When I was in grad. school I remember reading about a guy in Colorado who had successfully heated his house for an entire winter by using nothing but junk mail as fuel. Obviously his heating system was upgraded for maximum efficiency, but it's still something to think about. He'd gotten himself on as many direct mailing lists as possible. I'll see if I can find it on the net somewhere and post a link if I can. Forget what journal it was in.
