PlanetSolar, the world’s largest solar-powered boat, is scheduled to finish its first around-the-world journey this May 4th, 2012 in Monaco. Hercule harbor will welcome the boat, which has been travelling around the world to promote solar power since September 2010.

Raphaël Domjan, the project founder, will tell stories about some of the highlights of the ship’s adventures during a weekend-long party in Monaco. “Part of the party, such as the ‘SolarLightShow’ or the concert of the Swiss band Sonalp, will be powered by the energy of the boat’s batteries collected during more than 19 months of sunny navigation,” the Planetsolar website states.

In total, the MS Tûranor PlanetSolar will have sailed nearly 60,000 kilometers by the end of its journey, all powered by the sun.
