SUCCESS!! IT WORKED!! I bought a small air conditioner for $100 (with a remote- very neat, and supposedly it's only $35/year to run it) and my boyfriend put it in the window and we cranked it up. With it blowing on the back of the tank all night, I woke up this morning and the tank went from 74 to 69 degrees- yae!! I was told not to put a tank in front of a window, but I did it anyway because I had no other good place. Now, that decision has saved me a lot of money. From now on, I will always put tanks in front of windows I think....But man that room is COLD!!! I do a lot of artwork in there, and I'll be working in sweaters and socks for sure-ha!!
