The storage batteries are in fact used only during take-off and landing. 
Lightweight materials and innovations such as aluminum, carbon fiber and composite materials, the result of the aerospace research, will optimize shape and firmness of flight of the airship enhancing its stability. 
The average cruise speed at full load will be 90 km, with peaks up to 180 km, with the possibility to travel to altitudes varying between 500 and 2500 m. and to be able to land anywhere you want. 
The airport is designed to cooperate with the Photovoltaic system of the airship and the battery energy storage, minimizing waiting time.

The solar airship is composed by 4 levels:

1° level dedicated to 8 helium tanks, independent from each other and hermetically sealed;

2° level dedicated to technical support: storage batteries for engines and other materials;

3° level multipurpose airship for client activities. Allows to take advantage of 1400 square meters adaptable to various needs.

4° level dedicated to crew and pilot & control systems of about 400 square meters.
