paperback. Zustand: Good. Our good condition books are generally good for reading but not for gifting or collecting. They could have imperfections such as creasing, fanning, inscriptions, margin notes, yellowing, staining on edge or cover or pages, bumps, scuffs, etc etc (sometimes multiple of these). It's a wide category that encompasses anything that isn't almost-new down to anything that is slightly better than poor. We would NOT recommend gifting Good books - these should be considered reading copies. Our books are dispatched from a Yorkshire former cotton mill. We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing. If you're looking for an exact edition please don't order (at least not without checking with us first, although we don't always have time to check). We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only.…

Paperback. Zustand: Good. In the 1940s, the physician and natural scientist Dr. Wilhelm Reich claimed discovery of a new form of energy which charged up living organisms and also existed in the open atmosphere and in high vacuum. Reich's laboratory and clinical findings indicated this new energy, which he called the orgone, could be photographed and measured, and had powerful life-positive biological effects. Reich trained other scientists and physicians in his findings, and together they set about applying the inexpensive orgone treatment methods - using a device called the orgone energy accumulator - against various illness, including cancer, with remarkably good results. His published findings shocked the scientific world of his day, however, ultimately leading to numerous smear articles in the popular press, and trumped-up charges by a power-drunk Food and Drug Administration. The FDA investigation lead to a court trial of much greater significance than the better-known Scopes Monkey Trial. Ignoring Reich's evidence and declaring the orgone energy does not exist, US Courts ordered all his books on the orgone subject to be burned, and banned from further circulation. Reich was also thrown into prison, where he died. His work was nearly forgotten except by a small group of supporters. In this Handbook, former university professor Dr. James DeMeo examines Reich's evidence and reports on his own observations and laboratory experiments, which have repeatedly confirmed the reality of the orgone phenomenon. DeMeo also surveys the observations and experiments of others, including controlled cancer mice experiments, double-blind university studies, and clinical reports from physicians working in private clinics where use of Reich's controversial orgone energy accumulator proceeds today. This Handbook also gives a warning about low-level atomic and electromagnetic radiations, as from nuclear power plants, power-line fields and cell-phones, along with advice on measurement and protection against such toxic energy. Also discussed is the subject of healing waters, or Living Waters from natural hot springs, a form of energy medicine which once was widely used in North America before the rise of the authoritarian MD-hospital system and the powerful federal bureaucracy of the FDA. Dr. DeMeo also gives detailed construction plans for people to build their own orgone energy blankets and accumulators, which are inexpensive and simple to construct, though requiring specific direction as to their materials and environments. This is the Third Revised and Expanded 2010 Edition of the Orgone Accumulator Handbook, nearly 100 pages larger than prior editions and carrying a Foreword by Dr. Eva Reich (the daughter of Dr. Wilhelm Reich), along with many photos, diagrams and charts. It is updated to address new issues about the best materials for orgone accumulator and blanket construction. An Appendix is also included, identifying the similarities of Reich's orgone energy to the cosmic ether and dark matter of modern physics. A section is also included providing New Evidence on the Persecution of Reich, along with an extended bibliography, index and many weblinks for added information. It has many new photos and materials extracted from Dr. DeMeo's publications verifying the reality of the orgone energy, and is a must have for all those interested in the issue of life-energy, subtle-energy or energy-medicine research. This is an excellent introduction to a major scientific discovery, organized for the educated layperson but with sufficient detail and citations to stimulate the curiosity of the open-minded physician and scientist. …
