Well, the results came in a while ago, but I forgot to mention that [I lost](http://diaryofnumbers.blogspot.com/2010/05/we-have-winner.html) the contest. I was about two orders of magnitude off from the winning answer. In light of my failure, I'm going to try again in the [newest contest](http://diaryofnumbers.blogspot.com/2010/05/hamster-powered-mansions.html). This time the question is a bit stranger: > How many buff hamsters would it take to completely power a mansion? I encourage all of The Virtuosi readers to enter as well, it only takes a minute to come up with some number. Good luck one and all.
