I like the idea Scott gives about giving a outside air "Choice" for the feed. I never gathered from Scott that he suggested anything other than the standard intake feed location (stjohn) and I think Scott isn't suggesting to cut off all air from inside, but only to allow outside air to enter the room close to the feed location. If the Feed is pulling air from inside the house and originating from every crack and crevice anyway, then introducing a duct opening to the inside house air, would allow the feed to choose where it gets the air from, and where the air pressure equalizing occurred. IMO, this doesn't require figuring in the length of that intake duct, otherwise you may have to figure in the length from every crack, since the air has to enter the house somehow. I wonder what an air pressure meter would read in a house that doesn't offer a direct air from outside? (What meter would read that?) If you could measure air pressure changes inside a well sealed house, seems like either the air pressure would be reduced if the house was sealed really well, or air would enter through cracks to equalize it. To clarify, I am just a newby in the RMH arena, though have 54 years of thinking mechanically, and reasoning everything out to a mechanical solution, which didn't come with the means of clearly portraying it to words, lol. Sorry if it sounds muddled, I found this subject very interesting.

I Am guilty, I had just unloaded my 3500 Lbs of fire brick, and had about an hour to kill before work, so I slapped it together, without measuring. I promise the next test will be close to 28 to 30 cu" dimensions. I finally found a vein of clay in a cut out along hwy 95 on my way to Lewiston. Here's a sample of the clay ore I got yesterday.

First post to Permies, got to say I have learned so much since happening upon the RMH on the internet. I picked up fire brick for 50 cents each, and drove my prius and trailer 100 miles to get it. Way over loaded, but it is used to it, at 220,000 miles, I've been testing loads since it had 50,000 miles. Anyway I now have a good selection of brick. Still reading Ianto's book, and looking over ernie and erica's as builts. Plenty of reading to do, but got my first test up today and fired it. It did well for a first try and dry stacked brick. I have clayish soil in my field, but still trying to process some samples. It dries white, I suspect it has too much dirt in it. Anyway, I don't have much to ask at this point, but figure I could post some pics, and begin my story.
