I found this interesting and wanted to share it.


Using solar power only, the catamaran "sun21" is undertaking the first motorized crossing of the Atlantic with solar power to promote the great potential of this technology for ocean navigation. The "sun21" is due to arrive on 8 May 2007, 3 pm, in New York, having covered about 7000 sea miles.

Arrived. http://www.transatlantic21.org/
In 1986 we went cruising for a few years. After 20 years and 50+ countries and several oceans, we are STILL "cruising for a few years".

I found something interesting, in the FAQ Link at:


The intersting thing is "solar-hydrogen", which may relate to the current topic of "Fuel Cell" technology.

Why is "sun21" not going to circumnavigate the world?

In theory, this would be possible Ė without one drop of gasoline "sun21" could travel on for several years. Of course, the boat is rather slow and a trip right round the world would take quite some time. Furthermore, the boat is not equipped for all global oceans. MW-Line, however, together with the PlanetSolar team, have already started to plan a first circumnavigation with a solar-hydrogen boat. The experience with transatlantic21 will feed into this new project.
When in doubt, do the right thing.
