Pipeline Transportation

Today in class we discussed the various ways to transport goods from point A to point B. One of the ways was pipeline transportation. I was unsure of what exactly it was, so I looked it up. The definition of this is, "the transportation of goods through a pipe. Most commonly, liquids and gases are sent, but pneumatic tubes using compressed air can also transport solid capsules." Pipeline transportation can be utilized for a number of different goods that include, oil or natural gas, ammonia, biofuels, coal, ore, hydrogen, water and beer. As far as beer is concerned, one major brewery in Germany uses the pipeline to transport beer to large stadiums because of the fact that it uses one central tank. Overall, this method is used mostly for liquids and not solids, however, solid capsules may be utilized in rare occurrences. 

Do you think that transportation through a pipeline is beneficial, had you heard of this method before?
