Ernie and Paul. From what I can tell, you guys know the most. I wish I was alot closer, so I could learn directly from your expertise. I have recently become self aware of my enviornmental impact, and I am dicussted with myself. I've been recycling and planning shopping trips to reduce my impact, but my use of fuel to heat my home is crazy. So I began a quest to find alternatives, which lead me here. The problem is , I can't find any one plan, that says "here is the tried and true measurements". I've spent alot of time over the last 2 weeks looking. I'm sure I've overlooked it somewhere. I'm also dealing with a space issue, but I really want a RMH because I can get lots of free fuel ( broken pallet slats from my job). But, the space thing...... I was wondering what you think about the possiblity of a verticle mass section? Zig-zagging back and forth, but on an incline and going up with each zig and zag. Make sense? Hope so, because my drawing skills are really bad. Thanks For Yor Time.
