Alternative energy sources are becoming increasingly important in a world striving for energy independence, clean air, and a reprieve from global warming. Solar cells, wind power, and biofuels are some of the competing alternative energy sources hoping to gain a foothold in our future energy mix, and the economic advantages of these technologies are continually increasing as costs are reduced and efficiencies increased. Alternative Energy Technologies: An Introduction with Computer Simulations explores the science and engineering behind a number of emerging alternative energy technologies, including polymer solar cells, algae biofuels, and artificial leaves. It also addresses the environmental need for these technologies. However, unlike its predecessors, this book employs simple computer models implemented within spreadsheet environments to simulate different aspects of the alternative energy technologies and therefore teach the subject matter. This unique approach: Provides a dual introduction to alternative energy technologies and computer simulation Elucidates the fundamental behaviors and complex interactions within the alternative energy systems Makes computer simulation straightforward and accessible to readers with no prior programming experience Featuring investigative exercises that deepen understanding and inspire further research, Alternative Energy Technologies: An Introduction with Computer Simulations makes an ideal introductory textbook for undergraduate students and a valuable professional reference for experimental researchers.

The Third Industrial Revolution

How Lateral Power Is Transforming Energy, the Economy, and the World

Author: Jeremy Rifkin

The Industrial Revolution, powered by oil and other fossil fuels, is spiraling into a dangerous endgame. The price of gas and food are climbing, unemployment remains high, the housing market has tanked, consumer and government debt is soaring, and the recovery is slowing. Facing the prospect of a second collapse of the global economy, humanity is desperate for a sustainable economic game plan to take us into the future. Here, Jeremy Rifkin explores how Internet technology and renewable energy are merging to create a powerful "Third Industrial Revolution." He asks us to imagine hundreds of millions of people producing their own green energy in their homes, offices, and factories, and sharing it with each other in an "energy internet," just like we now create and share information online. Rifkin describes how the five-pillars of the Third Industrial Revolution will create thousands of businesses, millions of jobs, and usher in a fundamental reordering of human relationships, from hierarchical to lateral power, that will impact the way we conduct commerce, govern society, educate our children, and engage in civic life. Rifkin's vision is already gaining traction in the international community. The European Union Parliament has issued a formal declaration calling for its implementation, and other nations in Asia, Africa, and the Americas, are quickly preparing their own initiatives for transitioning into the new economic paradigm. The Third Industrial Revolution is an insider's account of the next great economic era, including a look into the personalities and players — heads of state, global CEOs, social entrepreneurs, and NGOs — who are pioneering its implementation around the world.

Natural and Artificial Photosynthesis

Solar Power as an Energy Source

This technical book explores current and future applications of solar power as an unlimited source of energy that earth receives every day. Photosynthetic organisms have learned to utilize this abundant source of energy by converting it into high-energy biochemical compounds. Inspired by the efficient conversion of solar energy into an electron flow, attempts have been made to construct artificial photosynthetic systems capable of establishing a charge separation state for generating electricity or driving chemical reactions. Another important aspect of photosynthesis is the CO2 fixation and the production of high energy compounds. Photosynthesis can produce biomass using solar energy while reducing the CO2 level in air. Biomass can be converted into biofuels such as biodiesel and bioethanol. Under certain conditions, photosynthetic organisms can also produce hydrogen gas which is one of the cleanest sources of energy.

Out of print since 2006, this book is now available online. Click here! A base on the Moon, an expedition to Mars. . . . Some time in the near future, for scientific or cultural reasons, humanity will likely decide to pursue one of these fantastic ventures in space. How can we increase the scope and reduce the cost of these ambitious activities?The parts of the solar system that are most accessible from Earth--the Moon, the near-Earth asteroids, Mars and its moons--are rich in materials of great potential value to humanity. Resources of Near-Earth Space explores the possibilities both of utilizing these materials to produce propellants, structural metals, refractories, life-support fluids, and other materials on site to reduce the costs of space exploration, and of providing a source of materials and energy for our own planet that would not be environmentally destructive to Earth.This volume summarizes the present state of the art in attempts to realize these possibilities: identifying the resources, mining and processing, transportation, and economics. As a broad survey of a rapidly evolving field, it is intended as a technical introduction to the use of nonterrestrial materials for scientists, engineers, and industrial and governmental project managers who seek to make space more accessible.

Energy Efficiency Research

Energy efficiency is increased when an energy conversion device, such as a steam turbine, undergoes a technical change that enables it to produce more heat or electricity from the same amount of fuel. This contrasts with energy conservation and energy curtailment. The cumulative effect of energy efficiency can be enormous and significant in a country like the United States which uses so much more energy than it produces. This book brings together important research and analyses which put this critical issue in perspective.

