Design or build a battery-powered electric bicycle

For much of the world, bicycles are a transportation mainstay. Electric bicycles----powered by a rechargeable battery pack----are proven to deliver the highest possible energy efficiency, even compared to pedal bikes. A transportation alternative to fossil fuels, electric bicycles are fast catching on, in part because they don't require factory assembly. End-users can easily construct them with available components.

The text reveals important techniques, data, and examples that allow readers to judge various propulsion setups----used in both home- and factory-made bikes----and estimate speed and travel distance for each. Numerous charts clearly present the costs, benefits, and trade-offs between both commercial and user-converted models.

Key features include: Estimating motor-performance for wind, hill, and cruising power requirements Estimating battery capacity and a thorough description of battery charging Motor and motor-control options Evaluating motor-to-wheel coupling options Placement of propulsion components Configurations and performance How systems-engineering techniques can produce electric-bicycle designs that have long travel range and low life-cycle cost Testing Developments to watch

A comprehensive resource for harnessing innovation, Electric Bicycles is the definitive practical guide to taking full advantage of this exciting alternative energy technology.

Concise, accurate, in-depth definitions of all key terms and concepts in organic chemistry

The language of organic chemistry embodies a unique set of concepts and nuanced meanings. For more than a quarter of a century, students and professionals seeking to acquire a quick and thorough familiarity with that language have turned to The Vocabulary of Organic Chemistry.

No mere alphabetical listing, this one-of-a-kind reference comprises eighteen topical chapters covering key subject areas in organic chemistry and related fields--from atomic orbital theory to polymer chemistry, nuclear magnetic resonance spectroscopy to the chemical utilization of fossil fuels. Related terms and concepts--such as catalyst and zoelite--appear in the same chapter and in close proximity to one another, thus placing them in context and making it easier for readers to grasp fine distinctions. And throughout, specific examples and clearly drawn structures help to clarify key concepts.

Revised and updated for the twenty-first century, The Vocabulary and Concepts of Organic Chemistry, Second Edition offers: Hundreds of terms and concepts--fully explained and in context Myriad examples and illustrations Brief introductory narratives that help place subject areas in historical perspective New sections on the four common spectroscopies (NMR, IR, Mass, UV) and photochemistry

Written by an author team with nearly one and a half centuries of combined teaching and research experience, this book is an ideal study aid for undergraduate and graduate students and a valuable professional resource for chemists who want to brush up on specific areas in organic chemistry.

A distillation of technical material culled from key radar publications and conferences that have occurred over the past five years, this book provides access to the answers to common design problems with designer crib sheets. William Morchin has also written Airborne Early Warning Radar.
