AUTOGIROisa comprehensive book portraying the development workof the Autogiro Company of America and its licensees during the period 1928 through 1943. Thebook gives details on the design, various methods of construction and flight characteristics of each model of autogiro that was produced and test flown during the period. The text is complemented by numerous photographs and 3-view scale drawings.
This means that if the flywheel (which is red in the following photographs) is driven smoothly at constant speed, then there is no energy gain. However, if the drive is not smooth, then excess energy is drawn from the gravitational field. That energy increases as the diameter of the flywheel increases. It also increases as the weight of the flywheel increases. It also increases if the flywheel weight is concentrated as far out towards the rim of the flywheel as is possible. It also increases, the faster the impulses are applied to the system. Now take a look at the construction which Chas has used
Advancing the design even further, Phil has now produced an extremely clever design by introducing an additional DC motor generator coupled to the Prime Mover motor. The coupling is nominally mechanical with the two motors physically linked together with a belt and pulleys, but the electrical linking is such that the two motors will synchronise automatically if the mechanical linkage is omitted. I should like to express my thanks to him for sharing this information, diagrams and photographs freely.
Observant students of the disk turbine design might have wondered why some of Tesla's engines do not appear to use a labyrinth seal between the end disks and the corresponding engine casing end plates. After all, the patent drawings clearly show these seals and the accompanying text describes them at length. At the same time, photographs of the dual 200 H.P. turbine installed at the Edison Waterside plant in New York reveal an absence of this feature.
Tesla claimed to have observed the effects of the Colorado Springs transmitter at a distance of up to 600 miles. An advertising brochure for the World Telegraphy system claims the transmission of power around the globe in sufficient quantity to light incandescent lamps (50watts). Others report that a bank of 200 watt lamps, 50 watts each, were lit at a distance pf 26 miles 12,13 . The article in Century magazine shows photographs of an isolated extra coil powering and incandescent lamp as evidence of electrical vibrations transmitted to it through the ground from the oscillator 43 . However, this extra coil was most likely within the inductive field of primary transmitter, with the ground serving as a return path.
But of course, it is not just people interested in renewable energy that can benefit from understanding innovation diffusion. For example, companies that manufacture photographic film may want to know how fast digital cameras will diffuse and displace their products public health officials trying to introduce mosquito nets will want to know how to encourage more people to use more nets more quickly extension agents propagating the use of new seeds for enhanced crop yields will want to know how to encourage more farmers to sign on in the shortest possible period of time. Indeed, wherever somebody is in a race against time to either understand or accelerate the
Many people have given invaluable assistance and counsel during this journey of mine, and I wish to acknowledge them with profound thanks. To Tom Valentine, for aggressively pursuing the story of Ed Gray, for his excellent and accurate reporting, for his tremendously revealing photographs, and for his exceptional generosity in making his entire archive available to me. None of this would have happened without his contribution.
Much of this information and photographs of the original device can be found on the website 20by 20Michael 20Watson.htm where a paper by Michael Watson gives much practical information. For example, he states that an experimental set up which he made, had the 'A' coil with a resistance of 70 ohms and an inductance of 63 mH, the 'B' coil, wound with 23 AWG wire with a resistance of 4.95 ohms and an inductance of 1.735 mH, and the 'C' coil, also wound with 23 AWG wire, with a resistance of 5.05 ohms and an inductance of 1.78 mH.
Life on the American road in the Veggie Van was a nonstop, colorful adventure. At least one out of every four people who passed us on the highway waved, honked, or gave us a big smile. We often turned our heads to absentmindedly look at a passing vehicle only to see a camera flash from the passenger's side. In rest areas and parking lots, people gathered around the van, reading its messages, taking pictures of family members next to it, and including it in their summer vacation home movies. The first question people asked

It takes a lot of research to compile a history such as this. Through the more than twenty years that I have been putting it all together the following organizations and individuals have come forward with photographs and data to make it all possible. ABOUT THE PHOTOGRAPHS Researchers handle and view many hundreds of photographs in the course of their research. The photographers are often not identified. Photo services may no longer be in business, or the photographer may be deceased. Some of the photographs in AUTOGIRO are known to be made by Underwood and Underwood, Acme, Alfred DiLardi, Aero Service, Dalin Aerial Surveys. Othersare from collections of Pitcairn Co., Kellett, National Archives, The Smithsonian Institution, John Underwood, Warren Ship, Howard Levy, Driscol A, Nina, Bill Hannan, Ellsworth Thompson, A.W, Bayer, and the Author.

Some people are adamantly opposed to wind farms, most are neutral, and the rest are in favor. For those opposed, generally the visual impact is the most important concern 14 . The photo gallery of Stopillwind has before and after photos of wind farms. The ones most in favor of wind farms receive an economic return from the wind farm, whether directly or indirectly. The wind farm developer needs to do community education as soon as the project is official. Economic development in rural areas is very powerful from a political standpoint.

The next step is to turn the variable resistor to its minimum resistance position again. This causes the rotor to leave its previous maximum speed (about 1,700 rpm) and increase the speed again. As the speed starts increasing again, the variable resistor is once again gradually turned, increasing its resistance. This raises the rotor speed to about 3,800 rpm when the variable resistor reaches mid point again. This is probably fast enough for all practical purposes, and at this speed, even the slightest imbalance of the rotor shows up quite markedly. To go any faster than this requires an exceptionally high standard of constructional accuracy. Please remember that the rotor has a large amount of energy stored in it at this speed and so is potentially very dangerous. If the rotor breaks or a magnet comes off it, that stored energy will produce a highly dangerous projectile. That is why it is advisable, although not shown in the above photographs, to construct an enclosure for the rotor....

Hull Spiral-bound Published 1994 Our Price 27.50 (Special Order) Reviews The author, Richard L. Hull , May 14, 1997 What this book is about, and Who it is written for. The Colorado Spring Notes - No lit, are a collection of daily scientific journal entries written by Nikola Tesla during his experimentation with high voltage electrical resonant systems while in Colorado in 1899. This book is written specifically for the advancing Tesla coil builder who has a copy of the Colorado Springs Notes and finds them mysterious or disjoint. It is aimed at clearing up some of the unclear language and units used by Tesla in the late 19th century. His commentary is reviewed on a day by day basis and those items which relate to the modern tesla coil builder are made plain in modern scientific verbiage using more modern units of electrical measure. Owning the original Colorado Springs Notes is not really necessary, as the book is written in a flowing format which is self contained. If the...
Here is a description of each module's particular requirements and a photograph of its junction box. All the photographs (except Midway Labs concentrator) were shot by Mark Newell using the same lens at the same distance from the J-Box. All the resulting photographic prints were reduced by the same amount before printing here. This means that the relatively sizes of the boxes in these photos are a good indication of their relative real physical sizes.