Every student who wants to succeed in the global economy should study abroad. It is one of the most valuable things you can do for yourself and your career. Each of us has lived and worked both in the United States and overseas, working extensively with both students and employers in a variety of business, academic and not-for-profit settings in our own careers. Stacie Nevadomski Berdan is a seasoned global executive, an expert on international careers, and an award-winning author on how to succeed in the global marketplace. Sir Cyril Taylor has been an innovator in study abroad for nearly 50 years, having founded the American Institute For Foreign Study (AIFS) in 1964, and Richmond, The American International University in London in 1972. As the president and CEO of the Institute of International Education, Allan Goodman is a leader in creating and expanding international educational exchange opportunities, and making them more accessible to more diverse student populations. He was previously a professor and the executive dean of the School of Foreign Service at Georgetown University, teaching students who are now in diplomatic leadership positions around the globe. Together, we and our organizations have advised and supported hundreds of thousands of students over the years to gain an international experience, and we continue to advocate for more students going abroad. We have seen firsthand the value of making international a part of one’s education and of listening to others when it comes to adapting to life in another country. We have all felt culture shock and also re-entry problems, and we have seen the impact of an international experience on those who have been fortunate enough to have one. But we realize that not every student knows where to start and how to make it happen. So we teamed up to reach students like you, who are still exploring whether and how to study abroad, and wondering if they should do it. The answer is a resounding “yes”—but only after you have prepared yourself to take full advantage of the opportunity. We wrote this book to give every student access to the best information available on study abroad—things to know before you go, how to make the most of your time abroad, why you should consider internships and career-related experiences abroad, how to transition back to life in the States, and, as you embark on your career, how to use study abroad to showcase your global growth and learning. To bring you current, relevant advice, we surveyed approximately 350 students and asked dozens of educators and business leaders to share their insights. In addition to our own best advice from years of working in international education and communications, we aim to offer you timely and practical feedback from the current generation of students who have made the most of their time abroad. Therefore, we have included more than 200 real-life stories from a diverse collection of students, advisers and professionals, as well as 100 easy-to-follow tips to help guide you through the process. The wide range of programs currently available makes study abroad more flexible, affordable and accessible than ever before. While not everyone can go abroad for a full year in a total language immersion setting, we hope you will agree after reading this book that there is a study abroad option for everyone. We urge you to make international a part of your education.

Can We Talk about Race?

And Other Conversations in an Era of School Resegregation

Major new reflections on race and schools—by the best-selling author of “Why Are All the Black Kids Sitting Together in the Cafeteria?“ A Simmons College/Beacon Press Race, Education, and Democracy Series Book Beverly Daniel Tatum emerged on the national scene in 1997 with “Why Are All the Black Kids Sitting Together in the Cafeteria?,“ a book that spoke to a wide audience about the psychological dynamics of race relations in America. Tatum’s unique ability to get people talking about race captured the attention of many, from Oprah Winfrey to President Clinton, who invited her to join him in his nationally televised dialogues on race. In her first book since that pathbreaking success, Tatum starts with a warning call about the increasing but underreported resegregation of America. A selfdescribed “integration baby“—she was born in 1954—Tatum sees our growing isolation from each other as deeply problematic, and she believes that schools can be key institutions for forging connections across the racial divide. In this ambitious, accessible book, Tatum examines some of the most resonant issues in American education and race relations: • The need of African American students to see themselves reflected in curricula and institutions • How unexamined racial attitudes can negatively affect minority-student achievement • The possibilities—and complications—of intimate crossracial friendships Tatum approaches all these topics with the blend of analysis and storytelling that make her one of our most persuasive and engaging commentators on race. Can We Talk About Race? launches a collaborative lecture and book series between Beacon Press and Simmons College, which aims to reinvigorate a crucial national public conversation on race, education and democracy.

A NEW YORK TIMES BESTSELLER An unlikely political star tells the inspiring story of the two-decade journey that taught her how Washington really works—and really doesn't—in A Fighting Chance As a child in small-town Oklahoma, Elizabeth Warren yearned to go to college and then become an elementary school teacher—an ambitious goal, given her family's modest means. Early marriage and motherhood seemed to put even that dream out of reach, but fifteen years later she was a distinguished law professor with a deep understanding of why people go bankrupt. Then came the phone call that changed her life: could she come to Washington DC to help advise Congress on rewriting the bankruptcy laws? Thus began an impolite education into the bare-knuckled, often dysfunctional ways of Washington. She fought for better bankruptcy laws for ten years and lost. She tried to hold the federal government accountable during the financial crisis but became a target of the big banks. She came up with the idea for a new agency designed to protect consumers from predatory bankers and was denied the opportunity to run it. Finally, at age 62, she decided to run for elective office and won the most competitive—and watched—Senate race in the country. In this passionate, funny, rabble-rousing book, Warren shows why she has chosen to fight tooth and nail for the middle class—and why she has become a hero to all those who believe that America's government can and must do better for working families.

An inspirational memoir tracing Lester Brown’s life from a small-farm childhood to leadership as a global environmental activist. Lester R. Brown, whom the Washington Post praised as “one of the world’s most influential thinkers,” built his understanding of global environmental issues from the ground up. Brown spent his childhood working on the family’s small farm. His entrepreneurial skills surfaced early. Even while excelling in school, he launched with his younger brother a tomato-growing operation that by 1958 was producing 1.5 million pounds of tomatoes. Later, at the U.S. Department of Agriculture, Brown emphasized the need for systemic thinking. In 1963 he did the first global food supply and demand projections to the end of the century. While on a brief assignment in India in 1965, he pieced together the clues that led him to sound the alarm on an impending famine there. His urgent warning to the U.S. and Indian governments set in motion the largest food rescue effort in history, helping to save millions of lives. This experience led India to adopt new agricultural practices, which he helped to shape. Brown went on to advise governments internationally and to found the Worldwatch and Earth Policy institutes, two major nonprofit environmental research organizations. Both brilliant and articulate, through his many books he has brought to the fore the interconnections among such issues as overpopulation, climate change, and water shortages and their effect on food security. His 1995 book, Who Will Feed China?, led to a broad restructuring of China’s agricultural policy. Never one to focus only on the problem, Brown always proposes pragmatic, employable solutions to stave off the unfolding ecological crises that endanger our future.
