Self-assembling 3D Nanostructures

Roland Piquepaille writes "Chips holding 10 terabits of data? Copper as strong as steel? Ceramics tough enough to be used in car engines? All this will be true in five years, thanks to two new methods to create self-assembling 3D nanostructures. These methods used pulsed laser deposition to create layers of nanodots organized in a matrix. These arrays of nanodots are consistent in shape and size -- 7 nanometers with nickel for example. But the real beauty of these methods is that they can be applied to almost any material, like nickel for data storage or aluminum oxide for ceramics. These methods also reduce drastically imperfections, leading to future superstrong materials. Read more here for other details and an image of a single nickel nanocrystal, or nanodot."

      Also, if you can arrange things properly you might get it so that air friction acted to speed up the rotation of the arms...but I'm not sure what effect that would have on delta-V at contact, which you would prefer to be zero.

      Additionally note that with a pinwheel, you never visit the pinwheel, so the cargo is aimed at it's destination by timing when it releases from the arm. So you'll want at least minor manuvering capability internal to the pod. (I.e., small rockets, probably.) But these won't be needed until you are in the vicinity of your destination.

      Also notice that as with most skyhooks, the system isn't stable in the long term unless you download as much mass as you upload. So collecting meteors becomes essential. (You sure aren't going to collect your escaped rocket propellant.) Things would be easier if there were a catapult on the moon that could launch chunks of rock for downloading to earth. That might be cheaper than catching meteors...and the darkside of the moon is a the best place for an observatory anyway. (Probably a totally automated one, though, so forget every SF story about such a thing.)

      The scaled composites page is quite interesting, and may apply to the kind of thing that would BE the cargo pod, but you want to be able to lift pods in the multi-ton range, and preferably above the kilo-ton range ... well, that may be dreaming excessively, and the heavier the thing you can lift, the higher the central mass needs to be, not to mention the stronger the cable, so start with something that can manage a loaded Apollo capsule.

If you could imagine a geodesic polyhedron 2 miles in radius with steel pipes 2-3 metres in radius for the edges, the force exerted by raising the air temperature inside the pipes by just a couple of degrees would be enough to make the structure float in the air.

      The closest real-world implementation at present is a nyoln fibre airship, with helium gas for lift. Roughly, you get 1 Kg of lift for every cubic metre of Helium. For a 6x2 metre airship with 25 cubic metres, the weight of the skin is around 8 Kg, when inflated, and 25kg of lifting weight.

      In a perfect structure without faults, one layer would be enough (think buckyballs), but the diamond-lattice wouldn't be stable at all that way.

      Even then if you would make structures where the mass / volume would be lower than the density of air it would be difficult to get it to float in the air. Just try it, if you make a hollow object, and try to scale it up, the surface will scale with the power of two, while the volume will scale with the power of three. So, at large enough scales any vacuum hollow object can have a mass/volume lower than the density of air. If this would work, this would be a cheap and safe way to build zeppelins ;) I guess it really only works for objects which are in the gas phase at air temperature, and diamond doesn't really fall in that category.
