Cool idea, but very quickly you will realize how inefficient wood is. Even turning that wood into charcoal would be much better. Just to give you an idea and I hope my math isn't that far off. It takes about 8500 coal to keep a boiler running for 24 hours. Wood planks might be a 1/4 of the burn time as charcoal, which means you will be pumping 38k planks into that thing a day... Just saying... If my math is off someone will correct it I am sure.
