Paperback. Etat : new. Paperback. An amazing book on faster than light flight! H. David Froning, a 30-year veteran engineer who worked on several designs for future space travel propulsion, gives us this exceptional compilation of his discoveries, struggles and experiences in the realm of faster than light space travel. Central to the concept of faster than light travel is that the vacuum of space itself (the spacetime metric) can be utilized in propulsion systems. "Engineering the vacuum," as this is called, involves discovering how space can be altered to provide energy/thrust for future spacecraft. Packed with diagrams, some of which show how, as a starship accelerates away from Earth, it disappears and reappears in only seconds. But during these seconds of disappearance, the ship, in effect, leaps high above space-time and over stupendous distances to reach speeds that are billions of times greater than light-speed. Lots of great material on quantum vacuum power, anti-gravity propulsion effects, the velocity of light in spacetime altered regions, effective mass in spacetime-altered regions, warp drives, and tons more!

Paperback. Etat : new. Paperback. Conversion of electrostatic energy from the air is an unexplored area of science, even though Benjamin Franklin invented the first electrostatic motor in 1748, which is detailed in this book so the reader can make his or her own. The earth's electric field, at over 100 volts per meter, is a natural source of electrostatic energy or in other words: free electricity. However, the utilization of that atmospheric electricity, with electrostatic motors and airborne antennas, has been an elusive and neglected art from the last century. With the earth's ionosphere charged up to almost 400 thousand volts (kilovolts), the author notes that the higher the antenna, the higher the voltage that is accessible for any electrostatic motor. Professor Oleg Jefimenko, an amazing genius, physicist, and inventor, wrote this unique book describing his experiments with many electrostatic motors. He carefully documented each one with drawings and photos, explaining their construction and materials used. In this new edition, a few of Jefimenko's articles are added that will help the reader to construct his/her own electrostatic motor and thereby experiment with free electricity from the earth's atmosphere. This is an exciting book to read and the history is surprising. encouraging the reader to learn more, try to build one, and share the knowledge.

Paperback. Etat : New. The papers collected in this volume are a product of the second conference on Ireland's Great Hunger held at Quinnipiac University in 2005. That conference, focused on the themes of representation and preservation, brought together forty-five scholars from around the world to discuss various aspects of the Famine and its aftermath. Following the conference, the complete An Gorta Mór collection of Quinnipiac's famine commemorative art was placed on display for the first time in the University's Alumni Hall. The An Gorta Mór collection is on permanent display in the University's Arnold Bernhard Library and in other buildings across the University's Mount Carmel campus. This volume, focused on the theses of relief, representation, and remembrance, contains essays from a broad range of disciplines including works of history, literary criticism, anthropology, and art history.…
