Right if you had enough mirrors. I was talking about Hellfire's idea about making a complicated sighting arrangement...
Quote:...make flat mirrorlike shields, with a small hole, about the size of a quarter, in the upper part of the mirror, then extend a pipe, weld on a BB, like a shot gun sight...
It is a piece of cake to hit an ship/airplane with the reflected spot of a mirror using the "hole" method. That is what a signaling mirror is for!
Using flat mirrors, the temperature that you'll be able to hit is basically a function of the number of mirrors you have. Unless you can bend/focus the reflector, the size of the mirror affects the size of the spot.
