They look very similar to the Hamech boilers ( http://www.newhorizoncorp.com/offer.php?id=17). When I looked into them it seemed as though there was just too much moisture in the pits for it to work.
I could get a grain dryer to dry down the pits, but I would prefer the simplicity of burning the fuel wet.
