World's largest solar-powered boat sailing under the Swiss flag
CIRCUMNAVIGATING the globe using only solar power is the highly ambitious goal of the PlanetSolar project. Sailing under the Swiss flag, the largest solar-powered boat in the world, PlanetSolar completed the first trip around the world powered exclusively by solar energy.
A technological masterpiece PlanetSolar really is an
amazing feat of technology, designed and developed by a diverse team of physicists, engineers, boat builders and environmental consultants. At 31 metres long and 15 metres wide, the carbon-fibre catamaran weighs 85 tonnes and can reach an average speed of some 7.5 knots (15 km/h). The energy to power the PlanetSolar comes from 536 square metres of photovoltaic panels, making it the biggest solar boat in the world. Even as the sun sets, she can continue to sail through the night thanks to the surplus energy stored in her ion lithium batteries.
On 27 September, 2010, on the shores of the Mediterranean and sailing under the Swiss flag, PlanetSolar embarked on a voyage to circumnavigate the world. To benefit from as much sunshine as possible, the boat navigated 50,000 kilometres along the Equator, taking in the East and West Coasts of North America, Australia, Singapore and the United Arab Emirates along the way. In May 2012, it completed the journey around the world.
The journey ahead The largest solar boat ever built is now sailing with the objective of demonstrating her practical application. While 2012 was a historic year that proved that a trip around the world powered exclusively by solar energy was achievable, 2013 will demonstrate the solar ship's practical applications and potential. Since May 2013, PlanetSolar hasbecome a scientific platform as part of the "PlanetSolar DeepWater" expedition. This project, led by professor and climatologist Martin Beniston from the University of Geneva (UNIGE), aims to harvest new data along the Gulf Stream. Due to the MS Tfiranor PlanetSolar's special features, the measurements collected by the onboard scientific team will not be distorted
by pollutant gases, an important factor that should enable clear identification of certain components of the ocean current.
In summer 2013, the ship will continue her itinerary by taking part in a campaign to clean up European waters, a project initiated by the Waste Free Oceans Foundation which took on a mission to significantly reduce the floating litter in European waters by 2020. The MS Turanor PlanetSolar will be equipped with an ingenious trawling net—a sort of giant filtering scoop—that can collect up to 8 tons of marine pollution
Sustainable development
Following on from the Catamaran sun21 (Atlantic crossing in 2007) and Bertrand Piccard's Solar Impulse glider, the
PlanetSolar project once again confirms Switzerland's status as a leading innovator when it comes to sustainable technologies. The vision of a solar-powered catamaran was driven by a desire to demonstrate the effectiveness and safety of renewable energies, particularly solar power and its related technologies.
The architects of the project hope that their initiative will boost investment in research on clean energies and ultimately revolutionize marine engine design. This is no mean feat, when you consider that 90% of goods are currently transported by sea in huge freighters that guzzle vast quantities of fossil fuels and are major emitters of greenhouse gases. A further aim of the project is raise public awareness of the potential that these energies offer.
