Great Stuff-- I'm in.
I note the implied goals of enticing "soccer moms" and other suburbanites toward adoption-- the included cost savings comparison with natural gas for example. But I'm wondering since very few have shown a clear pathway toward navigating logistics of building codes, redesign/reuse issues of existing (forced air, electric baseboard, etc) heating systems will this actually be appealing to those NOT ALREADY pursuing (homestead) new construction? I understand enticing those who already use wood/pellet stoves for heat, but the implied natural gas substitution seems quite a jump.
I've heard a podcast with Erica describing new construction compliance issues in the Pacific Northwestern states, but until that process is neatly delineated in a way that invites exploring one's own local legal landscape I doubt many will get past the "wow" stage even after they literally warm up to the idea of an oil drum in the room. I would suggest maybe a future DVD: "Here's how to make it happen in YOUR home..." (nut just for tipis in the woods)
In any case I realize this tech is new and I eagerly await the DVDs which I will lend to friends at every chance.
