ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a traffic system or a traffic method, and more particularly to those where the moving path is substantially fixed.
BACKGROUND OF THE INVENTION
There are many methods to interpret the human developing history. It is not too much exaggerated if we hold that it is closely related to how the traffic system or vehicle is developed. In brief:
1) Animal power: It is easily exhaustive no matter how many animals are involved in use. The endurance, power stability and power output are relatively limited;
2) Human power: This is limited to the diversification and/or function-multiplication of the bicycle or canoe or the like and has the same limitations as above described since broadly speaking, this is a kind of animal power;
3) Natural power: Artificial utensils, e.g. sailboat, glider, hot-air balloon, raft . . . etc., are driven to move by the possibly existent wind, tide or water potential difference in nature. It goes without saying that we cannot accurately control their power stability and power output and when they can be put into use; and
4) Electric/Mechanic power: Although vehicles powered by any one of the above three kinds of powers are improved in functions with the changing time, it is necessitated that they are limited by their inherent characters. Since the steam engine was invented by James Watt, trains, cars, motorcycles, containers, oil tankers, aircraft carriers, submarines, airfreighters, fighters, airplanes . . . not only all have a rigorously advanced performance but also can be powered to move in an extremely high speed. Since information about these is easily accessible, no further description relating thereto will be given here.
In the striving process for development of the human society, it is often moving to find how the pioneers always sticked to their dreams or ideals. Perhaps, most of them failed. Nevertheless, a few examples of success have successfully built this world of nearly satisfactory technological civilization. Among the above 4 categories, a new category was constructed by a new underlying idea. In eastern logic or philosophy, the human being is closely related to the nature and it is a great task to pursue a harmony therebetween. As such, it is strongly believed that a spectacular or revolutionary creation must originate from such deep but clear inspiration or philosophy. The Symphony No. 5 in C minor, i.e. the so called Fate Symphony composed by Beethoven was enlightened from the voice the landlord knocked the door, which is a good example for what we just mentioned.
The applicant was born at An-Ping Harbor, Tainan, Taiwan. In his childhood, the shock that a hand with a small force could push so big a harbored fishing boat still remains in his present mind. After grown to have the opportunity to get known to the fact that the Dead Sea or Salt Lake exhibits a greater buoyancy, the above shock becomes oscillated in his mind now and then. The present invention was suddenly somehow conceived. In sum, the present invention aims to power a buoyed-up vehicle by the power available on land in order to obtain a conveying medium being even faster or energy-conservative.
Specifically, a traffic system according to the present invention includes a passageway built on a land and defining a moving direction, a buoyant fluid contained in the passageway for generating a buoyancy while displaced, and a vehicle arranged to move in the passageway along the moving direction with the buoyancy from the buoyant fluid. We will compare how the general land vehicle and the present vehicle differ from each other while performing the work:

According to the above equations, we can design the desired characteristic shape of a specific vehicle.
It is therefore attempted by the applicant to provide a new style of vehicle as above-described.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide a new style of vehicle.
It is further an object of the present invention to provide a new traffic method.
It is another object of the present invention to provide a vehicle system having a relatively low construction cost.
It is still an object of the present invention to provide a vehicle system having a low operation cost.
Specifically the essential concept of the present invention might be regarded as something like “to move a boat on the land.” In other words, the present invention tries to take advantages of moving the boat for the vehicle on the land. A “boat” referred to herein is not limited to any specific kind of boat or ship. Any kind of boat or ship, e.g. an air-cushioning boat, which is appropriate to be mounted or powered in the present predetermined passageway is proper. Certainly, for achieving the above-described objects, we must consider various variables and then adjust various parameters according to the above-referenced equations.
According to a first aspect of the present invention, a traffic system includes a passageway defining a moving direction, a buoyant fluid contained in the passageway for generating a buoyancy while displaced, and a vehicle arranged to move in the passageway along the moving direction with the buoyancy from the buoyant fluid.
Certainly, the passageway can be made of a material selected from a group consisting of glass, fiber-reinforced plastics, reinforced concrete, steel reinforced concrete and stainless steel. The buoyant fluid can be one selected from a group consisting of water, sea water, condensed sea water, water with an additive, sea water with an additive, and any one which can float thereon the vehicle.
Preferably the present system further includes a control agent for controlling a constituent of the buoyant fluid wherein said control agent controls a specific weight of the buoyant fluid. Such control agent can be condensed sea water having a specific weight ranging from 12 to 16 kN/M

, or an additive for increasing the specific weight of the buoyant fluid.
Preferably in the present system, the vehicle further includes a specific weight detector for detecting the specific weight of the buoyant fluid. The present vehicle further includes a vessel for storing the control agent for releasing the control agent into the buoyant fluid when the detector detects that the buoyant fluid has a decr
