Carbon nanotubes

Carbon nanotubes are long chains of carbon held together by the strongest bond in all chemistry, the sacred sp2 bond, even stronger than the sp3 bonds that hold together diamond. Carbon nanotubes have numerous remarkable physical properties, including ballistic electron transport (making them ideal for electronics) and so much tensile strength that they are the only substance that could be used to build a space elevator. The specific strength of carbon nanotubes is 48,000 kN·m/kg, the best of known materials, compared to high-carbon steel’s 154 kN·/kg. That’s 300 times stronger than steel. You could build towers hundreds of kilometers high with it.

Metamaterials

“Metamaterial” refers to any material that gains its properties from structure rather than composition. Metamaterials have been used to create microwave invisibility cloaks, 2D invisibility cloaks, and materials with other unusual optical properties. Mother-of-pearl gets its rainbow color from metamaterials of biological origin. Some metamaterials have a negative refractive index, an optical property that may be used to create “Superlenses” which resolve features smaller than the wavelength of light used to image them! This technology is called subwavelength imaging. Metamaterials would be used in phased array optics, a technology that could render perfect holograms on a 2D display. These holograms would be so perfect that you could be standing 6 inches from the screen, looking into the “distance” with binoculars, and not even notice it’s a hologram.

Bulk diamond

We’re starting to lay down thick layers of diamond in CVD machines, hinting towards a future of bulk diamond machinery. Diamond is an ideal construction material — it’s immensely strong, light, made out of the widely available element carbon, nearly complete thermal conductivity, and has among the highest melting and boiling points of all materials. By introducing trace impurities, you can make a diamond practically any color you want. Imagine a jet, with hundreds of thousands of moving parts made of fine-tuned diamond machinery. Such a craft would be more powerful than today’s best fighter planes in the way an F-22 is better than the Red Baron’s Fokker Dr.1.

Bulk fullerenes

Diamonds may be strong, but aggregated diamond nanorods (what I call amorphous fullerene) are stronger. Amorphous fullerene has a isothermal bulk modulus of 491 gigapascals (GPa), compared to diamond’s 442 GPa. As we see in the image, the nanoscale structure of the fullerene gives it a beautiful iridescent appearance. Fullerenes can be made substantially stronger than diamond, but for greater energy cost. After a “Diamond Age” we may eventually transition to a “Fullerene Age” as our technology gets even more sophisticated.

Amorphous metal

Amorphous metals, also called metallic glasses, consist of metal with a disordered atomic structure. They can be twice as strong as steel. Because of their disordered structure, they can disperse impact energy more effectively than a metal crystal, which has points of weakness. Amorphous metals are made by quickly cooling molten metal before it has a chance to align itself in a crystal pattern. Amorphous metals may be the military’s next generation of armor, before they adopt diamondoid armor in mid-century. On the green side of things, amorphous metals have electronic properties that improve the efficiency of power grids by as much as 40%, saving us thousands of tons of fossil fuel emissions. 

Superalloys

A superalloy is a generic term for a metal that can operate at very high temperatures, up to about 2000 °F (1100 °C). They are popular for use in the superhot turbine areas of jet engines. They are used for more advanced oxygen-breathing designs, such as the ramjet and scramjet. When we’re flying through the sky in hypersonic craft, we’ll have superalloys to thank for it.

Metal foam

Metal foam is what you get when you add a foaming agent, powdered titanium hydride, to molten aluminum, then let it cool. The result is a very strong substance that is relatively light, with 75–95% empty space. Because of its favorable strength-to-weight ratio, metal foams have been proposed as a construction material for space colonies. Some metal forms are so light that they float on water, which would make them excellent for building floating cities, like those analyzed by Marshall T. Savage in one of my favorite books, The Millennial Project.
