“An engaging volume that will encourage both budding scientists and anyone intrigued by the creative process.” — Kirkus Reviews Here is the story of the ambitious young man who brought life-changing ideas to America, despite the obstructive efforts of his hero-turned-rival, Thomas Edison. From using alternating current to light up the Chicago World’s Fair to harnessing Niagara Falls to electrify New York City and beyond, Nikola Tesla was a revolutionary ahead of his time. Established biographer Elizabeth Rusch sheds light on this extraordinary figure, while fine artist Oliver Dominguez brings his life and inventions to vivid color. Back matter includes additional information about Tesla, scientific notes and explanations, source notes, a bibliography, and suggestions for further reading.
The history of the grid, the world's largest interconnected power machine that is North America's electricity infrastructure. The North American power grid has been called the world's largest machine. The grid connects nearly every living soul on the continent; Americans rely utterly on the miracle of electrification. In this book, Julie Cohn tells the history of the grid, from early linkages in the 1890s through the grid's maturity as a networked infrastructure in the 1980s. She focuses on the strategies and technologies used to control power on the grid—in fact made up of four major networks of interconnected power systems—paying particular attention to the work of engineers and system operators who handled the everyday operations. To do so, she consulted sources that range from the pages of historical trade journals to corporate archives to the papers of her father, Nathan Cohn, who worked in the industry from 1927 to 1989—roughly the period of key power control innovations across North America. Cohn investigates major challenges and major breakthroughs but also the hidden aspects of our electricity infrastructure, both technical and human. She describes the origins of the grid and the growth of interconnection; emerging control issues, including difficulties in matching generation and demand on linked systems; collaboration and competition against the backdrop of economic depression and government infrastructure investment; the effects of World War II on electrification; postwar plans for a coast-to-coast grid; the northeast blackout of 1965 and the East-West closure of 1967; and renewed efforts at achieving stability and reliability after those two events.
This is a print on demand publication. A study of the inventor Reginald A. Fessenden who was born in 1866 in Canada. Although the core of his more public fame rests on his seminal contributions to wireless, the more than 200 patents he was granted cover an amazing range. In addition, Fessenden developed the concept of what is today termed amplitude modulated (AM) radio. He produced and improved upon equipment to demonstrate the principles involved, being the first individual to transmit voice and music over the air. He was the first to establish consistent two-way wireless commun. across the Atlantic Ocean. In the course of his wireless work, he was granted a patent for use of the heterodyne principle that became so important in the vacuum tube era of radio and beyond. Illus.
