On June 25, the world’s largest solar ship, the MS Tûranor PlanetSolar (http://www.planetsolar.org), was docked in Boston and hosted a symposium on water and climate change, “From the Alps to the Atlantic.” This 35 meter by 23 meter catamaran is currently on the DeepWater expedition, harvesting data from the Gulf Stream after a maiden voyage around the world on the equator.  From Boston she is bound for St John’s, Newfoundland, Reykjavik, Iceland and finally Bergen, Norway.  After the transatlantic DeepWater expedition, the PlanetSolar will work with the Waste Free Oceans Foundation (http://www.wastefreeoceans.eu) to clean up European waters.  The research team from University of Geneva is headed by Professor Martin Beniston and consists of climatologists, physicists, and biologists.  

The PlanetSolar has 512m2 of PV cells and the largest civilian mobile battery in the world providing 20 kW of electricity, 17kW for two 60kW electric motors,  with 3 kW for life on board, for an average speed of 5 knots and a maximum speed of 14 knots.  The PlanetSolar is a traveling experiment laboratory and sampling station working on water issues around the world with room for a crew of nine.

The symposium included talks on the global water cycle including river systems (http://www.globalrivers.org), glaciers and mountain water resources (http://www.acqwa.ch), ocean ecology, acidification, phytoplankton and zooplankton biology, and other issues.
