Paul sits down with Davin Hoyt who has listened to every single one of the podcasts. He mentions how if anyone listens to all the podcasts, they can make a list of questions (that cover stuff not in the previous podcasts), and he will sit down with you and answer those questions in a new podcast.

Paul starts out by talking about the wheelie bin poopers and the evolution of their titles. He says that the title he prefers right now is “The Willow Bank”. This comes from the idea that the soil that comes from the poop from the pooper will feed willows or cottonwoods. Paul get into how the stuff coming out of your butt isn’t waste, and how we need to optimize systems to re-use it.

Jocelyn chimes in by noting that the poopers are not outhouses and they’re not composting toilets, just for any of the pod people who weren’t aware of that. The poop goes into a bin and the bin is closed for 2 years. It then gets opened and that soil will be put at the bottom of willow tree.

They continue to talk much more about the poopers they have at the labs and how they’ve evolved, and how they all think they could be improved. Then they move into talking about the pee palace and how to optimize it for women.

Next they get into Davin’s questions. His first one was: Where do gappers stay? The answer is essentially: one of the many different locations at the lab and base camp. Sometimes there will be gappers that come to help the ants at ant village, and there are gobs of places to pitch a tent there. Then they move into talking about money and the fees associated with that.

In the last part of this first section, Davin asks about Wofati Stuff. Even though there was lots of talk about them, there were still things he didn’t understand. His first question is about annualized thermal inertia. Specifically, about the placement of the masses that give off the temperatures that allow for thermal inertia. They talk about Allerton Abbey (the first wofati) and the large masses on the left and right, behind the wing walls. Paul discusses how to test how well the thermal inertia works. Lastly, they talk about Mike Oehler and all of his philosophies and the deal with visiting him.

paul: "we're gonna store the heat through the summer, so we can heat the home in the winter"

ok so I had struggled with the idea of the 'ati' in wofati until this podcast. suddenly it clicked. you are like seriously using the earth integrating as a heat battery that the house is using and charging with the seasons just because of how heat naturally acts.

cold isn't actually cold, it is lack of heat. you have heat and lack-of-heat. heat moves around. lack-of-heat happens because heat is moving away from it for various reasons.

in summer the earth integration is sucking up heat. its sucking it from outside and from inside the building. heat is moving from in the house to into the earth integration and causing lack-of-heat inside. thus you are charging the 'battery'.

in winter the earth integration is using the heat, draining the charge. its sucking the heat from the earth integration into the building. the air is sucking the heat from it into the building.

I am not hugely into the science of how this works but thought I should share my light-bulb-moment here for others who might also not understand it fully.

If I remember correctly, the pattern language is that a room needs to let in natural light from two sides.
In normal construction, this tends to mean putting windows in all four sides of the structure.
In less normal construction, something similar could be achieved by having windows on two (or three) sides
and using windows inside to allow the light to pass through.

Indeed. The Pattern Language calls for light on two sides.

I still appreciate Mike's insistence on getting so much light into an "underground" house, although I'm not convinced that the angle of the window is as important as he makes it seem. Light "separation" seems more important, (like audio stereo separation). For example, in a big room if one side is mostly windows, and then at the corner you turn 90 degrees and squeeze one window perpendicular, but adjacent to the large wall of windows, the light is still essentially coming from the same direction if you're sitting in the middle. I would rather have light coming from two opposite sides of a room, than 3 sides, all in one general direction from the center.
