Maybe I can use the next couple of days to ask a few questions of my own. One thing that has been troubling me is that during full flower, when everything is humming away, the main breaker can trip. Well, not exactly "trip", but half of the panel will die, even though the main switch hasn't flipped. When I turn off main, and then on again, the dead half of the panel will be fine again. It's troubling, since my whole house is only pushing 70 amps, and I should have 120 amp service.
My diagnosis is a faulty main breaker. Ha! However, the panel is from the late 60's, and I don't know how to buy a replacement main without gutting and replacing the entire panel. I tried McMasterCarr, but I couldn't find anything. Any suggestions?
dude if you ever have to sell the place just let to prospective buyers the house has a custom built root cellar

Sounds like you have an unbalanced load. The panel has 2 poles A & B for simplicity you are probably have to many amps on one pole more than the other. The best way to check is get a multimeter with a clamp on amp meter check the main wires or bus coming to each side of the breaker while it is under full load and find out. If the meter shows more than 80% of the breakers ampacity on one of the poles most likely. You can sometimes move circuits around in the panel to balance the load across the 2 poles. Depends on the situation.
ICF has got to be more expensive, but in a time-is-money world... I couldn't tell from the video if the core was filled, or if it's hollow. Were those the forms, or was that the final exterior? That didn't look so painful though.
EDIT- reading through the comments on that video makes it a little more clear. Is the concrete pumped into the forms? It almost looks too easy to be true. Well, in all, it wasn't a huge structure, and it didn't take very long to block out. I think I had it the blocks laid and filled in less than a week. The slabs were the beasts, each taking me about a week to complete.
The concrete is pumped into the forms several inches thick. You can paint a water proofing material on the exterior. The structures are truly bullet proof. Google "insulated concrete form hurricane Katrina" and you will see pictures of 1 icf house surrounded by a flattened neighborhood. I haven't researched it but the chases for the wiring are inside the form. I've read for an entire house you are looking at a 4-8% premium to stick construction for an incredibly strong super insulated home.
Really inspiring stuff CBM, you're probably spawning ideas in a few heads with this information. That concrete shoot is intense and really gives a good idea of the effort that must've gone into shimmying the slurry into the bunker. Eagerly awaiting more pictures, but your stories are good too. I think there are a few of us around here that gave up the corp. life for a shot at the green dream - keep up the good work, you done us proud.
