Caltech Team Raises 6900-Pound Obelisk, By Kite (caltech.edu) 209
Paintthemoon writes: "So, this crazed entrepreneur and Caltech buddies this weekend staged a successful test of using a 30-foot kite to raise a 6,900 pound concrete obelisk in the Mojave. The theory behind this is that the ancient Egyptians could have used such wind power to raise obelisks and build the pyramids ... " The article is from earlier this month. It's been a lot longer than that since scientists started trying to figure out how the Egyptians moved and righted some of their obelisks.

But as I remember, the large-scale test (30 ton obelisk) using the elaborate tilting mechanism failed when using man-power. There was a cylindrical log underneath the obelisk which they couldn't keep from being dragged instead of rolled (too much downward pressure from the weight of the obelisk). They eventually had to use an industrial crane to get the obelisk in place, which obviously was unavailable to Egyptians.
The sandbox test worked perfectly, and though it was a smaller obelisk (6-tons or so) it was done totally man-powered. The Egyptians have raised obelisks that weight up to 100 tons, and the sandbox theory seems the most likely one that could have been scaled up for obelisks of this size.

What happened in the past always gives an insight of which way to move ahead in the future. For example I was watching a tv show called Frontline on Friday in which the state of the world was being discussed, and how man has destroyed much of it (animals going extinct, plants, algae, etc.) and the scientist predicted that at the rate we're going with global warming, tree deforestation, fishing overkill, that the world is in some serious shit.
In Mongolia as it stands, many of the country's natural grass is barely growing due to the country's collapse, and the boom of farmers raising goats, and not switching to other parts of the land to allow the fields to grow back. In China they faced the same problem years ago, and now within the next 5 years they have to destroy hundreds of thousands of animals in order to avoid losing many resources.
Paleontologists explained how essential things are nowadays, how they're being destroyed, and how this compared to the repeating occurances of extinction with the dinosaurs, and other stuff like algeas, and crap like that.

There was also a separate experiment going on at the same time(although, with a minitaure obelisk) where a sand box was used.. It worked beatifully. They had a high platform with a sand box in front of it and as the sand was removed the obelisk tilted down gracefully onto it's place.
Later in the show they did an experiment with a full size obelisk at a granite mine in usa (first part was filmed in egypt) using first miniature prototypes and after a full size obelisk and a sand box(with dry sand vs. the damp one used in egypt).
Once the old-style(no modern machinery used here, except to set up the box and obelisk) ropes were gently released the obelisk practically pushed the sand away from underneath it and lowered itself into the right place. Final adjustement of about 15 degrees was performed by pulling the ropes.. Everything worked beautifully..

Hi!
Regardless of whether the amateur Egyptologists are correct or not, this is a significant piece of work for reasons only alluded to at the bottom of the DailyNews article: using kites affords low-tech (or no-tech) societies the means to achieve substantial power. They demonstrated substantial lift capacity in the Mojave Desert--but think about applying that lift to a lever, or using blocks (systems of pulleys) to lift, pry, or drag.
That's substantially more important than most /. readers might think. While we're living in a high-tech world that seems to only be getting that much more sophisticated, there are vast parts of the world that are still farming, building, and lifting with oxen. The Rodale Institute International Program [rodaleinstitute.org] has worked to get international food organizations away from a North American mindset that focuses on capital-intensive (and diesel-fuel-intensive) methods with big tractors and combines. Instead, they've applied a lot of what's been learned about farm implements to traditional means of propulsion (oxen). They're making a lot of headway--showing that a lot can be accomplished using low-tech methods.
This nice and neatly fits into the same scheme. Nobody's hoisting obelisks these days--but if you're building a road in Senegal, or upstream from the Three Gorges Dam, you may have a multi-ton rock to move. Instead of tackling the problem of finding earth movers big enough to solve your problem, you can drag it out of the way with kites. A vastly simpler, less expensive, more feasible solution.

Of course the thing under discussion in this example are obelisks, not the pyramids anyway. Obelisks were nowhere near the work to put up that the pyramids were. An obelisk is a single large block of stone that needed "only" to be lifted upright, rather than a huge pile of stones. Of course some obelisks were 100 feet or more tall, so this is not exactly a trivial task, but it's more a matter of tricky engineering than brute force labor like the pyramids.

