I worried about the exact thing you are suggesting.  When I was on my way to see the oehler house in person, I thought it would smell musty due to the damp.   But it was not musty.  

The two wofatis on my property have both been very comfortably cool in the worst heat of the summer and there has never been an issue with damp.

Here is a tour of the original oehler strucuture when it was 40 years old

Part of the wofati design is based on an oehler structure.

I go into a lot of detail in my new book.    But the general idea is that there is a membrane extending 20 feet from the house in all directions.  In a way, the house is under an umbrella along with hundreds of tons of dirt.  This dirt acts as an insulative barrier AND holds heat on an annual scale.  The first real experiment begins next summer as we charge the mass.  This winter we hope to do indicative tests.

Well, mud and logs.  And a bit of straw bale.  Most of the materials came off the land where it is built.



A house the sequesters tons of carbon.   Zero paint, glue or cement. The heat from the summer heats the house through the winter.

We didn't add any coloring to any of this.   This is the color it is when we pull it out of the ground nearby.

There's a whole lotta people at my place. And all of us are keen on natural building. At the same time, we do lots and lots of experiments.

Here's a new video about some of our experiments with cob floors. For those that are not familiar with what cob is, it is a mix of sand, clay and sometimes straw. I am fortunate that my property happens to have several types of clay and several types of sand. So we just dig it up and make cob stuff.

So here's a short video featuring some progress on some floor experiments.

A fence made of waste wood (this wood is typically burned in
an effort to reduce wildfires).  It's a bit like making fence out
of bamboo, but in an area where these conifer poles are considered a
nuisance.  You can see the rock jacks (this particular property is one
giant rock) - but ignore those for this video (we hope to have a rock
jack video later).  Pretend these are normal fence posts.   This
particular fence is being made 8 feet tall to keep deer out and to
keep layers (egg laying breeds of chickens) in.   This is a BB for
part of the sand badge for woodland care in the PEP curriculum. You
start by installing two horizontal poles along the top and bottom on
the same side of your posts. Then you install four evenly spaced
vertical spacers on the outside of the fence rails. Once you have your
spacers up, you install one more horizontal pole across the middle on
the outside of your spacers, and then you can just drop in loose poles
to fill the rest of the fence up. Voila! Easy fence made reusing waste
wood.



The carbon is now in a fence instead of up in the air.  Cheap, quick and easy.

Building good things rather than being angry at bad guys.

This isn't a technical book. But it's written by Paul so it deserves a thread here.

Summary
From the Introduction,
"For nearly every global problem, there are solutions we can implement in our backyard that also save us money and help us live more luxuriant lives. A few of us do these things and bask in the glow of the opulence and extra cash. Others observe and think “I want extra luxury and money too! Not fair!” and then they emulate. And on and on it goes. Then the global problems sorta just dry up and blow away. That’s what this book is all about.

I think the reason we see so many people angry is because they authentically care. But they seem to get stuck at being angry. Some people spend a hundred hours a week for 20 years being angry and not much changes. But I think that if you spend a tiny fraction of that time doing the things mentioned in this book, your global positive impact will be a thousand times greater. ."

About the Authors
"Paul Wheaton is a giant doofus who is bonkers about permaculture. He won’t shut up about permaculture. On and on, every day . . . it’s annoying. He has gone so far as to make a 3-DVD set that is just about the earthworks for permaculture gardening. And not only did he make a 4-DVD set about rocket mass heaters, but he made ANOTHER 4-DVD set about rocket mass heaters. Why on earth do people need 8 DVDs about something so simple? If you think that is ridiculous, take a look at his 177 hours of video of a full Permaculture Design Course, and Appropriate Technology course. Then there’s the cards. Okay, the permaculture playing cards are pretty cool...

Shawn Klassen-Koop’s passion for building a better world grew from many years of working at a summer camp. This time inspired awe and wonder for the natural world through many hours camping in the woods, paddling on a lake, or sleeping under the stars. Seeking to solve world problems with clever thinking, Shawn decided to pursue computer engineering as a career, where he learned the importance of good design and strong critical thinking. In time he felt like modern technology was causing more problems than it was solving and started looking for a better way. "

As far as I know it is still going on.  Did you write to the nitpicker email address?

Tony,

I have alerted the book promo peeps.   If you don't get an excellent answer in the next 48 hours, reply to this email and I'll see what else I can figure out.
