According to the designer, the solar-powered Arkki is the kind of boat you would like to have in case the ice caps melt. He's wrong. It's the kind of boat I would like to have right now.
Apparently designed by Cylons, the trimaran's surface is covered with multilayered solar panels, which power the ship and can bring her up to 8 knots. The hull is made of concrete and reinforced with plastic fibers.
What I like most about Arkki is that it is designed to be a house. And a very large one at that: It has 1647 feet of interior space and a 1076-foot exterior wood deck. It's not as big as the WHY, but it looks much better. So good, in fact, that Sean Connery would like to use it if he were playing Noah in a movie.* [Janne Leppänen via Tuvie via Bornrich]
