Benefiting asteroid belt

Benefiting asteroid belt

When we talk about benefiting the asteroid belt we somehow forget that most of the asteroids are quite small. Delivering them to Earth is quite easy because the gravity of the Sun would help in that process. And the needed energy is lower than sending stuff to the asteroid belt. But the problem is how to get the energy to that area.

The system can use the power satellites that are delivering energy to the space stations and other systems at the asteroid belt by using the maser or laser rays. The problem with the power supply is that sending uranium to that area is very expensive. So the uranium must be found from the asteroid belt or some other power source must be found that this kind of thing can make in real life.

Sometimes I have read that the space station orbiting Ceres gives a new home for humans. The fact is that it might work as the simulation for the larger-scale space stations, which might cruise in the solar system in farther future. There is one problem with asteroid Ceres, and that is the weak gravity. And that means the satellite or space station would rather saying follow that asteroid.

The station would have a tube or drill, which it can use to conduct water from Ceres straight to the station. The asteroid belt is a very interesting place for the space industry and research. The gravity of asteroids is very weak. And that means that the benefiting asteroid is "very easy".

In principle, an asteroid can equip with ion rockets and send them to Earth. The ion rocket can get energy by maser or laser rays. But there are also more interesting ideas for sending asteroids to Earth.

The material can transport to Earth by using the shuttles, which is pulling the asteroid to the Earth orbiter. The other version is to use the giant sling or magnetic accelerator or rail gun. The problem with magnetic rail-gun is that system requires a magnetic piece where the magnet can touch. So it can use only for sending the iron asteroids to Earth. Or the material can pack into the capsule which can accelerate by using magnets.

The sling could be over hundreds or thousands of kilometers long wire, where the asteroid will connect, and then it will send it to the trajectory, which transits it near the Earth. In both cases, the asteroid would equip with the retrorocket and probably with a safe explosive, which can explode the asteroid if it goes to the wrong trajectory and treats Earth. So what is the size of the asteroids, what could be sent to Earth? Their size would be about tens to hundreds of meters. And that means they would not very big.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low. The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away. When the box is filled with quantum gas and som...

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 t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull. The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
