Roamer,
Glad you liked the sketchup work. The idea of eliminating the central shaft came to me because, the way a normal stator and rotor are set up, you need commutators  to keep the current flowing in one direction as the shaft rotates. With this setup, although it looks like three sets of windings, they are all connected to each other for just one phase of DC. As the annulus rotates, the collapsing fields, regardless of magnetic polarity (a different ball of wax from electrical polarity), will generate DC in one direction only because the direction the fields are collapsing in is constant. To reverse the current, you would have to spin the annulus in the other direction. When I took that industrial electronics and robotics course, I rigged up a very crude emf induction setup by gluing a bunch of magnets to a plastic wheel on a shaft. I used coil wire (which is insulated like generator windings) and placed the coils near the outside of the spinning plastic wheel with magnets. My meter leads on the ends of the coil wire showed a weak but measurable voltage and current (DC). I figured, if I could wrap the coil around those magnets, I'd get more juice but that is impossible with a central shaft so that's where I came up with housing the magnets annulus and house it with one long continuous insulated winding. That way I could dispense with commutators and brushes. The reliability and longevity issues would be in the drive and mechanical transmission elements like bearings, gears and the toothed belt. The toothed belt would have to be built somewhat like a chain that can be disconnected at one point to remove and replace because, once the windings are in place, there is no way to take that toothed belt off without destroying the windings or breaking the belt.

I break with the traditional concept that the magnets are still and the coil does the rotating. I flip that on its head to get rid of commutators and brushes. I am still dealing with just one phase winding although I assume other phases could be introduced. I'm still at proof of concept somewhere bejond my plastic wheel with the coiled wire near the peripheral magnets going by.

I'll check out those links you gave.  :emthup:

agelbert, I think you might have to try to explain your idea first.  Indeed I'm not an electrical engineer,  and the principles you are looking for require a fair amount of math and basic electrical concepts to accurately describe. Your question may not be exactly what you are looking for, maximum electron flow does not really seem to be a sensible question to ask when designing a generator.  Off the top of my head I'd say that the generator you are describing works by having the windings intercept a moving magnetic field.  That strength of the induced electric field in the windings is proportional to the strength of the moving magnetic field which is intersected.   The magnetic field falls varies inversely over the distance between the windings and the moving magentic field (typically a rotor could also be a linear oscillating magentic or even a stationary oscillating induced field).  So what that means is that the further the windings are from the field the more windings you need to fully harness the power which the magnetic source is capable of transmitting into electricity.  In other words the further away the windings are the more expensive it is to build an effecient generator.  As for the effects of insulation I am not certain how much this reduces the magnetic permuabilty

RE,
My hedges are multi pronged.  I've relocated to an industry that should be stable to the end of this order (undisclosed position at coal fired power plant) in a remote location. I got primitive living skills, modern camping and hunting skills,  am on paleo  diet and exercise protocol (best health insurance you can get), and am now taking to the hobby of designing integrated bugout machines, starting with the SUV I got.  All of those I enjoy though just for the sake of learning and self reliance.  Even the job in the remote location actually has more to do with my liking remote places and solitude than any sort of coherent strategy/
I am actively designing and researching integrated solar energy solutions, and best practice farming techniques.  Next year I hope to build some demonstration projects and systems. I really enjoy this and once I get stable in my new job I hope to share some of my work on this subject.
By far and away the biggest hedge, if you could call it that, is that I have made more peace with my mortality and the mind boggling conundrums we humans are prone to make.  I now seeing things from very very long cycles and no longer get so worked up over our immense near term mistakes.  From that lens too I actually have been surprised to find I have more faith in the earth experiment in human sentience than I previously had. No one on planet earth has unlimited power, the illuminati are only empowered by our collective greed and ignorance and these will wane as we all start to suffer more.   

The end is and always been at hand for many people on earth,

Obsolescence of the Obsolete: Where Airplanes Go to Die

Where America's Airplanes Go To Die

Tyler Durden's picture



 

Davis–Monthan Air Force Base is located in Tucson, Arizona. It occupies an area of over 10 square kilometers, equal to roughly 1,870 football fields. The base is the location of the Air Force Materiel Command's 309th Aerospace Maintenance and Regeneration Group, or AMARG in short. It is also known as the "boneyard." 

With the area's low humidity in the 10%-20% range, meager rainfall of 11" annually, hard alkaline soil, and high altitude of 2,550 feet, it has the "just right" conditions to avoid corrosion and not to need paving when moving massive objects. It has emerged as the perfect venue for one thing: the largest aircraft boneyard in the world, with a typical inventory of more than 4,400 aircraft.

Allowing the aircraft to be naturally preserved for cannibalization or possible reuse, Davis-Monthan is the logical choice for a major storage facility. The geology of the desert allows aircraft to be moved around without having to pave the storage areas.

AMARG's role in the storage of military aircraft began after World War II, and continues today.

Interactive map of AMARG as seen in the most recent Google maps satellite overflight:

Follows the brief  story of the world's largest military airplane boneyard.

AMARG was established in 1946 as the 4105th Army Air Force Unit to house B-29 and C-47 aircraft. By May of 1946, more than 600 B-29 Superfortresses and 200 C-47 Skytrains had been moved to Davis-Monthan. Some were preserved and returned to action in the Korean War, others were scrapped.

