This paper presents a model of energetic consumption and photovoltaic production for a large airship which acts as feeder connecting the ground with a large cruiser. The analysis of energy needs and productivity allows defining both an ideal sizing and operative mission profiles. The specialised mission of this airship is to ascent and descent. It includes also the connection with the airport buildings on the ground and with the cruiser at high altitude. Photovoltaic production has evaluated in terms of hydrogen and electric propulsion. They have estimated both and a calculation methodology has proposed. The evaluation has supported by CFD evaluations on aerodynamic behaviour of the system at various altitudes.

This paper presents a novel concept of acclimatized container to increase people comfort in case of temporary housing. It is based on the ZEBRA concept (Zero Energy Building Renewable Addicted) concept studied by Università of Modena e Reggio Emilia. The original concept developed for industrial building has been extended to mobile metallic housing systems such as the containers transported by trucks which are used for troops and military command during field operations. This system does not require any external source of energy. It requires only the presence of a water well or drilling a hole to place inside a closed loop exchanger which is used to stabilize temperature of internal water which is used as a dynamic thermal barrier which maintains in the wellness conditions inside the mobile housing equipment. Energetic costs of this system are related only to the very reduced energy necessary for water pumping operations.
