What if we turn CO2 into fuel or explosives?



"Researchers in Japan developed a fast, efficient method to convert CO₂ into carbon monoxide using a low-cost catalyst, cutting processing time from 24 hours to just 15 minutes. Their spray-based technique not only meets industrial standards but also outperforms all previous similar catalysts, offering a major step forward in sustainable fuel production."(CoPc) crystals.

Turning CO2 into fuel is one of the most interesting things that can slow the greenhouse effect. The system must only separate carbon from oxygen. And then keep those atoms close enough that they can burn. The problem has been how to make that in real life. There is the possibility to make "explosive diamonds" by using some new technologies. 

There is the possibility. That the next-generation aerial vehicles use carbon as fuel. In those systems, carbon can be packed into the nano-size particles. Those particles can be smaller than the smoke. The engine conducts that nano-smoke into the combustion chamber.

Then the system injects pure oxygen into them. 

The system must only make the carbon crystal there are oxygen atoms between carbon atoms. That kind of thing can give a very high-power explosion. There is a test using carbon-oxygen chains to create new types of very effective explosives that can beat even the RDX. The problem is that the new explosives don't need even nitrogen to catalyze the reaction.

In those explosives, the reaction where carbon joins oxygen happens in so large area. Where the explosion is powerful. We can think possibility of making a molecule like graphene. But in that molecule, every carbon is connected with oxygen. 

If oxygen joins carbon at the same time over the entire layer. That gives a powerful explosion. The number of carbon and oxygen atoms that participate in chemical reactions at the same time determines the burning speed and power of the explosions. 

And that makes them slip through explosive detectors. 

Carbon-oxygen chains can also make it possible to create new types of rocket fuels. That rocket fuel fits into new nanotechnical aerial vehicles. Nanotechnology can make carbon-oxygen ladder molecules that the system drives to the combustion chamber. The system can keep that explosive in roll there the engine feeds it into the engine chamber.

Atomic spray can revolutionize material research.

Atomic spray can make the next-generation 2D surfaces possible. The atom spay can deliver a single-atom layer over the surface. 

It can revolutionize things like microchips and armor technology. The atom spay can drive a single atom layer of copper to the layer. 

That makes it possible to create very thin electric wires. Those systems can used to create new economical microchips that create low temperatures. 

Resistance is one of the biggest problems with microchips. All electricity that the microchip pumps into the IR radiation wastes electricity. 


And that is one of the reasons why energy efficiency in high-power data centers is important. 


Heat causes resistance and oscillation in wires. That disturbs the data flow. Energy efficiency also makes electric bills lower. AI requires lots of electricity. And that's why the electric efficiency is important. That's why data centers should have systems that turn IR radiation into electricity. 

Or those systems are under development all around the world. Same way. Data centers require their own independent power sources like micro nuclear reactors or geothermal systems. 


The atomic spray makes it possible to create the next-generation large-size graphene surface. 


The thing that makes graphene the ultimate material is that it has only one atom layer. The thing that makes normal carbon structures fragile is that their carbon structures are not ordered. 

The overlapping atom structures allow the upper layer in regular carbon to penetrate between lower layer structures. 

Even if. The carbon structure in graphite is in lines. The impact forms standing waves to the carbon tubes. That destroys the material. There is only one carbon atom layer in graphene. And that denies lots of resonance between it and the lower surface. 

That is separated from other carbon layers. So. When something hits graphene. It conducts impact energy horizontally. That makes a graphene tool that can cut even diamonds. The graphene oscillator can send acoustic waves to the diamond structure and make diamond atoms oscillate. That can break the diamond. 

The atomic spray can turn the next-generation armor possible. The idea in those 2D atomic layers is that those layers are connected using nano-springs or DNA bites. Those multi-layer 2D graphene structures can bind the impact energy of ammunition. The lightweight armor is suitable for things like satellites. Graphene itself binds impact energy efficiently. The reason for that is when projectile impacts to graphene the 2D carbon layer conducts energy into larger areas. 

The reason for that is this. Graphene cannot conduct energy to the lower surface. And that makes it so hard. Graphene cannot cause resonation in other than carbon atoms. And that means it conducts energy horizontally. 

The multi-layer graphene can be an ultimate tool for IR stealth technology. The multi-layer graphene means that the graphene layers are separated from each other using some other materials. The layers are like pillars that are between them. 

If the aircraft lets ram-air travel between graphene layers. Or aims the laser rays through those holes between carbon atoms. That conducts energy out of the structure. The problem with graphene is that it's quite hard to cover large surfaces using this kind of material.
