in California to have windows that reflect or absorb heat-producing rays from the sun. Starting in 2012, windows must prevent 45 percent of the sun's total heat-producing energy from entering the car, and the windshield must reject at least 50 percent. In 2016, this increases to 60 percent.

Lithium-Ion Batteries Fuel the Future of Automotive Design

In 1924, General Motors president Alfred P. Sloan Jr. devised annual model-year design changes in order to maintain unit sales. Body shapes faced cosmetic changes every year, whether or not the underlying automobile had changed. This breakthrough strategy had widespread effects on the automobile business, automotive design, and eventually the United States economy. In recent years, amongst a worsening economy and a struggling auto industry, the underlying automobile has changed rapidly, with emphases on efficiency and environmental friendliness.
