The world is never finished catching up with Vaclav Smil. In his latest and perhaps most digestible book, Invention and Innovation, the prolific author—a favorite of Bill Gates—pens an insightful and fact-filled jaunt through the history of human invention. Impatient with the hype that so often accompanies innovation, Smil offers in this book a clear-eyed corrective to the overpromises that accompany everything from new cures for diseases to AI.

What makes the modern world work? The answer to this deceptively simple question lies in four "grand transitions" of civilization - in populations, agriculture, energy, and economics - that have transformed the way we live. 

In this intriguing business novel, which illustrates state-of-the-art economic theory, Alex Rogo is a UniCo plant manager whose factory and marriage are failing. To revitalize the plant, he follows piecemeal advice from an elusive former college professor who teaches, for example, that reduction in the efficiency of some plant operations may make the entire operation more productive. Alex's attempts to find the path to profitability and to engage his employees in the struggle involve the listener; and thankfully the authors' economic models.

In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses.

For generations, everything has been getting faster, better, and cheaper. Finally, we reached the point that almost anything you could ever want could be sent to your home within days - even hours - of when you decided you wanted it. America made that happen, but now America has lost interest in keeping it going.
