Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.

Lately it has become a matter of conventional wisdom that hydrogen will solve many of our energy and environmental problems. Nearly everyone -- environmentalists, mainstream media commentators, industry analysts, General Motors, and even President Bush -- seems to expect emission-free hydrogen fuel cells to ride to the rescue in a matter of years, or at most a decade or two. Not so fast, says Joseph Romm. In The Hype about Hydrogen, he explains why hydrogen isn't the quick technological fix it's cracked up to be, and why cheering for fuel cells to sweep the market is not a viable strategy for combating climate change. Buildings and factories powered by fuel cells may indeed become common after 2010, Joseph Romm argues, but when it comes to transportation, the biggest source of greenhouse-gas emissions, hydrogen is unlikely to have a significant impact before 2050. The Hype about Hydrogen offers a hype-free explanation of hydrogen and fuel cell technologies, takes a hard look at the practical difficulties of transitioning to a hydrogen economy, and reveals why, given increasingly strong evidence of the gravity of climate change, neither government policy nor business investment should be based on the belief that hydrogen cars will have meaningful commercial success in the near or medium term. Romm, who helped run the federal government's program on hydrogen and fuel cells during the Clinton administration, provides a provocative primer on the politics, business, and technology of hydrogen and climate protection.

When Dan set out to drive his Jeep from the Northern tip of Alaska to Tierra del Fuego on the Southern tip of South America, he had no idea how much the adventure would change his life. Over the course of two years, Dan's expedition spanned forty thousand miles through sixteen countries. Now he will never be the same. After years of saving, dreaming and planning, Dan wanted to find out if an ordinary guy can achieve the extraordinary. With no sponsorship, a modest savings account and a willingness to learn Spanish, Dan threw himself in. Going solo, with no GPS and sleeping in a ground tent, Dan wanted to experience everything the Americas have to offer. From poking lava with a stick and hiking among world-famous mountains to corrupt military and camping with Ecuadorian locals - every day provided something new. With his eyes and ears open to the world around him, Dan met many interesting and thought-provoking characters. With their guidance and prodding, and by using their unique perspective, Dan was able to learn many valuable life lessons. Running to the beat of a different drum, Latin America was the perfect classroom for Dan to view our modern work-a-day world through an entirely new lens.

The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.

This volume contains a unique compilation of research and reflections representing multiple vantage points stemming from different parts of the world that can help science educators and teacher educators in finding ways to meaningfully and purposefully embed sustainability into teaching and learning. It is a rich resource for exploring and contextualizing sustainability-oriented science education. At this time we find ourselves in a situation in which the earth’s ecological system is under significant strain as a result of human activity. In the developed world people are asking “How can we maintain our current standard of living?” while those in the developing world are asking “How can we increase the quality of our lives?” all while trying to do what is necessary to mitigate the environmental problems. This volume responds to these questions with a focus on educating for sustainability, including historical and philosophical analyses, and pedagogical and practical applications in the context of science teacher preparation. Included are many examples of ways to educate science teachers for sustainability from authors across the globe. This text argues that issues of sustainability are increasingly important to our natural world, built world, national and international economics and of course the political world. The ideas presented in the book provide examples for original, effective and necessary changes for envisioning educating science teachers for sustainability that will inform policy makers.

This book highlights cutting-edge research relevant to the building of a computational model of reading comprehension, as in the processing and understanding of a natural language text or story. The book takes an interdisciplinary approach to the study of reading, with contributions from computer science, psychology, and philosophy. Contributors cover the theoretical and psychological foundations of the research in discussions of what it means to understand a text, how one builds a computational model, and related issues in knowledge representation and reasoning. The book also addresses some of the broader issues that a natural language system must deal with, such as reading in context, linguistic novelty, and information extraction.
