Solar Impulse 2 ha completato lunedì mattina il suo primo volo di prova sopra Payerne. Il velivolo, decollato alle 05.37, ha completato il test in condizioni ottimali, nonostante un po' di nuvolosità e qualche residuo di pioggia.
L'atterraggio è avvenuto dopo 2 ore e 15 minuti. L'aereo, alimentato esclusivamente con energia solare, è il più rivoluzionario mai costruito finora. Possiede un'apertura alare di 72 metri ed è dotato di oltre 17'000 cellule fotovoltaiche al silicio.
È in programma per il 2015 il tentativo di completare un giro intorno alla terra, sfruttando esclusivamente l'energia del sole.
