To begin with, I thought of a Buckyball design that could make an awesomely strong self-assembling frame work for a death star sized space station. Now because the plan requires the frame to be as internally stable as the external frame work I would need a design that offers the best of both worlds.


hyperdodecahedron

Animated


 Wink At 120 dodecahedra, with 3 to an edge, and 720 pentagons. The 120-cell has 600 vertices and 1200 edges. It is one of the six regular polychora. One can only guess at the structural strength.


The dual of 120 cells is a 600 cell design:
Animated


 It is composed of 600 tetrahedra, with 5 to an edge. The 600-cell has 120 vertices and 720 edges.

Note the natural spherical shape that this geometry creates.

Now, I would like to invite any structural engineer to explore this design.

You HAVE been busy haven't you?
Have you got transport tubes in that thing?  I sure wouldn't want to have to walk to work every day!!

Imagine a Star Trek movie with a Borg Hyperdodecahedron.

I did actually, and alot of this idea is very Borg like.
In fact it's almost a mixture of star wars and star trek sciences and theories being acheived to the best of our abilities or that we do know of.

Hyperdodecahedron appears to be the most stable structure to support the sheer size of the thing under it's our gravity. I still want a structural engineer to examine weight distrubutions and overall design.
Volitzer- are you aquainted with space shuttle dynamics? I am studying possible designs for shuttles launched from an electro-magnetic rail-guns.

Summary: Development of Maglev (magnetic levitation), a new mode of transport in which high speed vehicles are magnetically levitated and propelled along a guideway, began in 1966 with the invention of superconducting Maglev by Powell and Danby. Since there is no mechanical contact or friction, the speed of Maglev vehicles is only limited by air drag. In the atmosphere, the practical limit is about 500 kilometers per hour (/spl sim/300 mph). In low pressure (e.g., 1 torr or less) tubes or tunnels, speed is only limited by the straightness of the route, and the distance between stations, with the need to accelerate and decelerate. Tunnels are generally too expensive, 30 million dollars per mile or more, to be practical for most Maglev routes. However, undersea tubes have the potential to be lower in cost, and can provide intercontinental travel at speeds of thousands of miles per hour.

Any design concepts in mind?
 Smiley

I have a particular location that can provide hydro-electric power and it's almost right on the equator.
Because the first launches will be sending the fully automated systems, no human launches will have to be done right of way. If our material can be packed into these transformable shuttle systems to handle alot of G-forces, we can launch those things one right after the other at any speed they can handle.

The shttles would have to be made of the same little robots that they will be carrying into space.
This is the challenge. First these units will have to assemble into launchable units. Then enter orbit, transform into the next portion of assembly. Then selfsustain itself using collective systems and comunication with command satellites that will eventually become a part of the structure as well.

Actually yes. Mag-lev trains with transport tubes attached to the structual supports and other internal frame tress structures.
Instead of the train riding on a rail from underneith, it will be suspended from overhead and on the sides.
Triple-rail. Train design is arrow-shaped to reduce drag.
How fast will it be?
Because there is no mechanical contact between the Maglev vehicles and its guideway, friction and wear do not impose any limit on the speed of the vehicle. A few short minutes and your at a location clear on the other side of the station. Mass transit systems are only one of the ideas. Personal transit might also be discussed in the near future.

If this can be acheived: 


The structure would be 12 times higher than the Great Pyramid at Giza, and would house 750,000 people. If built, it will be the largest man-made structure on Earth. The structure would be 2,004 meters (6,575 feet) high.
By creating:


We can go for something that is atleast 10 times the size of this and you would end up with:

 Smiley  What a metalic model of this design produces is:


As we begin the adventure through this maze of structural components, notice the way every cross member seems to interact with every other member in it's pod.

Orthographic Veiw

Construction phases


1. Start with a single dodecahedron.


2. Now add one dodecahedron on each face of the first dodecahedron. First add one in the back, and five around that.

3. Now we have seven. (one is directly in back and not visible)


4. Add five more, and finally a twelfth right in front.


5. Now we have one central dodecahedron with twelve around it, for a total of thirteen dodecahedra. Notice that there are now twenty little indentations or dimples, one corresponding to each vertex of the original red dodecahedron. Only five are really visible, but if you compare their location to the original dodecahedron, you can see that they are in the same location.


6. We now add one dodecahedron in each of the twenty dimples. In this step we add ten (five of which are in the rear and not visible)


7. Now we have twenty three.


8. Now add five more.


9. Now we have twenty eight


10. Finally, add the last five.

11. Now there are thirty-three (1 + 12 +20) dodecahedrons. Notice that there are now twelve dimples, corresponding to each of the faces of the original dodecahedron. (look at the green faces).


12. Now we add dodecahedra in each of these spaces. First add one directly in back, then five around it (all not visible here), then five more, that you see here, and finally a last one right in front.


13. Now we have 45 ( 1 + 12 + 20 + 12 ) dodecahedra. Again, we look for dimples. They are hard to see because the shapes are beginning to get stretched and flattened. They are where two of the yellow dodecahedra come together. Again, they also correspond to parts of the original dodecahedra- this time, the edges. Ten of them are visible, but only five here look like dimples.

And done with a fully autonomous system.......

Touching base on transportation aboard our station, we discussed mag-lev systems.
A maglev, or magnetically levitating train is a form of transportation that suspends, guides and propels vehicles (predominantly trains) using electromagnetic force. This method has the potential to be fast and quiet when compared to wheeled mass transit systems, potentially reaching velocities comparable to turboprop and jet aircraft (900 km/h, 600 mph). The highest recorded speed of a maglev train is (361 mph), achieved in Japan in 2003, 6 km/h higher than the conventional TGV speed record.

More personalized transportation is already in the proposal stage for mag-lev transportation.


This SkyTran system operates with individual, two-passenger vehicles, which are propelled and suspended by a maglev system from overhead guideways.

Looks like it would be a total blast. This pod is probably made with a super light weight material and the speed would be incredible. The G-forces would play a role on how fast it would be and what that individual could handle. Then a final set speed for everyone would have to be figured out to avoid things like catastrophic collisions and road rage. However computer controlled motion and monitoring system would be in place to prevent collisions at a merge points in travel.
