There is a website that has some interesting publications on it mostly dealing with health, Sustainability and Freedom: Kaceper Postawski Companies. A couple articles I found interesting were Dealing with Banksters free yourself from bank related debt, and what brought me to the site in the first places BioDome Structures.
Rain water recovery: This company has some interesting products. I have not done business with them but I am putting them up here for information purposes. http://www.rgjinternationalsa.com/rainwater/homegardenkit1.html
Turtle Tuff Survival Shelters, although not a bio dome per se, I find this shelter system interesting.
Shelter Systems looks like it has a good design for dome shelters.
Here are some You Tube Videos on Biodomes:
