Once a blue-collar outpost, Seattle, home to Microsoft, Amazon, and hundreds of startups, transformed into one of the world’s major innovation hubs in less than twenty years. As other cities try to solve the riddle of creating vibrant economies, many have looked to Seattle as a model for tech-driven urban renaissance. However, that success comes with skyrocketing housing costs, increasing homelessness, public safety concerns, persistent racial inequality, and a widening gap between the haves and have-nots. Against that backdrop, big tech has become a popular target. Tom Alberg, a venture capitalist who was one of the first investors in Amazon, draws on his experience in Seattle’s tech boom to offer a vision for how cities and businesses can build a brighter future together. He explores ways that cities can soar to prosperity by creating the conditions that encourage innovation. Like flywheels, livable cities generate momentum by drawing creative citizens who launch businesses. Success attracts more talent, energizing local economies and accelerating further innovation. Alberg emphasizes the importance of city governments and tech companies partnering to address civic challenges. He reflects on why the benefits of the tech boom have not been distributed equally and what business and government leaders must do differently to ensure inclusive growth. The book also examines success stories from smaller cities and their lessons for other up-and-coming tech hubs. Demonstrating the need for innovative thinking that encourages livability alongside economic growth, Flywheels is timely reading for everyone from mayors to business leaders to engaged citizens.

A companion guidebook to the number-one bestselling Good to Great, focused on implementation of the flywheel concept, one of Jim Collins’ most memorable ideas that has been used across industries and the social sectors, and with startups. The key to business success is not a single innovation or one plan. It is the act of turning the flywheel, slowly gaining momentum and eventually reaching a breakthrough. Building upon the flywheel concept introduced in his groundbreaking classic Good to Great, Jim Collins teaches readers how to create their own flywheel, how to accelerate the flywheel’s momentum, and how to stay on the flywheel in shifting markets and during times of turbulence. Combining research from his Good to Great labs and case studies from organizations like Amazon, Vanguard, and the Cleveland Clinic which have turned their flywheels with outstanding results, Collins demonstrates that successful organizations can disrupt the world around them—and reach unprecedented success—by employing the flywheel concept.

Seventeen-year-old Delilah Green wouldn't have chosen to do her last year of school this way, but she figures it's working fine. While her dad goes on a trip to fix his broken heart after her mom left him for another man, Del manages the family cafe. Easy, she thinks. But what about homework? Or the nasty posse of mean girls making her life hell? Or her best friend who won't stop guilt-tripping her? Or her other best friend who might go to jail for love if Del doesn't do something? But really, who cares about any of that when all Del can think about is beautiful Rosa who dances every night across the street. . . . Until one day Rosa comes in the cafe door. And if Rosa starts thinking about Del, too, then how in the name of caramel milkshakes will Del get the rest of it together?

Kinetic Energy Storage: Theory and Practice of Advanced Flywheel Systems focuses on the use of flywheel systems in storing energy. The book first gives an introduction to the use of flywheels, including prehistory to the Roman civilization, Christian era to the industrial revolution, and middle of the 19th century to 1960. The text then examines the application of flywheel energy storage systems. Basic parameters and definitions, advantages and disadvantages, economic considerations, road vehicle applications, and applications for fixed machines are considered. The book also evaluates the flywheel, including materials, radial bar and filament flywheel, composite material disc flywheel, rotor stress analysis, and flywheel testing. The text also discusses housing and vacuum systems and flywheel suspension and transmission systems. Aerodynamic drag on wheels, burst containment, types of bearings, rotor dynamics, dampers, and types of transmissions are described. The text is a vital source of information for readers wanting to explore the composition and functions of flywheels.

The small-block Chevrolet engine is the most popular engine in the world among performance enthusiasts and racers. But with its popularity come certain problems, and this book is your step-by-step go-to manual.

Manufacturing readiness of composite rotors and certification of flywheels depend in part on the maturity of nondestructive evaluation (NDE) technology for process optimization and quality assurance, respectively. Capabilities and limitations of x-ray-computed tomography and radiography, as well as advanced ultrasonics were established on NDE ring and rotor standards with EDM notches drilled holes. Also, intentionally seeded delamination, tow break, and insert of bagging material were introduced in hydroburst-rings to study the NDE detection capabilities of such anomalies and their effects on the damage tolerance and safe life margins of subscale rings and rotors. Examples of possible occurring flaws or anomalies in composite rings as detected by NDE and validated by destructive metallography are shown.

Based on the study of energy storage this book comprehensively covers the various types of secondary storage systems (storing energy until it is needed), and discusses the multidisciplinary problem of choice of their types and parameters.

The Challenge Built to Last, the defining management study of the nineties, showed how great companies triumph over time and how long-term sustained performance can be engineered into the DNA of an enterprise from the verybeginning. But what about the company that is not born with great DNA? How can good companies, mediocre companies, even bad companies achieve enduring greatness? The Study For years, this question preyed on the mind of Jim Collins. Are there companies that defy gravity and convert long-term mediocrity or worse into long-term superiority? And if so, what are the universal distinguishing characteristics that cause a company to go from good to great? The Standards Using tough benchmarks, Collins and his research team identified a set of elite companies that made the leap to great results and sustained those results for at least fifteen years. How great? After the leap, the good-to-great companies generated cumulative stock returns that beat the general stock market by an average of seven times in fifteen years, better than twice the results delivered by a composite index of the world's greatest companies, including Coca-Cola, Intel, General Electric, and Merck. The Comparisons The research team contrasted the good-to-great companies with a carefully selected set of comparison companies that failed to make the leap from good to great. What was different? Why did one set of companies become truly great performers while the other set remained only good? Over five years, the team analyzed the histories of all twenty-eight companies in the study. After sifting through mountains of data and thousands of pages of interviews, Collins and his crew discovered the key determinants of greatness -- why some companies make the leap and others don't. The Findings The findings of the Good to Great study will surprise many readers and shed light on virtually every area of management strategy and practice. The findings include: Level 5 Leaders: The research team was shocked to discover the type of leadership required to achieve greatness. The Hedgehog Concept (Simplicity within the Three Circles): To go from good to great requires transcending the curse of competence. A Culture of Discipline: When you combine a culture of discipline with an ethic of entrepreneurship, you get the magical alchemy of great results. Technology Accelerators: Good-to-great companies think differently about the role of technology. The Flywheel and the Doom Loop: Those who launch radical change programs and wrenching restructurings will almost certainly fail to make the leap. “Some of the key concepts discerned in the study,” comments Jim Collins, "fly in the face of our modern business culture and will, quite frankly, upset some people.” Perhaps, but who can afford to ignore these findings?
