• the first conveyor 8 is fit to direct the Aeolian flow flowing out from the lower turbine
• the truncate cone shaped portion of the first conveyor 8 comprises a plurality of passing openings 18.
• the movable blades 13 of the lower turbine 4 are helical shaped and the movable blades 14 of the upper turbine 7 are wing shaped or propeller blade shaped fixed to the shaft 3 by means of a hub 15.
• the movable blades 14 of the upper turbine 7 are approximately disposed on several horizontal planes, for example four planes, and each of said planes comprises a set of blades, for example eight blades, disposed to form a respective disc of the blades.

• the machine comprises a lower evaporator 10 and a upper evaporator 22.
• the lower evaporator 10 is disk shaped and is placed immediately below the turbine 4 in order to supply at least to this latter also water vapour.
• the upper evaporator 22 is approximately annulus shaped and it is associated with the enlargement 9 of the first conveyor 8 in order to supply the interspaces 21 also with water vapour.

• the operation of the machine by means of the turbines, provides to maximize the use of the air kinetic energy driven by the wind and by the convective motion produced by the air heating and by the air humidification carried out by the evaporator means which makes the maximum use of the thermal energy collected by the solar collection means.
• the machine is therefore able to supplying electric energy also in case of lack of one of the two Aeolian and solar sources.

• An advantage of the present invention is to provide a machine to obtain a significant electric power production from renewable sources also in lack of wind.
• Other advantage is to provide a machine with moderate environment impact.
