Pretty looking ship. Of course we have had beautiful, solar powered (via wind) ships for a long time. The clipper ships were perhaps the height of this technology, but were superceded by steam ships. I suspect that this technology, while pretty, is a dead end for ships. Ships are like any other capital equipment - speed and rapid turnaround reduces per shipment prices and is therefore the driver for ship propulsion and design. Solar energy, whether direct PV conversion, or the more energy dense wind, is just not energy dense enough compared to fuels. It seems far more likely that "solar" ships will use solar energy produced bio-fuels as the development path.
