Lets talk about Archimedes Death Ray.

“Archimedes who created a mirror with an adjustable focal length (or more likely, a series of mirrors focused on a common point) to focus sunlight on ships of the Roman fleet as they invaded Syracuse, setting them on fire.”

Turns out, it is one of the awesomestest [sic] things to try with light and mirrors.

MIT did it, read it, it’s awesome. :D
