Let It Shine: The 6,000-Year Story of Solar Energy
by John PerlinThe definitive history of solar power and technology Even as concern over climate change and energy security fuel a boom in solar technology, many still think of solar as a twentieth-century wonder. Few realize that the first photovoltaic array appeared on a New York City rooftop in 1884, or that brilliant engineers in France were using solar power in the 1860s to run steam engines, or that in 1901 an ostrich farmer in Southern California used a single solar engine to irrigate three hundred acres of citrus trees. Fewer still know that Leonardo da Vinci planned to make his fortune by building half-mile-long mirrors to heat water, or that the Bronze Age Chinese used hand-size solar-concentrating mirrors to light fires the way we use matches and lighters today. With thirteen new chapters, Let It Shine is a fully revised and expanded edition of A Golden Thread, Perlin’s classic history of solar technology, detailing the past forty years of technological developments driving today’s solar renaissance. This unique and compelling compendium of humankind’s solar ideas tells the fascinating story of how our predecessors throughout time, again and again, have applied the sun to better their lives — and how we can too.
Let It Snow: Keeping Canada's Winter Sports Alive
by Darryl Humber William HumberWinter has shaped Canada’s image and has been embraced with hearty enthusiasm from snowshoeing hikers in the nineteenth century, to future hockey stars on backyard rinks, to the indoor spectacle of figure-skating carnivals and curling bonspiels. Much of our literature, our songs, and our memories of youth reflect the bracing tonic that winter brings even as we curse the ice-laden roads on morning commutes or during weekend ski trips. But alas, winter’s demise to a weak reminder of its former glory is a real possibility as climate change wreaks long-term havoc. This timely book takes a fond look at winter’s past, its place in Canada’s story, and how it has shaped our sports history. It also explores what climate change means for our sense of Canadian identity, for our winter sports heritage and its related industries, and for our ability to hold winter sporting events beyond the 2010 Winter Olympics in Vancouver.
Let me Speak!: Testimony of Domitila, a Woman of the Bolivian Mines
by Moema Viezzer Domitila Barrios de ChungaraFirst published in English in 1978, this classic book contains the testimony of Domitila Barrios de Chungara, the wife of a Bolivian tin miner. Blending firsthand accounts with astute political analysis, Domitila describes the hardships endured by Bolivia's vast working class and her own efforts at organizing women in the mining community. The result is a gripping narrative of class struggle and repression, an important social document that illuminates the reality of capitalist exploitation in 1970s Bolivia. Domitila Barrios de Chungara was born in 1937 in the Siglo XX mining town in Bolivia. She became politically active in the 1960s and, in 1975, participated in the UN International Women's Year Tribunal in Mexico. In 2005 she was nominated alongside 999 other "Peace Women" for a collective Nobel Peace Prize.

Let Them Eat Shrimp: The Tragic Disappearance of the Rainforests of the Sea
by Kennedy WarneWhat's the connection between a platter of jumbo shrimp at your local restaurant and murdered fishermen in Honduras, impoverished women in Ecuador, and disastrous hurricanes along America's Gulf coast? Mangroves. Many people have never heard of these salt-water forests, but for those who depend on their riches, mangroves are indispensable. They are natural storm barriers, home to innumerable exotic creatures--from crabeating vipers to man-eating tigers--and provide food and livelihoods to millions of coastal dwellers. Now they are being destroyed to make way for shrimp farming and other coastal development. For those who stand in the way of these industries, the consequences can be deadly. In Let Them Eat Shrimp, Kennedy Warne takes readers into the muddy battle zone that is the mangrove forest. A tangle of snaking roots and twisted trunks, mangroves are often dismissed as foul wastelands. In fact, they are supermarkets of the sea, providing shellfish, crabs, honey, timber, and charcoal to coastal communities from Florida to South America to New Zealand. Generations have built their lives around mangroves and consider these swamps sacred. To shrimp farmers and land developers, mangroves simply represent a good investment. The tidal land on which they stand often has no title, so with a nod and wink from a compliant official, it can be turned from a public resource to a private possession. The forests are bulldozed, their traditional users dispossessed. The true price of shrimp farming and other coastal development has gone largely unheralded in the U.S. media. A longtime journalist, Warne now captures the insatiability of these industries and the magic of the mangroves. His vivid account will make every reader pause before ordering the shrimp.

The Letters and Journals of Simon Fraser, 1806-1808
by W. Kaye Lamb Michael GnarowskiB.C. journalist Stephen Hume has said that fur trader and explorer Simon Fraser should be celebrated as the founder of British Columbia. Certainly, the achievements of the Scottish-descended United Empire Loyalist adventurer were impressive. During three extraordinary years, 1805-1808, Fraser undertook the third major expedition (after Alexander Mackenzie’s and Lewis and Clark’s) across North America, culminating in his famous journey down the river in British Columbia that now bears his name. Employed by the Montreal-based North West Company, Fraser was responsible for building many of British Columbia’s first trading posts. His exploratory efforts helped lead to Canada’s boundary later being declared at the 49th parallel. In this new volume, librarian and archivist W. Kaye Lamb provides a detailed introduction as well as illuminating annotations to Fraser’s journals, which were originally published by Macmillan of Canada in 1960.
