Get a load of this: The spaceship-looking solar-powered boat-which we told you about when it was still in its planning stage-is basically done, and after a little more safety testing, the thing is going to travel around the world powered only by the sun.PlanetSolar unveiled it yesterday. Its specs: It's 102 feet long, 50 feet wide, cost about $27 million to make, and is expected to reach a top speed of 15 knots. Which is... 17.3 miles per hour. (Here's hoping the guys aboard like each other, because at that speed, a trip around the world will take a minute.)Here's the course they're plotted:I might be tempted dismiss as an expensive novelty project if it weren't for the fact that the scientists have promised to share everything they learn about how well the technology works, what glitches they encounter, and all other kinds of data collected en route.
