I have read many theories and claims of how the Giza pyramids were built, and this one looks to be quite simple. He's Irish, and a Navy guy Doc, so he can't be all hot air, can he? Grin

Ancient mystery solved? Taft man says ?Murphy Mover' explains pyramids

January 19, 2007

     A retired navy man's musings on riding a backyard swing as a young boy gave him the idea for an invention that he says can explain one of histories enduring mysteries - the construction of the great pyramids of Egypt.

     James Murphy said his Apex Delivery and Lifting System - or Murphy Mover - is more than just an explanation. It's a nearly energy free way of lifting and moving large objects. It doesn't take much power and doesn't need any major outside energy - just gravity.

     The problem is getting it publicized. He's built small versions of the Murphy Mover, but would like to get a grant to get the funding to build and operate a large scale one.

     ?If you have the most valuable nickel in the world, and if nobody knows about it, it's just worth a nickel? he said.
     That's the hold up for Murphy's invention, which he has demonstrated and shown to several experts. While no one calls it an unqualified success, no one has laughed it off either.

     They do want to see some more proof. So does Murphy.

     He's trying to get a scientific paper on the Murphy Mover published to attract the attention that could lead to a grant to demonstrate his theory and models.

     Murphy is looking for someone with an engineering or technical background to help him write an article for publication in a robotics magazine.
  (If you are interested in helping out, contact Murphy at 763-1925 or email him at www.dlzdyno@aol.com)

     Murphy came across his idea reminiscing about riding his swing set as a young boy. As he swung higher and higher, the swing set started moving -- frightening to a young boy, but a revelation to an inventor.

     ?I would swing so high that the back legs would come off the ground, then the front legs would come off the ground.?
     Years later, as he looked back on it, he realized what was happening - gravity acting on his weight made the swing set walk.

     He mused on that thought and ended up with his invention, the Murphy Mover.

     He said that the size of the mover can be increased to move stones or blocks weighing thousands of pounds just as easily as the small model he demonstrates with only a piece of a brick swinging in it.
     ?The principle is the same whether you're a third grader weighing 45 pounds or it's a stone weighing 3,000 pounds,? he explains.

     He has shown his invention to a scientist at the Jet Propulsion Lab in Pasadena and to an Egyptologist.

     While neither has given it an unqualified endorsement, they are intrigued by his invention and his theory.
     Paul Backes, the JPL professor, told Murphy ?he'd never seen anything like it before.?

     Murphy's invention is something unique - like a four-sided pyramid, somewhat reminiscent of the swing set that originally inspired him.

     He can demonstrate how the concept operates with a small model he has, using a piece of a brick suspended in the Murphy Mover, he swings the brick, which starts the lifting system moving.

Hmmm. Another retired engineer. Remember what I posted about these guys?

It was not necessary to lift the blocks, so he is trying to solve a non-existent problem.

It reminds me of my father telling the family how mysterious the pyramids were, for they were decorated inside, yet there was no sign of lamp black. He had visited Egypt in the 1930s by liner, over-flown the pyramids and been most impressed.

The easy way to build the pyramids was with earthen ramps. As the structure gets taller, so the ramps are extended. The corridors and rooms are open to the sky as they are built, so sunlight obviates the need for lamps.

The blocks would have been drawn up the ramps by teams pulling and pushing, using rollers to bear the load.

A calculation has been done for labour and time. I cannot remember the details, though the result was surprisingly few people and years.

The Hollywood epic has slaves doing the work. I may be wrong, but I think that the evidence is for paid, professional labour. I have read accounts of the lives of the builders and if I recall, their records are quite detailed.

The lifting device illustrated here is very similar, if not identical, to that used by engineers of the Roman army.

   I recall hearing about this theory when it was first proposed, and have seen no corroboration until now. The ramp theory is referred to, with an indication that it is problematical, but the problems are not detailed. The biggest problem with the ramp theory is that there must be archaeological evidence of the ramp/s, but none exists. What was conclusive to the scientist who first proposed this theory was the fact that he found donkey hair inside of pyramid 'stones' he studied. Twenty years has brought many huge advances to science's ability to understand the past more accurately. As I don't see how this new study can be found to be wrong, this is where I will rest. No more theories of nonexistent problems, I promise.  Grin

   This paragraph really delighted me for two reasons, one of which I have touched upon before here. Diotomaceous earth is something I have used in the past as a parasitic treatment for animals, it is unbeatable, and well known in the certified organic community.

"The basic raw materials used for this early form of concrete - limestone, lime, and diatomaceous earth-can be found virtually anywhere in the world," he adds. "Replicating this method of construction would be cost effective, long lasting, and much more environmentally friendly than the current building material of choice: Portland cement that alone pumps roughly 6 billion tons of CO2 annually into the atmosphere when it's manufactured."


