"Santa Claus" machines and nanotechnology.

Acoustic holograms can make the "Santa Claus" machine possible. 


"The team was able to use their technique to print 3D objects from solid microparticles, hydrogel beads, and even biological cells — contact-free (bar the sound waves, of course)". (BigThink.com/German scientists 3D print objects with “acoustic holograms)

The acoustic pressure systems can use to model metals or ceramics. In the most conventional versions, the LRAD systems can use air as the hammer that models the ceramics or even metals and carbon fiber. 

Acoustic holograms are 3D-shaped pressure fields created by high-accurate sound waves. Those pressure fields act like hydraulic presses. And they can create physical merchandise by pressing the plastic foam or plastic fog created by using high-temperature systems. 

The acoustic holograms can make things even from metal dust or metal vapor in extremely high temperatures. In some visions, laser rays are vaporizing metals of carbon fibers. And then the pressure system starts to press that vapor. The system creates acoustic holograms by using synchronized extremely small-size LRAD systems. That the 3D printing systems can make the right pressure shape. 



But nanotechnology needs even more fundamental tools.


Most nanomachines are created by using carbon. In modern nanotechnical systems, the laser and highly accurate electron rays are used as billiard sticks that push carbon dioxide molecules into the right positions. The carbon and oxygen atoms are creating new types of materials that can be used in nanorobots. 

The carbon molecule chains can use in the shell or structures in nanomachines. The nanomachines can form larger structures. And in some visions, the nanomachines can use to create metal plates that fix themselves automatically. 

AI-controlled systems have no limits. They can create small protein fibers. Those proteins can use as nanomachines by connecting some enzymes to them. In some wildest visions, those proteins are covered by magnesite, and they can operate as miniature mass memories that control nano-sized robots. 

In those cases, protein acts like a miniature tape drive. That can control microchips. And those microchips can drive cell-size cyborgs to the right positions. Those cyborg cells can be macrophages that clean blood systems. In some other versions, the artificial DNA controls those systems. Maybe somewhere in the future. The living neurons can control nanomachines. That allows us to create a structure that can be as highly intelligent as humans. 

The acoustic systems can protect the manufacturing process of those machines. They can protect the platforms that might hover in the chamber where the electrons and photons are pushing the nanomachines in the right positions. Nanomachines and nanotechnology are tools that have no limits. 

Some nanomachines are not even work in high temperatures. Those low-temperature operating systems can hover above the superconducting layer. And they can use to move other molecules. But maybe in the future, those nanorobots can participate the missions to frozen moons like Triton at the solar system's edge.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

  Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.  Could a hypothetical Planet X tunnel all radiation?  The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory.  And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact.  In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells.  Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
