One acre, 209' x 209', is sufficient to supply ~1.19 homes consuming 1Kw each hour for an entire year.

Most charts give $150 @ full cord of wood (which is correct hereabouts anyway) not $115. And I've seen $1.73 @ bushel for corn, not sure about the others. I am not going to argue that point. Because you are right depending on where you live. As far as the corn, though, what is nice about that particular stove is that you can burn moldy or "junk" corn. You can also use other grains that are grown, so if corn is high in price, just go and buy the cheapest grain at the time you need to buy the grain to heat your house. Just a little more insight. :-) Jeremy ------------------------ Yahoo!