   The Surprising Truth Behind the Construction of the Great Pyramids

By Sheila Berninger, and Dorilona Rose - 18 May 2007

   "This is not my day job." So begins Michel Barsoum as he recounts his foray into the mysteries of the Great Pyramids of Egypt. As a well respected researcher in the field of ceramics, Barsoum never expected his career to take him down a path of history, archaeology, and "political" science, with materials research mixed in.

   As a distinguished professor in the Department of Materials Science and Engineering at Drexel University, his daily routine consists mainly of teaching students about ceramics, or performing research on a new class of materials, the so-called MAX Phases, that he and his colleagues discovered in the 1990s. These modern ceramics are machinable, thermal-shock resistant, and are better conductors of heat and electricity than many metals-making them potential candidates for use in nuclear power plants, the automotive industry, jet engines, and a range of other high-demand systems.

   Then Barsoum received an unexpected phone call from Michael Carrell, a friend of a retired colleague of Barsoum, who called to chat with the Egyptian-born Barsoum about how much he knew of the mysteries surrounding the building of the Great Pyramids of Giza, the only remaining of the seven wonders of the ancient world.

   The widely accepted theory-that the pyramids were crafted of carved-out giant limestone blocks that workers carried up ramps-had not only not been embraced by everyone, but as important had quite a number of holes.

Burst out laughing

   According to the caller, the mysteries had actually been solved by Joseph Davidovits, Director of the Geopolymer Institute in St. Quentin, France, more than two decades ago. Davidovits claimed that the stones of the pyramids were actually made of a very early form of concrete created using a mixture of limestone, clay, lime, and water.

   "It was at this point in the conversation that I burst out laughing," says Barsoum. If the pyramids were indeed cast, he says, someone should have proven it beyond a doubt by now, in this day and age, with just a few hours of electron microscopy.

   It turned out that nobody had completely proven the theory...yet.

   "What started as a two-hour project turned into a five-year odyssey that I undertook with one of my graduate students, Adrish Ganguly, and a colleague in France, Gilles Hug," Barsoum says.

   A year and a half later, after extensive scanning electron microscope (SEM) observations and other testing, Barsoum and his research group finally began to draw some conclusions about the pyramids. They found that the tiniest structures within the inner and outer casing stones were indeed consistent with a reconstituted limestone. The cement binding the limestone aggregate was either silicon dioxide (the building block of quartz) or a calcium and magnesium-rich silicate mineral.

   The stones also had a high water content-unusual for the normally dry, natural limestone found on the Giza plateau-and the cementing phases, in both the inner and outer casing stones, were amorphous, in other words, their atoms were not arranged in a regular and periodic array. Sedimentary rocks such as limestone are seldom, if ever, amorphous.

   The sample chemistries the researchers found do not exist anywhere in nature. "Therefore," says Barsoum, "it's very improbable that the outer and inner casing stones that we examined were chiseled from a natural limestone block."

   More startlingly, Barsoum and another of his graduate students, Aaron Sakulich, recently discovered the presence of silicon dioxide nanoscale spheres (with diameters only billionths of a meter across) in one of the samples. This discovery further confirms that these blocks are not natural limestone.

Generations misled

   At the end of their most recent paper reporting these findings, the researchers reflect that it is "ironic, sublime and truly humbling" that this 4,500-year-old limestone is so true to the original that it has misled generations of Egyptologists and geologists and, "because the ancient Egyptians were the original-albeit unknowing-nanotechnologists."

   As if the scientific evidence isn't enough, Barsoum has pointed out a number of common sense reasons why the pyramids were not likely constructed entirely of chiseled limestone blocks.

   Egyptologists are consistently confronted by unanswered questions: How is it possible that some of the blocks are so perfectly matched that not even a human hair can be inserted between them? Why, despite the existence of millions of tons of stone, carved presumably with copper chisels, has not one copper chisel ever been found on the Giza Plateau?

   Although Barsoum's research has not answered all of these questions, his work provides insight into some of the key questions. For example, it is now more likely than not that the tops of the pyramids are cast, as it would have been increasingly difficult to drag the stones to the summit.

   Also, casting would explain why some of the stones fit so closely together. Still, as with all great mysteries, not every aspect of the pyramids can be explained. How the Egyptians hoisted 70-ton granite slabs halfway up the great pyramid remains as mysterious as ever.

   Why do the results of Barsoum's research matter most today? Two words: earth cements.

   "How energy intensive and/or complicated can a 4,500 year old technology really be? The answer to both questions is not very," Barsoum explains. "The basic raw materials used for this early form of concrete-limestone, lime, and diatomaceous earth-can be found virtually anywhere in the world," he adds. "Replicating this method of construction would be cost effective, long lasting, and much more environmentally friendly than the current building material of choice: Portland cement that alone pumps roughly 6 billion tons of CO2 annually into the atmosphere when it's manufactured."

   "Ironically," says Barsoum, "this study of 4,500 year old rocks is not about the past, but about the future."
