Previously, he worked for the New York State Power Authority and the New York State Energy Research and Development Authority, where he helped develop, market, and manage electric and hybrid vehicle programs serving New York State and the New York metropolitan area. Seth is the consulting editor for a series of upcoming titles called the “Green Guru Guides,” which focus on implementing environmentally friendly technologies and making them work for you. Bob Brant was the author of the first book, and some might say ahead of his time in his passion to convert to electric. The first edition of this book was published in 1993. While there have obviously been updates and technological advances since that time, many of the concepts in that first book are still in use today. Bob grew up in New York City, got a BSEE, and worked on NASA projects such as Apollo, Lunar Excursion Module, and the Earth Resources Technology Satellite. He then went on to get an MSEE and MBA, and worked for a company that worked on the Lunar Rover. Bob was always fascinated with every electric vehicle breakthrough, was convinced of its personal and environmental benefits, and was curious why stronger steps had not been taken to make electric vehicles a reality. Seth Leitman and everyone at McGraw-Hill would like to think of this updated edition as a tribute to Bob and other forward thinkers like him. Copyright © 2009 by The McGraw-Hill Companies, Inc.
