The more I learn...the more questions I have!! PAPROUD, how did you settle on the OWB that you purchased? Did you consider the gassifier in an enlcosed shed of some sort? Regarding storage systems....exactly what does "open to the atmosphere" mean? The tank has no top???? I really like the idea of a gassifier, mine would have to be 100' from the house with storage in my basement and I guess I'll need to build a small insulated enclosure for it unless I go with the "outside" type...but it seems that's really new and maybe still has some growing pains to go through?
