A couple of words of radio-waves and spectroscopy

The most modern radar technology bases the same technology, what is used in the radio astronomy. One of the most interesting parts of this technology is so-called radio-spectrometer, what is used to determine the elements what is in some target. Those echoes can be separated by using Prisma or hila, what would help to get the spectrum visible. And the black lines in the spectrum are caused by the elements, what is sending the radiation.

Radio-spectrometer works like normal spectrometer, what would send to the laser-ray to the target, and then every atom would send the radiation in their unique frequency. Every element in the universe has the own frequency of electromagnetic radiation, and that would help to detect the elements what the target consists. The radio spectrometer would work in the same way, but the echo, what the elements would give are coming in the radio-frequency, but the methodology that is used is similar to the normal spectroscopic.

The reason for those dark lines, what is seen in spectroscopic photos is that when some element sends the radiation, would that wave movement cause that the waves would weaken. Actually, that phenomenon caused by the polarization of that frequency. Some scientists believe that this phenomenon can be used to make an object invisible in the frequency of light. Every electromagnetic radiation can be turned away from the object like radio waves, and in theory is possible to make the form where the light would travel across it like in STEALTH-aircraft.


Another way to make some object invisible to the human eye would be used the led-light, what would suppress the waves with counter waves, that the light would not snap from the surface of the object. But this technology needs that every frequency of the electromagnetic radiation must be suppressed differentially.  This means that every frequency of the spectrum must be made own led-lights, what would send the counter light exactly with the same power and frequency, what the incoming radiation has.


The effect is similar like in scenario, that somebody would send the counter waves from the beach to sea. If the counterwaves could send against incoming waves they would suppress even the large tsunamis, because every wave, what would hit the tsunami, will decrease its energy, but, of course, the huge turbines can be used against those waves, but this technology needs large-scale investors. And that's why this is possible in the distant future.

The "impossible motor" and what is so problematic with it?


"Project Pluto"
(Picture I)

Kimmo Huosionmaa

There would be no motor, what can work without propellant. There is little bit difference between fuel and propellant in rocket technology. Fuel is the thing, what gives power supply for those spacecraft, and propellant is the thing, what gives thrust for the rocket. In the case of electromagnetic or nuclear rockets is very important to separate terms propellant and fuel, because those motors don’t need fire for giving speed for those spacecraft.


The  so-called impossible motor is one part of so-called electric drive motors, what would use electromagnetic radiation for giving speed for spacecraft. I sometimes wonder, why that team uses microwaves because the radio frequency would be safer, and the system could be cooler. Those motors cannot even work in the atmosphere, because the full thrust force of the electromagnetic radiation is so small.  This motor uses electrons or radio-waves as a propellant, and that's why they would not break the laws of physics.



In some scenarios in the rockets, burning camper would create the electric arc, and hydrogen would drive thru it, and it would give very high speed for that rocket. But the pure electromagnetic rockets would use only the radiation, what gives the very high-speed impulse to back but the problem is very low thrust, what means that this rocket must shoot to space, by using conventional rockets, and then that spaceship would accelerate near the speed of light by using some other motor solutions.



So those rockets must launch to empty space that those motors can be work. Those electromagnetic motors are in theory use photons or radio waves to accelerate the spaceship to the speed of light. There are three types of electromagnetic rockets, what are planned. They are pure electromagnetic motors, what uses photons, radio- or microwaves to create the thrust. Another way is to anti-matter to create the thrust or third way is to use the magnetic field to accelerate the atomic particles. When the electromagnetic motor work, it actually needs fuel to create electricity for its transmitters. And when we are looking at that kind of motor, we can say that the thing, what gives thrust to the rocket is called as a propellant. So those motors actually use electrons or photons as a propellant.



There is one problem, and it is very low thrust, what means that the spacecraft must accelerate near the speed of light by using some other rocket systems like antimatter. That would give that rocket the speed, what is near the speed of light, and then the radio-motor would be started, and that would allow the spacecraft to fly to the speed of light. There is one version of those radio-motors what might have the capacity to fly in atmosphere. That motor is called as "electric arc jet motor". In this particular motor, the radio-waves are made for creating the electric arc in the tube, and that would replace burning in some very powerful engines. That motor would look similar, then what is created for "Project Pluto".



In that project , U.S Air Force created an idea of the nuclear jet motor, where in the middle of the ramjet-motor would be installed nuclear reactor, what would warm the air, what would drive backward of that motor. But when political atmosphere turned against that kind of solutions, started NASA think about the possibility, that this nuclear reactor would be replaced by using electric arc. And when this motor would be equipped with flap system, what was planned to be similar, what was used in V-1 "Flying bomb" could be possible to make the motor, that uses air as a propellant. Also, there were plans to make aircraft, what uses electric arcs to hang in the air. In those planes would be the chamber in the middle of them, and if there would make the electric arc, with power what is enough high, would that allow the aircraft to fly in the atmosphere.



That rocket would use fuel cells to make very high voltage, what makes electric arc under that plane. And in this case, the electric arc works like the fire under heat air balloons, what are used for centuries. Many of those robots are at the theoretical level, and the solutions would be waiting many years. But one spacecraft have used ion motors while traveling in the asteroid belt. and that would give change to develop more powerful and sophisticated rockets for the space exploration, and maybe we would travel to another planet by using some of those rockets, what are only pictures in the papers.

Clouds are fascinated people during all the history.

Clouds are interesting things because they can get the very strange form, and one explanation for UFO:s is strange looking cloud objects. The objects in the sky might look like the space shuttle or STEALTH-aircraft. The reason for that is not actually have been explained, but sometimes the forms of the clouds are probably caused by some strange energy field. I mean that making forms to the clouds is actually very easy, and the technology that is used is the normal radio transmitter, what has two synchronized targeted radios, what operates at the same frequency and same time.


That system can cause the electric arc in the sky, and that might cause reports of UFO-phenomenon. Those electric arcs might make for making rain because of that phenomenon would cause the forming of drops. And that electric arc can be very dangerous if some aircraft fly thru it. Use of those systems must be done by under control of authorities because they are really dangerous things.


But then we must ask one question: why would somebody want to make images to the clouds? There are rumors that in "Bermuda triangle" the clouds are forming some kind of "tunnels" when the aircraft is starting to shake. That formation of the tunnel might be caused by the high power micro- or radio waves, what are targeted to that aircraft. So maybe the United States Navy or Air Force test high power detection and electronic warfare systems in that area.


Also the weapons, what bases the electric arc can be tested in that area. There would need only two radio-systems, where is two targeted radio transmitters, what just crosses their radio wave at the certain point. That device would be more devastating, than some grenades. But it might be used also in the systems, what are made for weather modification, and also it can be used to make plasma-layer in the atmosphere, what mission is to make thermonuclear warheads detonate in the wrong altitude.
