I stopped at Sawdust Supply in Seattle to pick up the whopping 8.5 lb presto logs that Thomas provided for the next round of tests(coming soon!). Really nice folks. The company used to be in the business of selling sawdust as fuel. They still had customers up until the last decade that had basement sawdust stoves. It's no longer practical, mainly do to the poorer quality of sawdust that now comes from the mills. Old growth fir sawdust was much drier and had higher pitch content which made a great fuel. One would get it pumped into the basement bin from the truck, just like coal. Then a couple shovels full in the morning off the top of the pile would set you for the day. In their heyday they had a lot of customers heating with these stoves and they allegedly burned relatively clean.
Here's a link or two I found. The first is an article that found some still being used in Chile and Afghanistan. Even shows how to build one out of an oil drum Bart! With Eric's or earthharvester's operations, maybe you are overlooking a heating source? Should make a great greenhouse heater.
