The all-carbon Katana

This idea is just sci-fi, for now, and relates to my sci-fi book.

Even with all the available fancy guns available to them, modern sci-fi heroes often use swords. Gi Joe, Blade, The Matrix, Riddick, Star Wars are just a few that spring immediately to mind.

Often they use Katanas or Ninja swords because they look good.

In my last post I mentioned cubic carbon. I originally introduced the concept in my main blog at:

Cubic carbon would be very hard, it can be made at all. It could hold an incredibly sharp edge. The blade of a Katana is usually made of folded carbon steel, but  with carbon fibre and graphene string to make and wrap the handle and guards, composites of carbon nanotubes, graphene and cubic carbon for the blade, and a cubic carbon edge, with maybe a few diamonds and graphite patterning to decorate Carbon Girl’s Katana, a pure carbon Katana could be made for both her and Carbon Man. No other materials are needed at all. 

Perfect. But if they aren’t allowed to take them with them for some reason, they can quickly fabricate temporary but lethal substitute using nothing more than carbon tape.


Disk and dart weapons

I have a toy gun that fires spinning foam disks. It is pretty harmless of course. But it gave me an idea for the armory. Swords are fine for close up engagements, but a gun is hard to beat at a distance.

A graphene disk would be ideal for high-speed projection. The material of the disk would support high electric currents and therefore magnetic field interaction with the gun. Without bothering with too much detail, a future professional version of a disk gun could be made that fires ultra-thin (sharp) but highly strong graphene disks, spinning at high speed, and having minimal air resistance.

So the disks would shoot quite far, and self stabilising so fairly accurate, and very sharp, so would do damage. A high-speed cluster of them could be used to good effect to significantly damage or impede an enemy.

Electromagnetic forces could also be used to fire graphene darts. No new concepts are needed, the rail gun already exists and that mechanism would be perfect at any scale. Darts would scale too. Small darts with just a few layers of graphene would be very lightweight so convey limited mechanical damage, even if travelling fast, so they may be best suited for puncturing and short circuiting electrical equipment. Thicker and heavier ones would be much more lethal, adding mass and strength using any carbon material in the center, and being very streamlined and sharp if they taper the number of layers at the edges.

Cubic carbon is a fanciful material that may not even be possible to fabricate, using all 6 electrons to form bonds with neighbors in a cubic structure. It should be extremely hard, and such a material would be useful to make or add tips or edges to projectiles that could pierce or damage anything.

Carbon tape weapons

There is no shortage of traditional weapons, such as bows and arrows, swords, spears and an endless variety of guns, lasers etc. When none of these are permitted, you could fabricate and entire armory with nothing more than a roll of graphene tape.

Once graphene is easily producible, it will be possible to buy graphene tape. When I was a child, my friends and I used to make swords by rolling up tape measures and pushing the center through and drawing it out as far as possible to a point. If you roll up graphene tape and draw the center out, the point could be pretty sharp. Being graphene, it could also make a pretty strong rapier.

Also by winding some layers around a triangular cross section cardboard tube (or carbon fiber, or even a piece of scrap paper), a pretty rigid tube would result. Bending and tying the ends with strong graphene string or tape would result in a bow or sword.

Graphene weapons

Graphene weapons

The stringed bow would only need very fine string thanks to the huge strength of graphene. This would make a good bow but also make a cutting weapon in it own right. If a layer of tape instead of string were used, the same strength would be available with an even sharper edge.

Carbon Girl’s stilettoes

Our athletic, stylish and elegant, but nevertheless highly formidable Carbon Girl wears some pretty mean shoes. The heels make very potent weapons. The heel has to work on normal ground, so it uses a concertina design using carbon muscles to allow a broad base to be extended for softer ground, making sure she doesn’t sink into soft grass at weddings. However, with a single thought and emotion recognition based command, the broad heel is drawn upwards, revealing a solid cubic-carbon stiletto coming to a single carbon atom point, with an edge extending all the way up the reverse of the heel, far sharper than possible with any other material. Able to cut through anything, the tip can even penetrate the diamond helmet worn by her nemesis.

The bulk of the shoe is made of carbon fibre. Intricate but electronically changeable patterns in the upper layers enable a wide variety of appearances to be achieved, able to be switched into a computer display at will. The heel height is entirely variable, as is the profile. Carbon Girl only needs one pair, but she still has lots.

The Carbon Trio’s Base (The Car-Base?)

Everyone needs a home, even the military and superheroes. I describe the basics of how the super-tall structure on which the Carbon Trio’s home is built here:

Future posts on that sister blog will outline some of the rooms, materials and devices in it. From a military point of view though, probably the most useful aspect is the ability to place it on top of a structure 30km tall, and theoretically even 600km tall using the latest strength figures for graphene. Some of what follows will just be place-markers for future posts.

From such high altitudes, surveillance capability would be very high. So would the ability to use it to launch gliding vehicles and to house directed energy weapons, and obviously make it easier to attack space-based targets or launch other weaponry and equipment into space. It would therefore be a valuable target for opposing forces and would need protection. Assuming that the military of at least one country have adopted the Carbon Trio as citizens or allies, it is reasonable to assume that the platform would therefore be permitted to house defense-related systems.

Lasers are an obvious choice for long-range attack on incoming missiles or planes. Graphene has already been noted for its excellent properties in making lasers, so graphene lasers would certainly be a top priority. Electron pipes would be useful too. Electron pipes are basically linear accelerators that could fire high energy particle beams. I invented them originally as a high-speed upgrade to optical fibre. The original invention dates back to 1991 and is available here: As a telecomms system, it offers high bandwidth and could certainly be used for high speed comms around the platform to link the high bandwidth devices together. As a weapon system, the Carbon Trio would need to increase the length of the pipes by looping them around their base, increase the voltage by a few zeros, and thus produce a high energy particle beam. The pipes could be nanotubes or graphene tubes, and the coils use graphene wire. A large number of them could be used in parallel to make an intense beam. With the power supply sufficient (I’ll discuss some power generation potential in a later post).

The Car-Base would also be able to use mirrors to deflect solar energy. For weapon use, this would mostly come from a space-based array of mirrors. The maximum power level would mainly be limited by international treaties. The sun certainly provides intense enough power to make useful redirection weapons feasible.

Graphene dart swarms could also be released from a high altitude platform. These would be very thin and sharp, so could accumulate very high velocity before homing in on their target. These can wipe out an entire force of soldiers, easily penetrating standard issue protective helmets or a vehicle roof. Again, a future post will give more detail.

The defence of the Car-Base would not depend solely on weapons. It would also have formidable defences. The structural materials would be extremely strong – carbon fibre would probably be the weakest of them and even that is a good starting point. Graphene, carbon chainmail, nanotubes, carbon foam, cubic carbon and diamond are all pure carbon with very high specs, although a few are still expensive to make, future technology will bring costs down a great deal.

The combination of these materials offers a wide range of excellent electrical properties too. Using variable electric and magnetic fields as well as the principles of self organisation, evolution and self assembly, elaborate self healing structures could be assembled and maintained. They could be ruptured in a powerful attack, but could quickly self repair. Some structural components might provide small areas of force fields that could provide some protection but allow ultra-high speed opening and closing of gateways.

And of course, the final line of defense would be a squad of combat drones, under Carbo’s command, naturally.
