In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of "Star Trek, "where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species--or the closed, dystopian, and ultimately self-destructive world of "Soylent Green." If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars. In this four-part e-special, Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin's relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier to humanity--the human race's future as a species that takes the necessary baby steps away from the cradle that is planet Earth or, ultimately, perishes here.

    Energy experts are all saying the same thing: solar photovoltaics (PV) is our future. Reports from universities, investment banks, international institutions and large investors agree. It's not about whether the switch from fossil fuels to solar power will happen, but when.Solar panels are being made that will last longer than ever hoped; investors are seeing the benefits of the long-term rewards provided by investing in solar; in the Middle East, a contractor can now offer solar-powered electricity far cheaper than that of a coal-fired power station. The Switch tracks the transition away from coal, oil and gas to a world in which the limitless energy of the sun provides much of the energy the 10 billion people of this planet will need. It examines both the solar future and how we will get there, and the ways in which we will provide stored power when the sun isn't shining. We learn about artificial photosynthesis from a start-up in the US that is making petrol from just CO2 and sunlight; ideas on energy storage are drawn from a company in Germany that makes batteries for homes; in the UK, a small company in Swindon has the story of wind turbines; and in Switzerland, a developer shows how we can use hydrogen to make 'renewable' natural gas for heating.Told through the stories of entrepreneurs, inventors and scientists from around the world, and using the latest research and studies, The Switch provides a positive solution to the climate change crisis, and looks to a brighter future ahead.

    His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft.Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an idealist inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.

    During the year as they cross-country ski, hike, bicycle, canoe, and backpack into Yellowstone's grandeur, Rick digs into important controversies: the outrage over the proposed removal of grizzlies from the endangered species list; the dispute over hunting park wolves along Yellowstone's border; the debate about whether wolves help or harm the ecosystem and the economy; the fight to stop the slaughter of park bison; the overuse of the park; and their community's battle to prevent gold mining on the park's border. Rick ends the year with a stronger love for Yellowstone's grandeur, a deeper knowledge of the controversies threatening the park, and a desire to inspire readers to protect our nation's first national park.

    Their wager on the future prices of five metals captured the public’s imagination as a test of coming prosperity or doom. Ehrlich, author of the landmark book The Population Bomb, predicted that rising populations would cause overconsumption, resource scarcity, and famine—with apocalyptic consequences for humanity. Simon optimistically countered that human welfare would flourish thanks to flexible markets, technological change, and our collective ingenuity. Simon and Ehrlich’s debate reflected a deepening national conflict over the future of the planet. The Bet weaves the two men’s lives and ideas together with the era’s partisan political clashes over the environment and the role of government. In a lively narrative leading from the dawning environmentalism of the 1960s through the pivotal presidential contest between Jimmy Carter and Ronald Reagan and on into the 1990s, Paul Sabin shows how the fight between Ehrlich and Simon—between environmental fears and free-market confidence—helped create the gulf separating environmentalists and their critics today. Drawing insights from both sides, Sabin argues for using social values, rather than economic or biological absolutes, to guide society’s crucial choices relating to climate change, the planet’s health, and our own.

    

    In this far-reaching narrative, Weisman explains how our massive infrastructure would collapse and finally vanish without human presence; which everyday items may become immortalized as fossils; how copper pipes and wiring would be crushed into mere seams of reddish rock; why some of our earliest buildings might be the last architecture left; and how plastic, bronze sculpture, radio waves, and some man-made molecules may be our most lasting gifts to the universe.The World Without Us reveals how, just days after humans disappear, floods in New York's subways would start eroding the city's foundations, and how, as the world's cities crumble, asphalt jungles would give way to real ones. It describes the distinct ways that organic and chemically treated farms would revert to wild, how billions more birds would flourish, and how cockroaches in unheated cities would perish without us. Drawing on the expertise of engineers, atmospheric scientists, art conservators, zoologists, oil refiners, marine biologists, astrophysicists, religious leaders from rabbis to the Dalai Lama, and paleontologists—who describe a prehuman world inhabited by megafauna like giant sloths that stood taller than mammoths—Weisman illustrates what the planet might be like today, if not for us.From places already devoid of humans (a last fragment of primeval European forest; the Korean DMZ; Chernobyl), Weisman reveals Earth's tremendous capacity for self-healing. As he shows which human devastations are indelible, and which examples of our highest art and culture would endure longest, Weisman's narrative ultimately drives toward a radical but persuasive solution that needn't depend on our demise. It is narrative nonfiction at its finest, and in posing an irresistible concept with both gravity and a highly readable touch, it looks deeply at our effects on the planet in a way that no other book has.

    It has built on itself for centuries, becoming vast and increasingly specialized. Most of us are ignorant about the fundamental principles of the civilization that supports us, happily utilizing the latest—or even the most basic—technology without having the slightest idea of why it works or how it came to be. If you had to go back to absolute basics, like some sort of postcataclysmic Robinson Crusoe, would you know how to re-create an internal combustion engine, put together a microscope, get metals out of rock, accurately tell time, weave fibers into clothing, or even how to produce food for yourself? Regarded as one of the brightest young scientists of his generation, Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. Every piece of technology rests on an enormous support network of other technologies, all interlinked and mutually dependent. You can’t hope to build a radio, for example, without understanding how to acquire the raw materials it requires, as well as generate the electricity needed to run it. But Dartnell doesn’t just provide specific information for starting over; he also reveals the greatest invention of them all—the phenomenal knowledge-generating machine that is the scientific method itself. This would allow survivors to learn technological advances not explicitly explored in The Knowledge as well as things we have yet to discover. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world as well as a thought experiment about the very idea of scientific knowledge itself.

    Armed with maps and cheerful curiosity, he travels from the oil-drunk boomtown of Fort McMurray, Alberta (a.k.a. Fort McMoney), down to the empty North Dakota plains, where mountains of pipe lie in wait for the torrent of crude that could soon start to flow if, as expected, the White House approves the controversial plan to turn on the spigots that will deliver oil from Canada directly to the Gulf of Mexico. Along the way, Horwitz meets a cavalcade of characters, including ranchers who either love or loathe the idea of oil flowing beneath their land, “rig pigs” and “cement heads” who are eager to make a buck in the tar fields, and strippers and other local entrepreneurs who are ready to help them spend it. He drives miles of lonesome road in his quest to understand what this pipeline means to everyone involved—from Native Americans to environmentalists to industry bureaucrats. He sees firsthand not only how an oil spill can devastate acres of rich farmland but how a town can be saved by an influx of new jobs. Over homemade farm dinners and countless tavern beers, Horwitz realizes that there are no easy answers, no right or wrong, no heroes or villains. The questions surrounding America’s energy future go beyond pat declarations about independence from foreign oil or destruction of Mother Earth. They go, some believe, to the very meaning of freedom.
