The metasurface tractor beam.

"Researchers at the ARC Centre of Excellence for Transformative Meta-Optical Systems, TMOS have developed a metasurface-enabled solenoid beam that can pull particles towards it, potentially revolutionizing non-invasive medical procedures like biopsies. This technology, which uses a thin layer of nanopatterned silicon, offers a lightweight, portable alternative to the bulky equipment previously required for such beams.

The acoustic tractor beam is like a tornado. The system must have a hole in the plate and the phonons or some other acoustic systems. Those are on rotating plates and must make the whirl.

The whirl closes the space inside it. The whirl denies the air channel fill from inside it, and then it forms the chimney where the air flows upwards. That kind of system requires, that there is a lower pressure area on the other side of the system.

Multilayer systems make it possible to create low-pressure areas between plates. That increases the system's power. And then the tornado just pulls things in it. The idea is that there is a targeted structure like a whirl that pulls objects in the wanted direction. The thing that makes this structure tractor-ray is that air flows in it, as it flows in a vacuum cleaner.

The phonons that send sound waves to every side of the structure can create the needed vacuum. The phonones can send acoustic waves simultaneously. And that helps to keep the low pressure in that structure where the objects travel in the air tube. This kind of system can remove dirt from surfaces.

The electromagnetic tractor beams require that there is almost zero energy point. Then the hollow laser ray will be shot around that 0 K point, and that laser ray causes the effect, where energy starts to travel to the 0K point in the bottom of this ray.

The coherent radiation travels like strings, and there should not be standing waves in the middle of the laser rays. The standing ray forms because of scattering. In long-distance models, the system must clean air using water or something like that to deny standing wave formation.

So outside energy pushes particles in that channel. And that kind of system is a fantastic tool for submolecular- or subatomic technology.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