Letters From Katrina: Stories Of Hope And Inspiration
by Mark Hoog Kim LemaireThis project began in the spring of 2005 when students in one elementary classroom in Colorado were asked to participate in a unique book drive for the children along the gulf coast. Each Colorado student was given a new Growing Field children's picture book and, inside of it, invited to write a letter to a student along the gulf coast affected by Hurricane Katrina. The result, which includes schools, classrooms and students from California to Virginia, has been magical. In searching their heart and mind for meaningful words to write. . . the children found their own voice of value and a way to make their own special contribution. Through their words of hope, inspiration and friendship they have reached out to inspire their friends throughout Mississippi to believe that life is still without limit. The letters written by our next greatest generation are profiled in this new book and will soon be available for you to purchase. This elegant coffee table book illustrates the difference each of us makes when reaching out to others in need. The letters written by elementary students serve as a powerful reminder that the world can be changed when we ask not about gender, race, religion or socio-economic status but instead share with others six magical words that will truly change the world. . . I hope we can be friends. 100% of the proceeds from the sale of this book will be placed in an endowment that will create a lifetime of scholarships and opportunity for children throughout Mississippi and the Gulf Coast.
Levees and Dams: Advances in Geophysical Monitoring and Characterization
by Juan Lorenzo William DollThis book aims to inform policy-makers, engineers and earth scientists about the current and emerging role of geophysics in addressing environmental processes, assessments, and policy directions related to new and existing dams and levees. Until now geophysics has concentrated on characterization and remediation of dams and levees, but now the field is changing our understanding on the influence of natural processes (e.g., floods, dissolution) and human activities in the design, and management of these structures.This monograph includes advances in the following fields of Dams and Levees studies: · New insights from small and mid-sized laboratory experiments· Integrated methods electromagnetic, seismic, potential methods· Inverse modeling approaches· Statistical considerations· Monitoring of processes attending aging structures · Hazard monitoring· Risk Analysis
Levees and the National Flood Insurance Program
by Committee on Levees the National Flood Insurance Program Improving Policies PracticesThe Federal Emergency Management Agency's (FEMA) Federal Insurance and Mitigation Administration (FIMA) manages the National Flood Insurance Program (NFIP), which is a cornerstone in the U. S. strategy to assist communities to prepare for, mitigate against, and recover from flood disasters. The NFIP was established by Congress with passage of the National Flood Insurance Act in 1968, to help reduce future flood damages through NFIP community floodplain regulation that would control development in flood hazard areas, provide insurance for a premium to property owners, and reduce federal expenditures for disaster assistance. The flood insurance is available only to owners of insurable property located in communities that participate in the NFIP. Currently, the program has 5,555,915 million policies in 21,881 communities3 across the United States. The NFIP defines the one percent annual chance flood (100-year or base flood) floodplain as a Special Flood Hazard Area (SFHA). The SFHA is delineated on FEMA's Flood Insurance Rate Maps (FIRM's) using topographic, meteorologic, hydrologic, and hydraulic information. Property owners with a federally back mortgage within the SFHAs are required to purchase and retain flood insurance, called the mandatory flood insurance purchase requirement (MPR). Levees and floodwalls, hereafter referred to as levees, have been part of flood management in the United States since the late 1700's because they are relatively easy to build and a reasonable infrastructure investment. A levee is a man-made structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to provide protection from temporary flooding. A levee system is a flood protection system which consists of a levee, or levees, and associated structures, such as closure and drainage devices, which are constructed and operated in accordance with sound engineering practices. Recognizing the need for improving the NFIP's treatment of levees, FEMA officials approached the National Research Council's (NRC) Water Science and Technology Board (WSTB) and requested this study. The NRC responded by forming the ad hoc Committee on Levee and the National Flood Insurance Program: Improving Policies and Practices, charged to examine current FEMA treatment of levees within the NFIP and provide advice on how those levee-elated policies and activities could be improved. The study addressed four broad areas, risk analysis, flood insurance, risk reduction, and risk communication, regarding how levees are considered in the NFIP. Specific issues within these areas include current risk analysis and mapping procedures behind accredited and non-accredited levees, flood insurance pricing and the mandatory flood insurance purchase requirement, mitigation options to reduce risk for communities with levees, flood risk communication efforts, and the concept of shared responsibility. The principal conclusions and recommendations are highlighted in this report.
