People have harnessed the formidable power of moving water for millennia, but they have only used it to generate electricity since the late nineteenth century. Since that time, it has become an important alternative energy source to fossil fuels. In fact, more electricity is produced by waterpower than by any other renewable energy source in the United States. This book offers an in-depth look at the turbines used to generate hydroelectricity. It explains which locations are best for generating hydroelectricity and explores the cultural and environmental concerns raised by the building of dams. The focus is on hydroelectric plants, but this book also discusses pumped hydro storage, tidal power, and wave energy.

From tissue engineering that produces artificial skin for burn patients to the use of nanotechnology for precise drug delivery, recent advances in bioengineering have fundamentally changed both the world in which we live and the bodies within which we live. Among the topics covered in this invaluable compendium are homeostasis, biological and artificial control systems, diagnostic imaging, prostheses, biomaterials, environmental engineering, and various subfields of bioengineering. Readers will become familiar with the most exciting and significant developments in this important field.

Farms of massive wind turbines, often framed by majestic mountains or with their bases lapped by ocean waves, have become one of the most recognizable images of alternative energy. This book covers the history of wind power, today's advanced turbines and wind farms, and the advantages and disadvantages of this fast-growing energy technology. It even presents a substantive but easy-to-understand explanation of how and where winds form. It's a great resource for the study of science and technology, as well as those curious about the possible solutions to the problems arising from the global consumption of fossil fuels.

HOW MUCH IS A LIFE WORTH? WHEN THE WORLD DEMANDS AN ANSWER WE ALL SCRAMBLE TO FIND ONE.My name is Midnight Thunder. The town crazy person; the Demon Eyes girl. The girl whose existence rests on a curse that saves her from death yet sets her on a path to an inevitable end.I live in a world full of magic: spells, curses, enchantments, and everything in between. It would be a whimsical place, but, like anything, it's imperfect. Little by little, my own country has begun to fall apart beneath its own mistakes. The queen’s gone a little bit more than mad, our military has collapsed, and of course, the only way to break the deadly curse at the root of it all is to sacrifice... me.

Many people associate geothermal energy with watching dramatic geyser eruptions or relaxing in a steaming natural hot spring. However, heat from within the Earth can also be used to generate electricity and heat buildings. Readers learn about the past, present, and future of geothermal power through this informative book. Topics covered include how geothermal heat is created and brought up to Earth's surface, the surface features, such as lava flows, hot springs, geysers, and fumaroles, that are signs of it, and how geothermal heat pumps and geothermal power plants work. The need for renewable energy sources such as geothermal energy is addressed, as is the need to manage geothermal resources sustainably.

Coal, oil, and natural gas supply the vast majority of the energy that we use in modern life, whether that means generating electricity for lights and computers or fuelling the engines that power our cars, buses, and airplanes. Readers will learn how these ancient fuels formed, as well as how human beings extract them from the ground for our use. They'll also learn about the downsides of fossil fuels, such as their limited supply and the environmental damage that burning them produces. Photographs from around the world and maps and diagrams from Encyclopedia Britannica add a compelling visual learning element.

We owe our understanding of the world around us to the insights and experiments of countless scientists. This volume introduces just over one hundred of the most influential figures in the history of the field. It spans thousands of years, from Thales of Miletus (who flourished in the sixth century BCE) to living luminaries, such as Craig Mello, Neil deGrasse Tyson, and Shinya Yamanaka. The varied and fascinating list includes physicists, chemists, anthropologists, astronomers, geologists, biologists, and more, all of whom have added to our store of scientific knowledge.

Although the sun beams out more than enough energy to meet the needs of all of Earth's population, at the moment only a small percentage of the power we use is generated through the use of solar energy technologies. This volume examines the factors that have limited the role of solar power in the past and discusses some of the developments that promise to make it more significant in the future. Readers will learn about various methods for collecting solar power, such as concentrating collectors, flat-plate collectors, and photovoltaic cells. The opening chapter focuses on the sun itself, explaining the thermonuclear reactions that produce energy there.