Important point:
The pyramids were, in a real sense, not engineering marvels. They're just really huge stacks of rocks. There are a number of possible brute force approaches to getting the stones to the top that would be doable using even very simple technology. (Remember that the pyramid builders didn't even have wheels!) The pyramids are incredible more because they're huge and mobilizing the labor to build them was a tremendous political and administrative feat.
Obelisks, OTOH, are more of an engineering challenge. They're very large single stones (as much as 100+ feet tall) raised upright. It's getting them upright in one piece that's the tricky bit. They didn't require anything like the labor that the pyramids did, but how exactly they were raised up remains something of a mystery. There are a number of possible approaches, but all of them have problems, and in that sense they're much more interesting to modern engineers.

The sand and brick ramps were then removed, leaving no visible signs of how the obelisks got there.

It turns out archaeologists found sets of wooden arches with strapping. These 'arches' (don't know of a better way to describe them) would be strapped to the four sides of a block, on each end, thus making a square into a circle. (Think of drawing a circle around a square...The blocks ended up looking like a spool of thread, without the thread.) This solved the problems of resistance and provided an incredibly simple and elegant way for Egyptians to roll their blocks up the Pyramid ramps using significantly less manpower.

Even if mathematics was not at the forefront of slave minds, it is (and has been throughout human conquests) seemingly obvious to the minds of the repressed that sheer numbers and will can overcome a stronger foe.
So work the numbers a little. If the slaves were so weak compared to the Egyptians, they would hardly be capable of lifting obelisks. Ropes and pullys can only "scale" so far before throwing more bodies at the problem does not improve the chances of solving it. Space also allows a limited number of people to occupy it at once. Besides which, lifting stones builds muscle. Basically, the slaves were not weaklings.
If the slaves were so numerous, whether weak or strong, they would have an advantage of numbers over the Egyptians. Even with weapons, a limited number of Egyptians would be no match for an angry slave mob.

Stonehenge is a rather different problem to the pyramids.
For a start, the source of the stones used in Stonehenge is known, and it is from several hundred miles away (Southern Wales IIRC). This means that the biggest "wow" in the building of Stonehenge was the transport of the stones, and not erecting them.
Stonehenge is a group of discrete, freestanding stones, with the exception of the cross-pieces. Moving a stone into an upright position is a relatively simple exercise, even if it involves lots of gym. Upright timbers and ropes would have been more than sufficient, when combined with manpower, to lift the stones.
Placing the crosspieces, too, is more simple than the problems faced by the pyramids. For starters you only have to elevate the stone three meters. Given the amount of timber available in Britain (as opposed to the massive amount you will find lying all over in Egypt ...), it would not be difficult to build a strong enough scaffold. The Stonehenge crosspieces are also signifcantly smaller than the blocks used to build the pyramids.
It should be noted that Stonehenge is the largest and most well known of the ancient British monuments, but not the only one. There are several similar, but smaller, examples within a few miles of Stonehenge itself, and may others scattered around the countryside.
The pyramids were larger (on a massive scale), the stones used were larger (in general), and the structure consisted of many more than two layers of stone. In Egypt it is assumed the ramps were made of sand and mud, rather than timber, but significant amounts of timber would still be required as uprights either for scaffolding or simply to get leverage to raise (turn over, turn upright) blocks.

The conquered people could be marked (branded, tatooed) as a member of a slave caste who are then bought or sold for service. If the slave caste believes that it is their lot in life to serve, then they will serve (provided that they don't have a greater impetus to revolt).
If you believe all that biblical clap-trap about Joseph, he was sold to the Egyptians as a slave but he rose to a position of great power even though he was still a slave. Only a moron would give a leadership role to a person who they had abused (especially if they are made leader over others who you have abused).
Re:Modern Kites (Score:2)
Interesting. I recall having no problems flying traditional balsa wood and cloth kites when I was a kid 2-25 years ago. I've even built some kite-like devices of my (basically wings that generate life) from paper and wood today, though only small ones. In ancient Japan, kites were regularly built from light wood and paper. The Japanese have a very long tradition of flying kites.
Even with the best will in the world, I'm kind of curious how the Egyptians, with their technology, could have got a kite of that size to stay together in thirty mile an hour winds, let alone fly in any controlled fashion. And then have the strength to lift a several hundred ton obelisk?
I think that you are assuming that they used a kite in the traditional way, only they tied an obelish to it instead of holding onto the kite string to lift it up. This is not what the article proposed.
The technique that they mentioned involved building a tower next to the obelisk and attaching the kite to the obelisk via a rope that runs through network of pulleys in the tower. Then the kite is moved to the top of the tower where it can catch the wind and it takes off. The lift of the kite pulls the rope through the pulleys, which magnify the amount of force that the kite is exerting (which minimizes the size of the kite that is needed). They don't need to control where the kite goes. It doesn't matter which direction or how far off-center the kite goes as long as it is always pulling the rope through the pulleys to lift the obelisk. The only real problem is that if the wind dies down the obelisk may drop and shatter. I imagine that a few well-placed ratchets (of the type used in primitive trebuchets and catapults) would probably be helpful here.

