Austrian naturalist Viktor Schauberger (1885-1958) was far ahead of his time. From his unusually detailed observations of the natural world, he pioneered a completely new understanding of how nature works. He also foresaw, and tried to warn against, the global waste and ecological destruction of our age. This book describes and explains Schauberger's insights in contemporary, accessible language. His remarkable discoveries -- which address issues such as sick water, ailing forests, climate change and, above all, renewable energy -- have dramatic implications for how we should work with nature and its resources.

New York Times Bestseller ”Enestående, tryllebindende og virkelig skræmmende … hver eneste skridt er ladet medspænding … fantastisk.” The New York Times Historien om Tjernobyl er langt mere kompleks, mere menneskelig og mere skræmmende end myten om det sovjetiske rige. I denne afgørende og afslørende bog, der bygger på interviews, breve, uudgivne memoirer og dokumenter fra nyligt åbne arkiver, bringer Adam Higginbotham katastrofen i 1986 til live gennem øjnene af de mænd og kvinder, der var vidner til ulykken. Det er en historie, der i mange år har været omdiskuteret, og som fra start til slut har været indhyllet i hemmeligheder, propaganda og vildledende informationer. Med”Tjernobyl. Den ufortalte historie” præsenterer Adam Higginbotham et uforglemmeligt og dybdegående portræt af verdens værste atomkatastrofe, som samtidig er skræmmende relevant i vores dages diskussioner om klimaforandringer og energikrise.

AFSLUTTENDE DEL AF MIRRIN BANK-TRILOGIENIran har angrebet NATO og USAs præsident Cahill gør klar til at anvende atomvåben mod Iran.Samtidig ser Rusland sit snit til at udvide sit territorium.Under dække af at være en investeringsbank opdager vores hemmelige efterretningstjeneste i København, Mirrin Bank, at Iran i det skjulte har produceret 200 højteknologiske atomsprænghoveder og er således en de facto atommagt. Angriber præsident Cahill Iran risikerer verden en altødelæggende atomvinter. Vores Team i Mirrin Bank finder yderligere ud af, at en langt værre spiller, The Church, står bag og trækker i trådene, for at udleve en altødelæggende religiøs vision. The Church har millioner af medlemmer over hele verden, og noget tyder på, at de har infiltreret flere vestlige demokratier … ⭐️⭐️⭐️⭐️ "Actionfilm i bogformat."

A groundbreaking history of architecture told through the relationship between buildings and energyThe story of architecture is the story of humanity. The buildings we live in, from the humblest pre-historic huts to today's skyscrapers, reveal our priorities and ambitions, our family structures and power structures. And to an extent never explored until now, architecture has been shaped in every era by our access to energy, from fire to farming to fossil fuels.In this ground-breaking history of world architecture, Barnabas Calder takes us on a dazzling tour of some of the most astonishing buildings of the past fifteen thousand years, from Uruk, via Ancient Rome and Victorian Liverpool, to China's booming megacities. He reveals how every building - from the Parthenon to the Great Mosque of Damascus to a typical Georgian house - was influenced by the energy available to its architects, and why this matters.Today architecture consumes so much energy that 40% of the world's greenhouse gas emissions come from the construction and running of buildings. If we are to avoid catastrophic climate change then now, more than ever, we need beautiful but also intelligent architecture, and to retrofit - not demolish - the buildings we already have.

The Faraday Press Edition of István Novák's historic Power Distribution Network Design Methodologies brings to print important coverage of power system design topics including circuit board layout strategies, capacitor characterization and selection, controlled impedance design and guidance for system-level engineering.Power Distribution Network (PDN) design procedures are covered in practical detail-covering topics including the buck converter topology, the proper selection and placement of bypass capacitors, power requirements of memory systems, powering FPGAs and designing/controlling wideband power delivery impedances. As clock speeds and power density requirements progress, the challenges of a robust system design becomes more and more important.Power Distribution Network Design is a valuable resource for the global community of power supply designers.

Tjernobyl-atomkraftværket er en stor og imponerende bygning, der hurtigt får træerne i skoven omkring det til at se små ud. For mange var dette enorme industrielle monster et symbol på Sovjetunionens ambitioner. Beliggende i Ukraine (en del af Sovjetunionen indtil 1989), cirka 16 km nordvest for byen Tjernobyl, begyndte arbejdet på kraftværket i 70’erne, hvor den første reaktor blev taget i brug i 1977. I 1984 var fire reaktorer aktive. Hver reaktor kunne producere en gigawatt elektricitet, og kraftværket leverede omkring 10 procent af Ukraines elektricitet. Men Sovjet stoppede ikke der. I 1986 byggede landet yderligere to reaktorer med ambitionen om at gøre Tjernobyl til et af verdens største atomkraftværker.Denne artikel fortæller historien om, hvordan et tilsyneladende rutine-sikkerhedstjek førte til den værste atomulykke i det 20. århundrede – og enden på Sovjetunionen.HISTORIE er en serie om historiske begivenheder og personer, der har fascineret og interesseret os i generationer. I korte artikler og reportager får vi indblik i historiens omtalte foreteelser og øjeblikke.Artiklen er oprindeligt udgivet af Orage.

A WALL STREET JOURNAL BESTSELLER "If you're in any kind of leadership role-whether at a company, a non-profit, or somewhere else-there's a lot you can learn here."-Bill Gates, Gates NotesHow could General Electric-perhaps America's most iconic corporation-suffer such a swift and sudden fall from grace? This is the definitive history of General Electric's epic decline, as told by the two Wall Street Journal reporters who covered its fall. Since its founding in 1892, GE has been more than just a corporation. For generations, it was job security, a solidly safe investment, and an elite business education for top managers. GE electrified America, powering everything from lightbulbs to turbines, and became fully integrated into the American societal mindset as few companies ever had. And after two decades of leadership under legendary CEO Jack Welch, GE entered the twenty-first century as America's most valuable corporation. Yet, fewer than two decades later, the GE of old was gone. ​Lights Out examines how Welch's handpicked successor, Jeff Immelt, tried to fix flaws in Welch's profit machine, while stumbling headlong into mistakes of his own. In the end, GE's traditional win-at-all-costs driven culture seemed to lose its direction, which ultimately caused the company's decline on both a personal and organizational scale. Lights Out details how one of America's all-time great companies has been reduced to a cautionary tale for our times.
