Fire from the moonlight

http://what-if.xkcd.com/145/

Actually, I think you can make fire from the moonlight -- it just won't be easy. All you need is square inch (or so) of mirrors on moon. If there was not enough of mirros on moon hundred years ago, I'm pretty sure we put enough junk there in last 100 years.. probably including some mirrors for distance measurement.
