HW 9

Introduction:
1) History of transportations:

The beginning of transportation was about 3500BC when fixed wheels on carts were invented, and also River boats which were ships with oars were invented. And then about 2000 BC horses were used for transportations. Then between 181-234 the wheelbarrows were invented. Then in about 770 the transportations were improved when iron horseshoes were invented. Then in 1662 Blaise Pascal invented the first public bus which was drawn by horses, this bus was in a regular route, schedule, and fare systems. Then in 1783 the first practical steamboat was demonstrated by Marqis Claude. Then in the 1790 steamboat invented. In the 19th century were a lot of invented; the most popular were gasoline engine automobile, compressed air locomotive brake-enable trains, and cable car. Then in 20th century we had more indentations, like airplane, helicopter, hydrofoil boats, hovercraft, and a lot of things.

2) Kind of transportations applications can be reached in the future:

Kind of transportations applications that we will have in the future depended on how much the price of oil will be. Even though oil price has never got changed the transportation will get changed, but I think the oil price will be the biggest be affective on the future transportation application especially of the oil price gets increased. So if we assume that gas price will get increase, engineers will work harder to make vehicle cost less gas, or make them work with something else than gas.
New we already have started to have new kinds of vehicles that work some time with gas and sometimes with electric power. For example Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.


3) What is passable and what is not.
Kinds of transportation we may have and may not have are depended on the time, so transportation will get improved depending on time. for example in the ten years from now it is most likely that we will have cars that can park by themselves, cars that will predict the future, cars which will talk to the road and the road talk back, and many different features.


4) Issues we may face in the future.
I do not think that we may have lots of problems comparing with advantages that we will have gain with the new transportation features.

5) Conclusion:
Transportations will get improved step by step with time, but the improvements will get faster with future, and we can see that by looking at transportation history. We noticed that transportation in the past had moved very slowly, and it has gotten faster movement with time, so what I expect from transportations in long future will be something untenable now.