I distinctly recall seeing a program where a crawler with a camera attached was sent up the shaft of the great pyramid and it turned out to be a dead end. I wonder if that was very recently done?

Getting closer. The three main pyramids at Giza line up (once you wind back the sky to the time that the pyramids were built) almost perfectly with the three main stars in "Orion's belt." This is not only in geographical alignment but also in relative size, i.e., the size of the pyramid is proportional to the relative brightness of its corresponding star.
Then there are seveal other pyramids that were built far away from Giza that also match up to stars in the constellation of Orion. According to the Egyptologists, what we refer to as the constellation of Orion was referred to by the Egyptians as the constellation of Osiris, the Egyptian deity that governed death and rebirth. Since the pyramids were tombs and the Egyptians believed that death was a transition to another world, it only made sense that if you were to build pyramids that lined up with any stars you would choose the ones that were related to Osiris.
Re:Occam's razor (Score:2)
I think that's a bit of an oversimplification of Occam's Razor. But what's more important is to remember that there were definitely engineers present. That is obvious from the math involved in the ratios of the pyramids sides and their alignment, etc. There really is a lot of complicated geometry and trigonometry in there. Take a look at the so-called "bent" pyramid, and you will see the learning process that the engineer went through once he determind that his original design wasn't done properly (or perhaps he predecessor's design).
At any rate, if engineers in ancient Egypt were anything at all like their modern brethren, then you can screw Occam's Razor. They would have done it the most efficient and clever way that they could devise, not by using the K.I.S.S. method. And then they would have bragged about it down at the pub afterwards.

I think that people overplay the lack of timber. Egypt was a large kingdom that traded with many other people in the Mediteranean. Lebanon was reknowned for their trees. Lebanon is not that far away from Egypt, especially if you wanted to ship overseas and then up the nile. For such an extravagant project, I can't imagine that they'd spare much expense.

You may find it interesting to note that there are some cultural similarities between ancient Egyptians and Ancient South Americans, not to mention that there is evidence of having been cocao plants, the source of choclate and cocaine, in ancient Egypt. Please note that these plants are indigenous to South America, not Africa. So there does appear to be some evidence to indicate that the Egyptians, or somebody that the Egyptians traded with, did in fact travel to and from South America.
Lack of proof means just that. LACK OF PROOF. That's the scientific method.
I almost agree with you, with one exception. The scientific method allows that what is currently accepted as truth or fact may in fact be incorrect. The scientific method is a method by which we can challenge accepted theory and hopefully prove new theories. It is not a method by which we can just sit back and say, "we already know everything about this topic and future postulation is therefore useless."
You're using the proof of one concept to demonstrate proof of another. It may be possible to demonstrate the building a kite-powered lifting scaffold - and THAT may prove it was possible, but it doesn't mean the Egyptians actually did it.
That's exactly what I've been saying. It doesn't prove that it *DID* happen, it merely proves that it was possible. Since we don't have any concrete evidence to the contrary nor do we have any concrete documentation as to how they were built, any reasonable speculation is perfectly acceptable. What I deem reasonable speculation is that which is a) proven to be technically feasible and b) that which isn't plainly proven by some sort of evidence to be untrue. The kite theory certainly fits that profile.
The absence of proof doesn't make an idea automatically crackpot. It's the continued pushing of that idea in spite of an absence of proof that makes it crackpot.
This is incorrect in principle and as it applies to this discussion. As it applies to this discussion, I am not "pushing" this theory. I am merely pointing out that it would be wrong to eliminate it from possibility just because it is unconventional. In principle, it's the wrong approach because it eliminates a lot of basic thinking that goes into research. When a scientist sees unexplained phenomena, he tries to make theories to explain the phenomena based on other knowledge that he has of similar situations. Then he tests his theories. If he waited until he had hard facts or evidence that explained the phenomena, there would be no such thing as theory. Theory is based on speculation, the same kind of speculation that the kite-flyers have offered here.
Actually, Cleopatra was a 7th generation incestual descendant of Ptolomy, a general of Alexander the Great's. She (probably) wasn't related to any of the people she ruled.
Good for her, but I think that it was obvious to anybody who read the post that I wasn't speaking in a strictly genetic since but in a cultural sense. Though she "probably" wasn't genetically Egyptian, she is considered by most to be Egyptian and for my purposes of comparing generations of Egyptians and Greeks made a good reference point. And since you're such the historian, shame on you for not knowing that the pyramid-builders were not contemporaries with Greek historians.

