Rematch: Archimedes Death Ray

A week or so back, we linked to reports of MIT trying to outdo the Mythbusters by "proving" that the story of Archimedes death ray (i.e. Archimedes using a giant mirror to fry Roman ships with sunlight) was possible. Well, the Mythbusters decided that perhaps MIT was getting a little big for its britches, and invited the team to try and do their trick again on an actual fishing boat (i.e. as opposed to a small model the MIT team had used originally). Well, apparently under "real-world conditions" they couldn't replicate their success. And apparently this was on a sunny, clear day in San Francisco... should have been ideal conditions.