In 1948, after the Air Force's creation as a separate service, the unit was renamed the 3040th Aircraft Storage Depot.

In February of 1956, the first Convair B-36 Peacemaker aircraft arrived at Davis-Monthan AFB for scrapping. All of the fleet of 384 Peacemakers would ultimately be dismantled except for four remaining B-36 survivors saved for air museums.

In 1965, the depot was renamed the Military Aircraft Storage and Disposition Center (MASDC), and tasked with processing aircraft for all the US armed forces (not just the Air Force). The U.S. Navy had operated its own boneyard at Naval Air Station Litchfield Park at Goodyear, Arizona for Navy, Marine and Coast Guard aircraft. In February 1965, some 500 aircraft were moved from Litchfield Park to Davis-Monthan AFB. NAS Litchfield Park was finally closed in 1968.

The last Air Force B-47 jet bomber was retired at the end of 1969, and the entire fleet was dismantled at Davis-Monthan except for about 30 Stratojets which were saved for display in air museums.

In the 1980s, the center began processing ICBMs for dismantling or reuse in satellite launches, and was renamed the Aerospace Maintenance and Regeneration Center (AMARC) to reflect the expanded focus on all aerospace assets.

In the 1990s, in accordance with the START I treaty, the center was tasked with eliminating 365 B-52 bombers. The progress of this task was to be verified by Russia via satellite and first-person inspection at the facility. Initially, the B-52s were chopped into pieces with a 13,000-pound guillotine winched by a steel cable, supported by a crane. Later on, the tool of choice became K-12 rescue saws. This more precise technique afforded AMARG with salvageable spare parts.

In May 2007, command of AMARG was transferred to the 309th Maintenance Wing, and the center was renamed the 309th Aerospace Maintenance and Regeneration Group.

* * *

Today, Davis-Monthan is the location of the 309th Aerospace Maintenance and Regeneration Group (AMARG), the sole aircraft boneyard and parts reclamation facility for all excess military and government aircraft. Aircraft from the Air Force, Navy, Marine Corps, Coast Guard, NASA and other government agencies are processed at AMARG, which employs 550 people, almost all civilians.

It is the largest airplane boneyard in the world.

Another role of AMARG is to support the program that converts old fighter jets, such as the F-4 Phantom II and F-16, into aerial target drones. It also serves as an auxiliary facility of the National Museum of the United States Air Force, and stores tooling for out-of-production military aircraft.

AMARG's typical inventory comprises more than 4,400 aircraft, which makes it the largest aircraft storage and preservation facility in the world.

AMARG is a controlled-access site, and is off-limits to anyone not employed there without the proper clearance. The only access for non-cleared individuals is via a bus tour which is conducted by the nearby Pima Air & Space Museum.

That largely covers US warplanes, but what about commercial jets? As the Bossroyal blog shows, many if not most disused, aging or obsolete airliners, end up in the Californian desert, 150 kilometres outside Los Angeles, at the Mojave Air and Space Port.

In addition to being the “world’s premier civilian aerospace test center”, the Mojave Port is also one of America’s most well-known ‘aircraft boneyards’, and just like in Arizona, the dry Nevada conditions are ideal for minimising corrosion on jets looking for new owner-operators, or just looking for a quiet place in which to rust in peace.

Hundreds, if not thousands, of junked or stored airliners form a surreal view amid the harsh landscape in Mojave, and all the major commercial airliner manufacturers – Boeing, Airbus, McDonnell Douglas and Lockheed Martin – are well represented.

For plane buffs, Mojave and facilities like it dotted across the US provide both a history of commercial aviation as well as a damning judgement on modern day consumerism.  In the aftermath of the September 11, 2001 terrorists attacks, for example, the demand for air travel hit massive turbulence, and many major airlines were forced to mothball some of their fleet due to lack of demand. Many of them ended up at Mojave, and many remain there today, waiting to spread their wings once more.

In addition to the boneyards shown above, there are many other active and inactive places where thousands of airplanes and fighter jets have been stored across the continental US. The annotated map below is a handy reference to tracking down most of them.

How much healthcare could we have bought with the money it took to build all that shit?

No wonder the country is fucking broke. What incredible waste. Now to that, add all the naval vessels that have been scrapped, and all the tanks and missiles and nukes. And to that add the salaries of all the people we have screwing around in 140 other sovereign foreign countries.

What makes the desert beautiful is that somewhere it hides a well.

Some interesting themes going on in this article, from the social aspects of the internet, to the nature of intellectual debate.  In the real world as on the internet, people drift in and out of our lives, observing the rule that nothing is static.  While there is some healthy exchange of thoughts and information here as in other venues, as you pointed out humans tend to talk AT each other, instead of talking together.  How can any significant understanding come from a process of "I defy you, you defy me?"  I see this is in part caused by not listening, or in this case not reading, as well as our preconceived notions against which the information is evaluated. 

As you said there are bigger themes that the blogosphere and commentariat tend to agree upon despite their specific brand of doomTM.  I would hazard a guess that the core themes are