It's not. But why is it so hard to believe that they used their brains more than they used their muscles?
Beyond that, you make the same mistake as about 99% of the Slashdot posters here. You ASSume that they tied a rock to a kite, flew the kite, then skillfully positioned the kite to drop the rock where they wanted it. That's not what the article described. It only touched on the concept, but they built a tower where they wanted the obelisk. They ran a rope through the tower (via a network of pulleys) down to the obelisk. The kite was at the top of the tower (where there was more wind) and was presumably launched from there. With the kite tethered in this manner, you don't need to control where the kite goes so long as it keeps going up or in a direction away from the tower. This will pull the ropes, thus lifting the stone (or the obelisk). Stacking stones in this case is even simpler because the tower will allow the stones to be lifted to nearly the exact same location on the horizontal plane.
Why is it that nobody ever reads the articles anymore before shooting off their mouth? It plainly talks about pulleys and scaffolds.

It certainly doesn't appear to be all that unworkable, especially seeing as someone has already done it. If you'll recall, that was the point of the article.
Besides, just WHERE is it in the culture? If they actually used kites, where is the literature describing them? To the ancients, it would have seemed like the power of the gods (the wind) was helping them to raise their buildings. This theme would have been repeated in their literature and described by foreigners (ie Greek historians). There would have been wind and kite festivals (like in China). Little children of today would still be flying kites, like their ancestors. But none of this exists. There is NO ancient cultural tradition of kite flying in egypt - at least that I'm aware of. Show me EVIDENCE of such a tradition and I might believe it.
I'm not saying that the Egyptians built it this way. I merely pointing out that it is certainly quite feasible. You see an absence of concrete proof and automatically write it off as some crackpot idea that is impossible. I see a proof-of-concept experiment that demoinstrates the feasibility of an idea and think, "Hey, it's possible."
Just because there is no evidence that Egyptians flew kites 6000 years ago doesn't mean that they didn't fly kites. There are very large portions of the historical record that did not survive until the present day intact. If we did have all of the historical records, we would know for a fact how it was done. Remember that when we speak of the pyramid builders we aren't talking about a people who were contemporaries with Greek historians (or any other historians from whom we have writings). We are talking about a civilization that predates the Greeks by several thousand years. These are not the Egyptians of Cleopatra. They are the ancient ancestors of Cleopatra.

They don't have written records of how the pyramids were constructed. It makes more sense that they would have more personal records on the fact that they were enslaved. Most of the written records would have been created after they left and would have focused more on their experience rather than the technology of pyramid making.

This is an interesting view, but I think there's a bunch of people living in Israel (not to mention other parts of the world) that would strongly disagree. I'm pretty sure they have the written records to adequately describe their slavery at the time. Perhaps some of these pyramids and other items were erected after their departure from Egypt, but it's safe to say that slaves were used at some point during pyramid construction.

For a kite that size to sustain it's structural integrity under even light-moderate winds requires very strong materials in the wing itself (like nylon) and the assembly that shapes the kite (more than likely tubing from an aluminium alloy). The moments produced around assembled components would be surprisingly high, especially near the center if the wing.
Although the Egyptians were known for managing huge loads, it seems to me they wouldn't have anything strong or light enough to support these kinds of forces. (My point being, if they did construct a wing, the freakin' Kite would most likely weigh several hundred pounds itself)
