Imagine your family had to choose between sending you to school or having enough food to eat. This book tells how William Kamkwamba was forced to drop out of his school in Wimbe, Malawi, when a famine struck his village and his family, who relied on farming, could no longer afford his tuition fee. Instead of giving up on his education, William visited his local library often. It was here that he read a book about wind power. At the age of 14, William used what he learned from the book to build a windmill that brought power to his family's home. He has since built his village's first drinking water pump. William's ingenuity, perseverance, and initiative are an inspiration to many people around the world. Teacher's guide available.
Now a Netflix Film, Starring and Directed by Chiwetel Ejiofor of 12 Years a Slave 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.
Now a Netflix film starring and directed by Chiwetel Ejiofor, this is a gripping memoir of survival and perseverance about the heroic young inventor who brought electricity to his Malawian village. When a terrible drought struck William Kamkwamba's tiny village in Malawi, his family lost all of the season's crops, leaving them with nothing to eat and nothing to sell. William began to explore science books in his village library, looking for a solution. There, he came up with the idea that would change his family's life forever: he could build a windmill. Made out of scrap metal and old bicycle parts, William's windmill brought electricity to his home and helped his family pump the water they needed to farm the land. Retold for a younger audience, this exciting memoir shows how, even in a desperate situation, one boy's brilliant idea can light up the world. Complete with photographs, illustrations, and an epilogue that will bring readers up to date on William's story, this is the perfect edition to read and share with the whole family.
This revised edition is fully updated and continues to provide the best in-depth introduction to renewable energy science.

The authors avoid technical jargon and advanced math, but address fundamental analytical skills with wide application, including: Two brand new chapters giving an introduction to population dynamics and statistical analysis for energy studies Additional self-study problems and answers More worked examples Up-to-date coverage of areas such as hydraulic fracturing, integration of renewable energy to power grid, and cost.
This book is a sequel to Rural development : putting the last first (AL. 1719, BRN 32006). It explores methods and approaches of participatory rural appraisal (PRA), which, because of its wide application, should, according to the author, be changed to participatory learning and action (PLA).

In All Things Must Fight to Live, Bryan Mealer takes readers on a harrowing two-thousand mile journey through Congo, where gun-toting militia still rape and kill with impunity. Amidst burnt-out battlefields where armies still wrestle for control, into the dark corners of the forests, and along the high savanna, where thousands have been slaughtered and quickly forgotten, Mealer searches for signs that Africa's most troubled state will soon rise from ruin. At once illuminating and startling, All Things Must Fight to Live is a searing portrait of an emerging country facing unimaginable upheaval and almost impossible odds, as well as an unflinching look at the darkness that continues to exist in the hearts of men. It is non-fiction at its finest-powerful, moving, necessary.
