We already build ICF homes (Insulated Concrete Forms) and we are working are way to building all of our homes at zero energy or close to it. We don't have to keep paying high utilities,gas (does everybody know how much profit these gas companies make each year) let's just say it's in the BILLIONS. I am dedicated to reach this goal and the more people I can help on the way the better. Please send feedback or questions stay tuned and God bless us all. Steve
