To achieve great things, you have to be willing to take risks-and as Edison's Concrete Piano reveals, some of the most famous names in history experienced plenty of flops and face-plants in the course of their careers. Thomas Edison, for example, not only revolutionized the world with the light bulb, but also designed a concrete piano, a nonoperational helicopter made from box kites and piano wire, and a machine to speak to the dead. Alexander Graham...

This book demonstrates how a piezoelectric actuator can be used as part of the actuation system in a circuit breaker mechanism. The design of circuit breaker could be simplified by the use of smart materials. A simpler mechanism requires fewer mechanical parts. This can improve reliability, reduce size, power consumption and manufacturing costs. It allows substantial miniaturization of these devices resulting in a completely new type of circuit breaker....

The design of circuit breakers is mainly based on experience rather than precise science. Empirical formulae can be used to determine dimensions of certain general types and the breaking capacity rating. Further developments will rely on new research of a scientific as well as a practical nature. This book, by a woman who has contributed to the development of electrical arc control in circuit breakers, provides new insight into arc root motion in...
