Just out of curiosity has anyone ever sat down with a meter and figured out what folding costs you in electricty. I shut down a server I ran 24/7 for years (and replaced it with a HP WHS) and realized a $20/month decrease in my electric bill. That server wasn't really doing all that much. It hosted some web sites that no one visted and ran an email server that serviced one user. I imagine had that thing been folding with all its unused cycles (which were many) it would have been much more than $20.
