The deepest hole on Earth


The deepest hole on Earth

The super deep borehole in the Kola peninsula is one of the deepest man-made holes on Earth. The depth of that hole is 12 262 meters, and the name of this hole is officially SG-3.  Soviet scientists stopped drilling when temperature rise 180 degrees Celsius. Sometimes the temperature is meant to be 300 degrees of Celsius. In the Sakhalin island is the hole, what depth is 12 345 meters. And in the Kuwait oil field is drilled the borehole, what is 12 285 meters deep, and as you see, there is the technology that is used in those holes includes very tough steel.

The thing that the drill would not able to operate in the 180 degrees Celsius is sometimes wondering me because the blades of the drill would not stand the temperature of 180-300 Celsius. Those blades are made by using Chromium steel, and the thing is that those materials would not melt at a very low temperature. The melting point of the chromium is 1800 degrees Celsius, and the thing, what happened might be that the hydraulic oil or lubricant would be steamed or started to burn.

By using the laser drill is possible to create even deeper holes, and the laser drill is actually the laser, what is used to make a hole to the Earth.  The idea of those super deep holes is that scientists tried to drill the hole straight to magma, and sometimes there was introduce thoughts that there is possible to make the probe, what travels inside the nucleus of the Earth. There have been introduced the plans, what kind of vehicle could be the probe, what can be sent to magma.

The craft, what would send inside the magma would be an absolutely round artificial diamond ball, what will communicate with command center by using the sonar and LRAD system. The thing what would be the most important in those crafts is, that the ball must be absolutely symmetric because it must resist the extreme heat and temperature.  The craft, what could be made by the artificial diamond, what would be the carbon fiber, that made tougher by pressing it with explosives. The carbon fiber would be protected by the iron, and that would isolate it from magma. The probe can use nanotechnology and it can be the size of the ping pong ball or even smaller.

The system might have two layers, and there would be a vacuum between those layers. In the simple model, the inner ball would hang to the outer ball by using metal wires. The magnets would keep the inner ball separated from the outer ball, and that could make possible to create the craft, what can dive in the nucleus of the Earth by using the electromagnetic drive, what can take the needed energy from the heat of the magma. But of course, this thing is only a theoretical way to travel in magma.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
