The Promise

IBC totes in a crawlspace of SEH 2000 with a 12kW PV system and a $6000 off the shelf heat pump get us to full winter and summer heating/cooling with storage for 20 days if sun doesn't shine. Buffett Jones loved this when I told him this evolution, we should be able to implement this in one of our next 10 builds while coming out at a $100k SEH 2000 materials cost. Zero CO2 because it's PV power. Details at IBC Tote#Calculations, where cost is $9.5k for a 25 tote (5 day) system.
