According to the pv-magazine :

“The world’s largest solar powered catamaran basks in the Greek waters preparing to assist the Terra Submersa archaeological project co-organised by the University of Geneva, the Neuchatel Latenium, the Swiss Archaeological School in Greece, Greece’s Service for Underwater Antiquities and the Greek Centre for Maritime Research. (…)

Before excavations officially begin on August 11, MS Turanor PlanetSolar has grasped the opportunity to tour the Greek waters and bask in the Greek sun. The solar boat is currently undertaking a tour, visiting the ports of Eretria, Athens and Nafplio and is open to visitors who wish to learn more about the work that archaeologists will carry out in the Argolic Gulf and the various applications of solar PV technology.”
