Photos or Videos of Mike Oehlers PSP Construction?

I'm posting in hopes to learn more about the Mike Oehler PSP formula for building underground houses in Appalachia.

I've looked through an older copy of his book from a local library, but I feel like I am missing some information just reading the book. I want to get my hands dirty by building a small version that might be 10 by 10 feet. Maybe I'll hit a few walls, but I'd like to try it.
My goal is to learn enough so that when we build a larger version we won't make any serious mistakes.

So I am reading his books and going through his workshop videos. One trouble that I am having, however, is being able to visualize some of the designs. Specifically the initial PSP structure and how these would be built into the floor polyethylene, how the walls would be built up, and perhaps most importantly how exactly to notch the posts and set the roof. I know that if they are in the wrong direction it would enable the earth to cause the whole structure to lean… I know that many of these things are in the book, but I am coming here to see if anyone has photographs of construction in progress following the PSP method or even videos? Especially the minute parts of the construction and details.

Thanks for reading!

I find Mike Oehler's work to be very interesting. Here is a thread I've started in my search for more information as well:

I believe there is a lot of potential, but I'm trying to figure out some more of the construction minutia. It would be nice if there were an "heir" to his efforts that could share more of the details from both the construction and history of these houses over time.

Mike's book and videos explain all those things.

WOFATI maybe not the heir, but the illegitimate son.  Lol

I do have concerns about transferring the technology to inappropriate areas.  There have been places I've lived that built modern house foundations out of wood (pressure treated ply and 2x) that were mortgage approved, and areas that ANY wood would rot outside (not even in the ground) and they only used wood in air conditioned spaces.  I am pretty sure southern Appalachia would have drainage and rot issues of the site is anything less than ideal.

They do explain much of the process, but some areas remain sort of foggy. Perhaps I will just have to derive what I can from intuition, or the "great potato" as mike calls it. But seeing a picture or video of some of these details would really help in construction, especially the small but important details such as the post and floor polyethylene interaction, notches, etc.

Here's a simple pic showing some of the notches I've made.
The idea is to use simple tenon & mortice joints where possible.
