The soon to be implemented testing installation, is sized to operate at an altitude of 200 metres using two aerostatic balloons of 6 metres in diameter. Structural calculations are described in the following section “Yield” and the prototype functioning is shown in the next 4 illustrations.

In the first illustration, the aerostatic module is pushed by the wind for about 300 metres thanks to its opened parachute. 92% of wind power is thus transformed into electrical energy by the rotation of a generator while the remaining 8% is used by the simultaneous lifting by about 2 metres of a cubic metre of granite.

The second illustration shows the aerostatic module as it closes its parachute and moves back along its path exploiting the potential energy of the mass on the ground. The duration of this phase is equivalent to the preceding one, roughly one minute in which no electrical energy is generated.

Illustration 3 shows the phase in which the aerostatic module is pushed by the wind thanks to the opening of its lower parachute and it generates electrical energy and lifts the granite mass. The last illustration shows again the situation described in illustration 2: the preparation and the beginning of the cycle (illustration 1).
