At the expense of aerostatic lift gas filling the shell to lift and move cargo airship units require much less power than other aircraft. Accordingly, it needs much less fuel. Especially with the possibility of implementing projects on the placement of solar panels on top of the shell. Meanwhile, aviation fuel all going up and up in price. At the same airship engines can use a cheaper fuels, including gas. Already it is estimated that freight airships, even for the European territory of Russia is very cheap. Transportation of the airship is cheaper than transport by helicopter in 20 – 25 times by air to 8 – 10 times by car a good road in 2 – 3 times.

And on the roads at all airship out of competition. The effectiveness of an airship depends on its size. One cubic meter of helium at normal atmospheric pressure provides a lift one kilogram load. So, to lift 10 tons of payload, subject to its own weight airship takes to fill a shell around 20 thousand cubic meters of helium. So profitable cargo airship, by definition, must be large airship. This requirement is based on the fact that small amount of gas airships have characteristics of low weight payload. Only aircraft with a capacity of not less than 60 thousand cubic meters can lift the weight of 12-15 tons. That is, the weight of a cargo container. For a better understanding of this fact can be compared to technical data of the largest airships of the twentieth century.
