Skytrain to Nowhere is an imagination driven and esoteric volume of free-form poetry. The book documents the author’s experiences, thoughts and observations while riding the skytrain at Phoenix Sky Harbor International Airport over the period of several weeks. Since the skytrain is only designed to transport travelers between various terminals and parking facilities at the airport, someone spending nearly 50 hours riding it purely for recreation and artistic inspirational purposes is highly unusual (to put it mildly.) Aside from occasional quirky anecdotes about various passengers, the poems mostly deal with themes of motion, the passage of time, and nostalgia. The author grapples with these issues from a retro-futurist perspective. Skytrain to Nowhere celebrates the realization that our vitality hinges on our ability to always keep moving, while recognizing we are unwilling or unable to leave some things behind on the journey.
Laser guns are something you’ve probably only seen in science fiction, like Battlestar Galactica or Buck Rogers in the 25th Century. Few people realize though that laser guns are about to become a reality because scientists have been experimenting on ways to create handheld laser guns for quite some time. These guns are actually referred to as “directed energy weapons.” You probably know lasers as being beams of light that are narrow and highly concentrated. But what real laser guns do is release highly focused energy towards a specific target that the shooter wants to damage. The gun has to be held still because the laser needs to make continuous contact with its target. Real handheld laser guns aren’t like what you see in Star Wars where a visible red or yellow beam shoots out of the gun repeatedly like bullets. Instead, a beam of powerful light will burn the target continuously as long as the laser stays pointed at it. To give you an idea of what this laser looks like, watch the classic James Bond movie “Goldfinger” and look at the scene where the laser gun shoots down at Bond as he is strapped to a table. Now imagine that same laser coming out of a handheld gun. This is a good representation of what a real handheld laser gun will do.
Laser energy is typically produced through electromagnetic radiation. The amount of watts of the energy is what determines how powerful the laser will be. Laser technology has actually existed in the consumer marketplace for quite some time. Have you ever heard of laser pointers? These are handheld devices that produce a laser in which you can point to things with. All you will see is a dot of light on the target and not the full beam because the light is not powerful enough. Now you are probably wondering why laser pointers don’t cause any damage to the target. Well the reason they don’t is because laser pointers only use .005 watts of energy. The U.S. Navy has a laser cannon prototype that is 30,000 watts, which can actually shoot down a drone flying in the sky. Therefore, this should give you an idea of how the number of watts makes a difference in its level of destructiveness.
The Soviet Union in 1984 also had a prototype laser pistol.These were intended for use by Russian cosmonauts to take out optic sensors on enemy spacecrafts. It was apparently a ruby laser and may have worked by a synthetic ruby rod, which would be pumped with high energy and very bright light from a flashtube. The ruby rod would then send out a short burst of laser beam. The pistol had an effective range of about 20 meters.
Thanks to the internet, people can now learn how to make their own handheld laser guns at home. One can also find laser gun demonstrations on YouTube where people have made them at their house. These guns typically have 40 watts of power to them, which is enough to cause a fire on the target and do some damage. You should take caution when trying this for yourself(in fact, don’t do it at all.)
For years the term “tractor beam” has been synonymous with the science fiction technology that we see in movies, television or read about in books. Tractor beams are basically beams of energy that have the ability to move objects or pull objects closer to the source of the beam. Some fictional examples of tractor beams include the Enterprise in “Star Trek” and the common theory that flying saucers have the ability to lift people into their ships through a tractor beam at their base. But now, tractor beams may become part of real life the same way mobile phones have become part of real life, even though they were once considered science fiction as well.
The emerging tractor beam technology seems to be starting with a sonic tractor beam created by British scientists which has the ability to turn, levitate, pull and push objects. This beam is dependent on a sequence of sound waves that are timed precisely in order to create an area of low pressure which can trap objects that are small. Then the sound waves are used to move the objects around as they please. However, this technology can only work on small objects at the moment. British scientists and researchers from the University of Sussex and the University of Bristol have been able to move particles that have a diameter of up to 3.1 mm. In order to do this, they used acoustic transducers to create acoustic force fields that could move these objects. Even though these objects are small, it makes scientists wonder how this technology can be advanced into other areas later on down the road. For example, this tractor beam technology could be used to manipulate cells within the human body and cause them to move too. This could do wonders for treating patients and advancing modern medicine.
This tractor beam technology is still in its infancy stage. Speculation surrounding it suggests that law enforcement officers of the future will be able to have non-lethal weapons using this technology that can stop attackers or suspects at close range. As the technology grows into moving bigger objects, the possibilities are endless. The military could build bases through acoustic force fields or catch planes in the air that are about to crash on the ground. We might not even have to fight wars anymore with boots on the ground because we will eventually have the ability to move objects on the ground through a tractor beam in outer space.
