"Robert Zubrin is a true engineering genius like the heroic engineers of the past." -- Frederick Turner, American Enterprise Using nuts-and-bolts engineering and a unique grasp of human history, Robert Zubrin takes us to the not-very-distant future, when our global society will branch out into the universe. From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos. Sagan himself said of Zubrin's humans-to-Mars plan, " Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space , he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and field theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell's equations in free space, and suitable macroscopic models of polarized and magnetized matter. Special features * Covers the electromagnetism of moving bodies and the process of electromechanical energy conversion * Introduces a power-series technique for analyzing quasi-static fields and quasi-stationary systems * Emphasizes the synthesis of fields as opposed to the analysis of fields * Presents, in an appendix, the four-dimensional relativistic formulation of macroscopic electrodynamics recently developed by one of the authors (L. J. Chu)

This book presents, for the first time in one place, the results of the latest research regarding water balance covers for solid waste sites, along with case studies drawn from current field testing. Water Balance Covers for Waste Containment: Principles and Practice introduces water balance covers and compares them with conventional approaches to waste containment. The authors give detailed analysis of the fundamentals of soil physics and design issues, introduce applicable ecological concepts and revegetation practices, and then move on to construction, modeling, and maintenance. A viable alternative to conventional landfill cover systems, water balance covers (also known as store-and-release and evapotranspiration covers) cycle water from the soil to the atmosphere during growing season, minimizing the percolation of rainwater through the soil, and thus the production of leachate from land fill contents. This book will be valuable to practicing engineers, as well as regulatory analysts. --Book Jacket.
