"chippy cheap heat"

While having a coffee at my local diner i overheard a conversation between two guy's who worked in the lumber industry, The topic was about the spontanious combustion of Wood chips were they where being stored outside a wood proccesing plant. The combustion of the piles of wood chips was caused by the improper mixing of two different types of wood chips which when stored together, caused a chemical thermal reaction between the two. The conversation dealt with the difficulty of extinguishing the slow burning piles of chips. It seems that it was next to impossible to accomplish this without a major effort which would involve taking apart the mountains of wood chips to get at the smouldering fires within. At this point i was reminded of a time i was mixing fiberglass resin and had added too much catalyst to the mix,,the result was a container of resin which began to super heat. I had tried to smother the resin in a tub of water and was shocked at the amount of energy given off by the chemical reaction of the resin. It took as i remember, about an hour before the container of resin (which i had submerged in water)cooled down enough to handle. The thought came to me in a blinding flash that; the problem these two guys where faced with was in all reality a "BOON" I began to think of a way in which these elements could be brought to-gether in a contained environment to create heat for use in making steam, and off course, heating buildings cheaply. I am of course typing this as i'm thinking on the posibillities, so forgive me if i do not have all my ducks in a row yet. My intention is to begin a dialogue and see where this leads, as i am fairly certain there is some value to this idea. Anyone???????
