"There's hardly any vibration, the solar panels provide us with shade and, unlike a sailing boat, we make good headway even when there's no wind," crewmember Beat von Scarpatetti said on his blog. Obviously, boats have been making this trip using no fuel for a long time, relying on wind power. In fact, the boat traveled roughly the same route that Columbus used when he first crossed the Atlantic in the 15th century.
I find it rather interesting that it took this long to progress from the first crossing of the Atlantic Ocean on wind power to finally doing it again using no fuel, this time with solar. Interesting and cool.
