Superconductivity and collapsible power plant satellites can be the systems that can slow climate change.




Image 1) "Experimental data from trilayer graphene (bottom) shows two circular Fermi surfaces, creating a ring-like shape, in which the occupied electronic states lie (top). In unconventional superconductivity, the electrons are assumed to be “glued” together by interaction, not to be confused with their usual interaction of electrical repulsion. (Courtesy: IST Austria)" (Physicsworld/New explanation emerges for robust superconductivity in three-layer graphene). 

In that image, you can see that the outer electron is traveling the outer layer in the quantum field. And the inner electron is traveling near the structure. So the energy travels between those electrons from the outer quantum field to the inner quantum field. The idea is that the size of the outer quantum field is larger and its energy level is higher than the inner quantum field if the inner quantum field is lower energetic. 

When electrons prowl the outer quantum field it travels a longer journey than the electron, which travels in the inner quantum field. More energy is transmitted in it than to electron that travels in the inner quantum field. So the structure inside the inner quantum field can turn lower energy by cooling it with the Bose-Einstein condensate. 

The superconductivity with three-layer graphene can be more fascinating than we ever imagine. The reason for that phenomenon could be that the up and below the middle graphene layer would make the pressure effect that denies the oscillation of the middle layer. 

The resistance is extremely low in 2D materials. Because the wires are so thin, oscillation in that kind of material has no similar effect with the oscillation in regular wires. That thing makes that three-layer graphene structure superconducting. The superconducting materials are interesting. 

They can use in quantum computers but those superconducting materials are suitable to use in the systems that are synthesizing energy from the radio waves. The superconductivity can be very interesting if that thing is connected with Lorentz Butterfly. The Lorentz butterfly would be the superconducting antenna, that pumps energy to the system. The idea of that thing is that the energy level will rise in the system until it can transfer somewhere. 

The 2D graphene and the systems that can transform radio waves can use as an energy source in long-term space missions. Those systems don't need nuclear fuel. But the problem is how high voltage those systems might have the ability to create.

Collapsible power plant satellites can be in use sooner than we expect. 


The thing is that the kilometer-size structure that is launched in one shot for testing the artificial gravitation can work as a pioneer for creating large-size space structures. Artificial gravitation doesn't mean that its strength is the same as the gravitation on Earth. The purpose of gravitation is to anchor objects to their positions. And the benefit of artificial gravitation is that it anchors also non-magnetic objects like flowerpots to layer. 

The kilometer-size space structure can also be the pioneer for power plant satellite structures. The idea is that the large-size solar panels can be like small scaly silicon cells that are on the large mylar layer. That structure can make the power-plant satellites possible. 

The mylar structure can connect to the power delivery unit. And the system can transmit energy to Earth by using lasers or radio masers. The energy transmission would happen by targeting that radiation to antennas. That kind of system is more flexible than the systems that are planned in the 1970s. The power plant satellites are introduced for the choice for use of fossil fuel. And maybe they are real sooner than we expect. 

Some people resist that technology. Because those satellites can also use as killer satellites. And they can create megawatt-scale electromagnetic radiation that can affect ICBM swarms and those systems can also be dangerous for cities. Even if that satellite cannot destroy the houses or melt stone on the ground. It can form powerful EMP-pulses.

The new materials are pathfinders in photonic circuits and stealth technology.



The new graphene-based material reflects light backward. And it is a big step for the next-generation photonic circuits. But the new nano-materials are also possible to use in the next-generation stealth technology. There is introduced an idea to conduct the radar impulses to the accumulator. That means that the radiation's reflection is denied by conducting that radiation to energy storage. 

The thing is that if the energy and wave movement travels only to the object without reflection. There is no way to see that object. But the problem is that the system must sometimes remove the extra energy by conducting it to the ground. 

And there are suspicions. That some UFO:s that are hovering above the water is removing their energy storage. In that case, those aviation systems use technology that absorbs all radiation in the craft. So when the energy level rises too high the craft must remove extra energy to somewhere. 

Graphene-based materials have an abnormally strong absorption ability. The problem is that if the object would not reflect. It will turn very hot if it cannot remove that heat somewhere. The new graphene based-material allows conducting the light to the point where the researchers want. And that ability is useful in photon circuits. But it can also turn the aircraft or ship into shadow. The light can conduct to a laser that sends it in the wanted direction.

And the problem with this type of material is that they must remove their energy somewhere. The overload of energy causes the problem. The answer to that problem could be to load the extra energy to capacitors or the energy can conduct to air by using saltwater where the extra energy is loaded. 

And that thing can make it possible to make the objects that are not giving a reflection at all. There is the possibility that the graphene-based materials are conducting light and all other electromagnetic wave movements to the middle of the object like aircraft. And then that light and wave movement can conduct in the wanted direction by using laser technology. 

One version of how to deny reflection is simple. The system must just make the object that has as low an energy level as possible. That thing makes it possible that the energy travels only to the object. And that makes the object invisible for radar, infrared, and even for the human eye.

The bulletproof clothes might be true somewhere in the distant future.

The graphene might be very advanced material alone, but connecting those graphite layers together with another material gives graphene more advanced affection. I'm writing here about the material, what consists graphene with two layers, and in the middle of those layers could be the titanium structure, what works like spring.


Material works like that the outer structure will take the punch, and between those layers is so-called nano-springs, what will suck the power of the punch, before it will conduct to the downed layer of the graphene. That might give the graphene even more capacity, than what it has now. When we are talking about graphene as the material of the bulletproof vests and clothes, we must create some kind of different material that graphene.

2D graphite network would give awesome capacities for the solid surfaces, and if the graphene can put in some particular profile, that can be used as the cover the surfaces of the fighter like F-16. The double surface nano-spring graphene could give more heat and punch tolerance for those aircraft and of course, that material can be used at any surface in the world. When the bulletproof material is in the multi-layer structure, it will be more effective stopper than single layer material.


If there will be little room, what separates the surfaces that will five very good isolation against heat. This kind of information is taken by the spacecraft, what needs protection against micrometeorites. But when we would want to make the bulletproof clothes, we might want to have the material, what feels soft like normal canvas, but could stop the bullets. That kind of material seems very difficult to make, but it might be possible.

(Picture 2)


A surface of the canvas-structure would be covered with nano-technical springs and little plates of fullerene, and that could give the clothes, what feels normal the capacity to stop the bullet. The thing would go that the short but the powerful punch would make those springs to kick back against the punch.

Nano-springs need special shape, and that's why those things are quite expensive and complicated to build. In that nanomachine is installed little lever, what will pull the spring upwards. The production of the nanomachines would happen with some genetically manipulated cells, what can produce the right molecules, what would be put in the places with the ion-cannons or by the viruses, what has wires, that could transfer by electric fields.


Those viruses seem like some kind of the moon module, and their "feet" would help them to the position in the right point of the ion-pump, what will suck the DNA in the cell, and the cores of those viruses could be used as the nanorobots, what will assembly the complicated nano-machines. In the world of nanomachines could the little electric motors made by cutting the motors of the bacteria away from the cells, and then there will put the very thin kevlar fiber with small iron bites, what can use for moving the nano-submarines.


The problem of complicated nano-structures is that the instruments, what is needed in those processes are very small. That's why the controlling of those things is so difficult. And the production of complicated structures is very difficult, and those things must produce billions.  But if those complicated nano-springs can someday product with mass production, there could be possible to make the clothes, what are covered by those things.
