Proponents point to the enormous energy density of the fuel (the amount of energy contained per unit).

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation.

While proponents of deregulation point to lower fares between high density hubs, these bargains are subsidised by exorbitantly high fares for flights between the thousands of smaller cities across the country.

Figure 2 in the accompanying power point file shows historical storage areal density (AD) growth for HDDs (this is directly related to the amount of digital storage that can be put on a disk in a hard disk drive) from Q1 2000 through Q1 2011.

At some point in Hong Kong, no matter how careful you are to keep to quiet streets, the density of the city will start to close in.

Opponents point out that unlike areas in other countries, mass transit is only economic viable in areas with sufficient density and that on a large scale, massive public transit programs have no chance of becoming self-sufficient.
