New graphene bricks can be the next version of graphene.

Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. (Wikipedia/Graphene)

Graphene is the ultimate material. It's a single-atom layer of carbon, and that structure makes it impressive. The graphene can be fixed if there is a hole by putting the repairing piece in that hole. And then the covalent bonds connect that repairing piece in the atom layer. That kind of ability makes graphene one of the most fundamental materials in the world.

"Graphene is an atomic-scale hexagonal lattice made of carbon atoms." (Wikipedia/Graphene)

But how to make 3D graphene without destroying the attributes of the 2D carbon material? The answer would be easy. Four graphene bites can be put in cubes. And then those cubes can be put in the right places like bricks. The graphene bricks are the empty cubes that are made by using four 2D graphene layers. 

That 3D cube structure makes graphene easier to handle. And that thing can make the next revolution in materials that are more impressive than ever before. The graphene layers can make the material more durable than ever before. But the problem is that graphene is quite hard to handle. And if we would cover aircraft by using graphene. That thing requires lots of graphenes. 

Graphene loses its abilities if the single atom layer cannot stabilize. The graphene layer requires the ability to make the single-atom layer. Or another version is to use graphene bricks or graphene boxes. 

Graphene can be the material of the most modern stealth technology. In that kind of system, particles like electrons will trap in the cell of this material. Then the system stresses that particle with electromagnetic radiation. The idea is that this system makes the counter waves against radars by using this kind of structure.

The "space helicopters" or MHD-driven aerial vehicles can revolutionize aviation.

Engineers can install the MHD (Magnetohydrodynamic Drive) engine system in lighter-than-air vehicles. That allows them to operate also in the atmosphere. Normally, MHD cannot rise heavier-than air crafts from the ground. But that system could work with high-altitude airships. If those craft's body is made by using modern carbon fiber-based materials they could fly to space.  Researchers can use these kinds of systems in the HAVOC (High Altitude Venus Operational Concept) mission to Venus's atmosphere. Or at Earth's atmosphere. 

The ion engines are one of the most promising systems for interplanetary missions. But ion engines, or electric jet engines can also use in aircraft. Those engines are ionizing air in front of them, and then the magnetic accelerators will accelerate those ions to the back of the system. This kind of ion system could make the aircraft very highly maneuverable. Advanced ion systems are powerful tools. They can form ion whirls that crush all meteorites or ammunition that are closing spacecraft or aircraft. 

Originally engineers planned to install this ion propulsion system in plate-looking submarines. The ion system just ionizes water. And then, drives it in the wanted direction. This type of MHD (MagnetoHydrodynamicDrive) aims at the direction of the ion flow by inclining the plates. In some models, the MHD drive would install in airships. That thing makes it also suitable in atmospheric flight even if it cannot lift heavier than air crafts upward. 

There are also introduced models where the system uses the electric arc or rocket engine that creates pressure between plates. The system would incline the plates that allow it to control the direction of the jet. Those systems can use two plates that are acting like Kamov-type rotors. The overpressure system could quite easily install in the same structure with MHD/MDD (Magnetodynamicdrive). 

The plate-looking aerial vehicle which uses ion engines can be the source of UFO sightingsThe electric system will ionize the air in the front or middle of that structure, and then the system will incline to the plates. The system would use radially installed magnetic tracks that aim the ion flow into the wanted direction. That kind of system can make the craft able to make a very strong maneuver. 

Some futurologists made a theoretical model of the interstellar or interplanetary spacecraft that uses black holes or electromagnetic, virtual black holes for operating in space. The system makes the plasma disk around the craft using high-power magnets. Then they would shoot the plasma pikes in the disk and that causes asymmetry which pushes the craft forward. The problem with those systems is the power source. 

That ion whirl also can form the Tipler-cylinder around the nuclear-powered spacecraft. This type of system could also use small-size black holes for making the plasma disk. But basically, those kinds of systems require only high-power magnetic fields. Another thing that this ion whirl can make is aim the radar signals away from the structure of the craft. The ion whirl can also form the ion-based power field around the craft, and those ions will destroy all incoming material targets.
