Power beaming is the ability to move energy without moving or employing mass between an energy input and energy output. It is an emerging technology that could reshape how we generate and distribute energy and how our devices and autonomous systems are powered.This comprehensive compendium provides the foundation needed for researchers, technology developers, and end users to understand the promise and challenges for power beaming. By establishing a common nomenclature and conceptual approach to the analysis and assessment of power beaming systems, this unique reference text provides a true status of advancements in the field, and lays the groundwork for fruitful future research and applications.

Recounts the story of unmanned aircraft research and development at the Naval Research Laboratory (NRL) Vehicle Research Section (VRS). This title features vehicles that have charted the course of unmanned aircraft history in the late 20th and early 21st centuries. It is a contribution to the history of aircraft design and development.

Addressing all those interested in the history of American science and concerned with its future, a leading scholar of public policy explains how and why the Office of Naval Research became the first federal agency to support a wide range of scientific work in universities. Harvey Sapolsky shows that the ONR functioned as a "surrogate national science foundation" between 1946 and 1950 and argues that its activities emerged not from any particularly enlightened position but largely from a bureaucratic accident. Once involved with basic research, however, the ONR challenged a Navy skeptical of the value of independent scientific advice and established a national security rationale that gave American science its Golden Age. Eventually, the ONR's autonomy was worn away in bureaucratic struggles, but Sapolsky demonstrates that its experience holds lessons for those who are committed to the effective management of science and interested in the ability of scientists to choose the directions for their research. As military support for basic research fades, scientists are discovering that they are unprotected from the vagaries of distributive politics. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
