The new sandwich-type material can offer a breakthrough in superconducting technology.

The new fundamental sandwich-type material can revolutionize superconducting. The anomaly in the quantum hall effect makes electrons travel in that material without resistance. The Hall effect or resistance is the group of standing waves between electrons. The new material can remove those standing waves. It can create a homogenous power field around the wire. Image 2 shows that the Hall effect is like a wall between electric conductors. The quantum-level version is the wall between electrons. If that wall is removed, there is no resistance. 

"Researchers have developed a new “sandwich” structure material that exhibits the quantum anomalous Hall effect, enabling electrons to travel with almost no resistance at higher temperatures." (ScitechDaily, Zero Resistance Breakthrough: Meet the Quantum Sandwich Powering the Future)

"This breakthrough could significantly enhance computing power while dramatically reducing energy consumption. The structure is based on a layered approach with bismuth telluride and manganese bismuth telluride, promising faster and more efficient future electronic devices."

It's possible to create almost room-temperature superconducting conditions using 200 GPa pressure. 

Superconducting has been possible at room temperature, or in -23 C degrees. But that requires 200 GPa pressure. Leak in that kind of pressure system. Is always devastating. How to replace the pressure system? The new material can be an answer to that question.

We can think about things like making superconducting using high-pressure tools. The nanotechnology allows to creation of a small-size high-pressure chamber. The problem is: how to make that system safe?  If there is a small leak in the pressure system releases 200 GPa pressure. One of the answers could be artificial diamonds. They are used to close those high-pressure chambers inside them. 

One of the solutions can be a hollow wire. That wire is put in the channels that lasers drill into industrial diamonds. The system can press pressure in and outside the wire. And that can raise the pressure to a high enough level that the wire turns superconducting. 

In the dry-pressure superconductors, researchers will put a wire lattice between the hydraulic press. Then the system presses the lattice from both sides. Then the system can put and tie the artificial diamond over that structure. Those diamonds can keep the pressure on the wire. 

We can think of an extremely thin material that is used to press the lattice wire and stabilize its structure. The problem is how to stabilize the inner structure. One of the answers to that is the diamond. The system can press the structure into high-pressure conditions and then it can put a diamond or carbonite crystal structure around it. The diamond structure locks pressure into the wire, and that can be the tool for making dry high-pressure superconducting. The system must keep the pressure on the wire or the system fails.

"Dan Cooper" the missing hijacker

FBI:s drawing of  "Dan  Cooper" 

Kimmo Huosionmaa

This is a continue for the last writing. It's a story about the case, what has been the mystery since the year 1971. It is a story of the only man, who hijacked the passenger plane and escaped by the parachute. That man is "Dan Cooper" or "Case Daniel" as some people call this mysterious case, where the man gets on the plane, hijacks it, asks million dollars for ransom, and jumps out there with a parachute.


This man is still wanted, and he presumed to die, but nobody has found his body. There is something strange things in that case because this man could carry a gun to the airplane, and he left some silver powder behind him. The case itself is very well known, and there are many homepages where it is very well introduced. Under this paragraph is a link to this cases "Wikipedia-page".

https://en.wikipedia.org/wiki/D._B._Cooper

Some people think that "silver powder" was the metal called Tungsten, which number in the periodic table of elements is 74, and what is the toughest metal in the earth, so somebody thinks that "Mr. Cooper" was working in the lamp factory because tungstens filaments are made of tungsten.  The reason why this case is so interesting is just how this man able to carry a parachute and the gun to the plane.


Jumping altitude was not so high when he needed extra oxygen if he had good hemoglobin. And when "Mr. Cooper" jumped out the plane over the wilderness in the middle of nowhere, that doesn't mean that this person might not stay alive, if he had clothes, or somebody was waiting for him.  Of course "Mr. Cooper" might change the airplane, using the method, what is shown in the movie "Cliffhanger". In that method will the rope pulled between two planes, and the person who wants to change plane uses the wheel to slip to another plane.


But why this case is so fascinated? That man is not maniac in the normal way.  That metal what was found after he is very interesting because if the gun is made by the antimagnetic material like titanium, chrome-nickel or tungsten it is invisible to metal detectors. And of course, that ammunition can smuggle to the plane in the airtight box.


That is a big threat to airplane security if somebody makes a gun or the knife by titanium he can carry that thing to an airplane. In that case is very much mysteries and some people thinks that "Mr. Cooper" was worked in CIA:s secret aircraft projects. Those projects consist airplanes, what are made outside the bookkeeping of aircraft corporations. Those airplanes are used in some secret operations around the world.
