Solar Impulse 2, l’aereo ad energia solare elvetico che tenterà nel 2015 di fare il giro del mondo lascerà la sua base a Payerne, nel canton Vaud, a inizio gennaio, probabilmente martedì 6. Lo hanno comunicato sabato le forze aeree.
Il velivolo verrà caricato su un aereo cargo 747 che si dirigerà alla volta di Abu Dhabi, negli Emirati Arabi Uniti, città di partenza e destinazione di Bertrand Piccard e André Borschberg per l’impresa che dovrebbe durare 5 mesi, da marzo a luglio.
Costruito in fibra di carbonio, Solar Impulse 2 ha un’apertura alare di 72 metri per un peso di 2'300 kg. I suoi quattro motori sviluppano energia grazie a 17'000 cellule solari che ricaricano 633 kg di batterie al litio.
