Carbon foam balloon as military platform

In my sci-fi book, the Carballoon is a huge carbon balloon made mainly from graphene foam. (In a nutshell, graphene foam is made up of tiny graphene spheres with a vacuum inside to give an average density lower than helium.)

It has many civilian uses as described there, but is also useful militarily. 

Some of the smaller balloons that it can send out would have reconnaissance or espionage functions. Some would have weapon systems on board, and having variable buoyancy, could sneak into an area at high altitude unnoticed before descending and bringing death from above. They could occupy some of the roles occupied by today’s drones, so would likely be covered by similar legislation.

Subject to that legislation, weaponry could include guns, directed energy or particle beam weapons, and graphene dart swarms, as well as missiles and bombs. These weapons would potentially scale with balloon size so that the mothership Car-Balloon would be very powerful.

The main advantage balloons convey is range and duration. They could stay afloat permanently without consuming power. They could sit stealthily for long periods on standby before being woken up to come into action. In fact, all the time they are afloat, the solar cells on the upper sections could accumulate energy and store it in graphene super-capacitors, to be released as required.

Graphene foam would be a very low density solid, so it would not fall if punctured. The pieces would stay afloat even if it were broken up. Self-organisation and assembly functionality could be distributed throughout the foam to allow pieces to come back together, and thus enable continuous self-repair.


Carbon foam – lighter than helium, stronger than steel, perfect for padded bra armor

A Carbon wardrobe could hold a huge variety of garments and styles, just like yours. Not all wardrobes include padded bras, but for those that do:

Even using lots of connected layers, the carbon chain-mail protection layers of carbon armor would still be pretty thin and highly transparent. They would block and deflect damage from swords and knives, but another layer of hard but flexible carbon foam between layers of clothes would help to absorb energy from bullets too. Any areas where damage does occur can be swiftly repaired using a variety of self healing mechanisms.

For potential superheroes who feel they need a bit of extra padding up top, carbon foam feels comfortable, keeps the body cool, adds extra protection, and adds curves. It is lighter than helium, so it also gives a bit of extra lift.

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.
