fantastic electromagnet

So fierce that scientists at NASA (National Aeronautics and Space Admistration) began to think to use it as a force that can 'throw' a spaceship to the outer atmosphere of the earth! Why till this idea? Is not rocket engine that was used to send the planes out of the ground was quite successful? Actually all the rocket engines that have been used or are being developed currently still requires special materials as a pusher. This propellant ingredients can include such chemicals are already widely used, could also be the result of nuclear fusion technology is developed in the early 21st century. There is another variety of innovative technologies such as light Propulsion Propulsion and antimatter.

Propellant usage is actually very limiting speed and maximum distance the plane can be achieved. That's why there is an idea to send out a plane
space using technology that did not involve the propellant. What the system can 'throw' the plane is so big and heavy into space without using a propellant at all? Only Elektromagnetika can answer that!

Elektromagnetika is a combination of electricity and magnetism. As we provide electricity on a wire we can create a magnetic field. Electricity and magnetism really inseparable except in type I superconductors showing Meissner effect (superconductors materials can eliminate the magnetic field to some extent). This can be proved by putting the compass near the wire. Pointer on a compass needle will move as a compass to detect the existence of a magnetic field. Elektromagnetika
has been used in making motors machines, tapes, videos, speakers (speaker), and so forth. Now turn to outer space projects that want to take advantage of virulence!

David Goodwin of the Office of High Energy and Nuclear Physics in America is the one who proposed the idea of this electromagnetic Propulsion. When an electromagnet is cooled to extremely low temperatures occur something 'unusual'. If we provide electricity on a super-cool magnets, we can observe the occurrence of vibration (vibration) for a few nanoseconds (1nanodetik = 10-9 seconds) before it becomes superconducting magnet. According to Goodwin, although this vibration occurs only during a few nanoseconds, we can still take advantage of unsteady state (not yet achieved steady state) this. If the vibrations are created can be directed to the one in the same direction then we can get enough power to 'throw' a spaceship. This strength is not just enough to 'throw' is arbitrary, but precisely a spacecraft can achieve maximum distance even further with a higher speed of all kinds of aircraft that use propellant.

To explain his idea, Goodwin uses a wire coil (solenoid) made from superconducting magnet wire wrapped around the cylindrical metal rod. Magnetic wire used is niobium and tin alloys. This becomes superconducting electromagnet materials after cooled using liquid helium temperature to 4 K (-269oC). Metal plate under the solenoid serves to reinforce the vibrations are created. To occur with a frequency of 400 000 Hz vibration, necessary to create conditions of asymmetry in the magnetic field. Sheet metal (can be made of aluminum or copper) that has been given the voltage is placed separately (isolated) from the solenoid system in order to create conditions of asymmetry.

For a few microseconds before the magnets begin oscillating in the opposite direction, there is electricity in the metal plate must be removed. The main challenge that still must be overcome is a technique for directing the vibrations which are formed on the unsteady condition, so they all move in one direction the same. For that we need tools
Such switches (solid-state switch) that can be turned on and turned off the electricity 400,000 times per second (ie in accordance with the frequency of vibration). These solid-state switch is basically to take energy from the steady state and turn it into electrical pulses at high speed (and containing high energy) up to 400,000 times per second.
Energy used for the electromagnetic system is derived from a nuclear reactor (300 kW) owned by NASA. This reactor produces heat through nuclear fission reactions. Nuclear fission reaction involves atomic fission process accompanied by gamma radiation and release heat (thermal energy) in huge quantities. Nuclear reactors that use ¾ kg of uranium (U-235) can produce heat equivalent to heat generated by burning a million gallons of gasoline (3.8 million liters). Thermal energy generated
nuclear reactor was then converted into electrical energy that can be used for this Propulsion electromagnetic system. When used in the aerospace, ¾ kg of uranium did not take place because it only requires the room for baseball. With mass and space requirement is much smaller than the rocket engine that was used to send the plane into space, the plane that uses an electromagnetic system can achieve maximum speeds much higher
so that it can reach more distant locations as well.

According to Goodwin aircraft with electromagnetic technology, it can reach the heliopause, which is the meeting place of winds coming from the Sun (solar wind) with the wind coming from a star outside our own solar system (Interstellar solar wind). Heliopause is located at a distance of about 200 AU (Astronomical Units) from the sun. 1 AU is Earth's average distance from the sun that is about 1,5.108 km. Farthest planet in our solar system alone is only 39.53 AU from the sun. All of a spaceship that uses propellant can not reach that distance!

Of course aircraft armed with this powerful electromagnetic still very far from an ideal system we want. Because even though the plane can reach very high speeds, the speed was still very small compared to the speed of light (300,000 km per second). The maximum speed can achieve this system is still below 1% the speed of light. Though the star closest to our own solar system is at a distance of more than 4 light years (one light year = 300,000 km / sec x 60 seconds / minute x 60 minutes / hour x 24 hours / day x 365 days / year = 9,4608.1012 km ). Furthest trip ever taken by human beings is 400 000 km (ie trips to the moon).

If we want to send a UAV, we still need hundreds of years before the aircraft could reach the nearest star. That, too, because the plane uses electromagnetic technology! With aircraft using the new propellant chemicals we can reach the nearest star within tens of thousands of years. If we want to reach the nearest star in a faster time in the Star Trek like we need a technology that can exceed the speed of light. During the technology is still
can not be developed, we can use a first teknologielektromagnetik which turned out to offer an alternative that is promising although not yet able to realize our dream to explore the universe.
