Chris,
Thank you for your thoughts. Here is some additional rambling from me...
I'm active duty military and I have a great appreciation for when someone provides me with a holistic solution to a problem.
That is why I think the earthship appeals to me so much. At least, they address some of the big things I'm concerned with. Comfort, power, water, sewage, food.
I understand building code is/can be a huge issue. So I know I have a lot of research ahead of me.
Now, what I have yet to read is if some of the other solutions employed are as "good as advertised." For example the grey/black water processing solution.
Does it actually work as well as designed/advertised? I sure hope it does. It looks amazing.
My young nephew plans to do his science fair project this year on Earthships. I can't wait to see what he comes up with.
Chris
