Paperback. Etat : Very Good. London, 1923. Newly minted research assistant Saffron Everleigh is the first woman to hold the position at University College of London. When she attends a dinner party for the school, she expects to engage in conversations about the university's large expedition to the Amazon. What she doesn't expect is for Mrs. Henry, one of the professors' wives, to drop to the floor, poisoned by an unknown toxin. Dr. Maxwell, Saffron's mentor, is the main suspect, and evidence quickly mounts. Joined by flirtatious fellow researcher Alexander Ashton, Saffron uses her knowledge of botany as she explores steamy greenhouses, dark gardens, and deadly poisons to clear Maxwell's name. Will she be able to uncover the truth, or will her investigation land her on the murderer's list? In this entertaining examination of society's expectations, debut author Kate Khavari deftly sheds a light on the struggles of women in a male-dominated field, wrapped in mystery and murder.…

Paperback. Etat : Very Good. Electricity brings us back to an upbringing we may not have experienced but can certainly relate to.Taking a step back into her Hebridean childhood, Granny writes to her granddaughter in Australia, decorating her notebooks with hand-drawn scribbles and doodles. Though she may now live in Edinburgh, she relives her memories with a sense of warmth and protection.Yet, it is more than simple nostalgia for a time she cannot return to. At its core, Electricity is about community, and what it is to involve it in your life fully. Electricity itself sparked across the Hebrides and changed the lives of its people forever. You become more than your family, friends, or even neighbours. The landscape itself floods into your DNA. It is something that you will never separate from.This latest novel from award-winning writer Angus Peter Campbell has already garnered attention across the board. It will be not only popular with rural Scots but those who long for the simpler times they grew up in - times when we were more physically connected.…

Hardback. Etat : Very Good. In Electricity and Magnetism, children will unravel the secrets of science with simple experiments using easy-to-find ingredients. In this title in the Let's Experiment series, children are accompanied by two characters: Professor Albert, who will teach them the scientific explanation behind each experiment; and Greg the Robot, who will guide them in their practice. They'll have a ton of fun learning how magnetic force works, how to make and use a compass, build a circuit, and much more For each experiment, there is also a mess-o-meter for parents to know how messy the experiment can be, as well as the level of difficulty.…

Hardback. Etat : Good. 1.2 billion people on Earth still don't have electricity. Even where cell phones are now common, like sub-Saharan Africa and parts of India, villagers still walk miles to charge them. But new large-scale, sustainable solutions will not only usher in a new era of light, but be an important first step in lifting people from poverty and putting them on a road of sustainable economic development. Also, a unique, transforming opportunity for Western thinkers and practitioners will be created. These areas have largely skipped the analog stage of power development, and have moved straight from the middle ages to the digital age. They are not encumbered by existing infrastructure, dependence on fossil fuels, or too many outdated laws and regulations. An ideal innovation incubator, the developing world might just be the best way to make progress on our own energy issues at home. Jim Rogers is leading a grand collaborative effort to bring sustainable, clean electrical power to everyone who lacks it. This reverse engineering, he contends, could solve the energy crises of America and Europe, while also making the world a cleaner, smarter place. But it won't be easy. In Lighting the World, Rogers details the bold thinking, international cooperation, and political will required to illuminate the future for everyone.…

Hardback. Etat : Fair. Soon to be a Netflix film William Kamkwamba was born in Malawi, a country where magic ruled and modern science was mystery. It was also a land withered by drought and hunger. But William had read about windmills, and he dreamed of building one that would bring to his small village a set of luxuries that only 2 percent of Malawians could enjoy: electricity and running water. His neighbors called him misala--crazy--but William refused to let go of his dreams. With a small pile of once-forgotten science textbooks; some scrap metal, tractor parts, and bicycle halves; and an armory of curiosity and determination, he embarked on a daring plan to forge an unlikely contraption and small miracle that would change the lives around him. The Boy Who Harnessed the Wind is a remarkable true story about human inventiveness and its power to overcome crippling adversity. It will inspire anyone who doubts the power of one individual's ability to change his community and better the lives of those around him.…

Hardback. Etat : Very Good. If, in the ancient world, it was guns and germs and steel that determined the fates of people and nations, in modern times it is electricity. No other form of power translates into affluence and influence like it. Though demand for it is growing exponentially, it remains one of the most difficult forms of energy to supply and to do so reliably. Storage is even harder. This paradox has shaped global politics, affected the outcome of wars, and underlies the growing chasm between rich and poor, educated and uneducated. It is changing the game for business, and the requirements of national defence. It is altering the landscape and complicating the task of dealing effectively with climate change. In this book, Robert Bryce explains the unique nature of electricity as a commodity. He draws on stories from history to illustrate the stunning impact of our quest to harness it, illuminates exactly what is required to successfully sustain it, and explores the impact on societies and individuals when it collapses. As billions of people around the world still live in darkness, the gap between the electricity haves and have-nots widens, with profound political and ethical consequences. Modern life, even civilisation, has become ever more dependent on a source of energy that must be produced locally and in the moment, in a reliably steady stream at particular wattage, conveyed on wires strung on poles or threaded through pipes. If the lights go out, so does our manner of living, with potentially devastating consequences.…

Hardback. Etat : Very Good. Nikola Tesla was an eccentric genius who out-Edisoned Edison and out Marconied Marconi. Born of modest means in what is now Croatia and later becoming a naturalized American citizen, Tesla's inventions include the alternating current (AC) that powers our homes today, radio, wireless transmission, X-rays, and the electrifying Tesla coil. He even worked on development of direct energy weapons (death rays) and vertical takeoff and landing (VTOL) aircraft. During his lifetime Tesla moved first to Paris, then to New York, and after a period of time in Colorado Springs back to New York City where he maintained two laboratories. Along the way he worked for Edison, then became his biggest rival, and formed friendships with such divergent personalities as George Westinghouse, Mark Twain, a pigeon, all while reflecting on a childhood cat. His idiosyncrasies included an obsession with numbers divisible by three, ardent gambling, and a near-pathological fear of germs. He rarely slept more than a few hours at a time, often going days without rest. While generally soft-spoken, he could be a consummate showman, often insisting that his Tesla coil be present while he lectured, seemingly shooting lightning bolts as he spoke. In the end he died alone and nearly penniless, having ceded perhaps billions of dollars in royalties to his friend George Westinghouse. This illustrated book takes us through Tesla's life, his experiments and contributions to science, and brings us into his complex mind. Through ample use of his writings and interviews with the societies and inventors clubs that honor his name, we explore Tesla's methods and discoveries, personality quirks, and his legacy for the modern world - both scientific and popular culture. …
