bottle brick construction
First Kelly Hart, at the earth bag building blog, posts a link to the bottle brick house in Africa. Then I found a BBC report on it. Eventually I ended up at Eco-Tec Soluciones Ambientales, which I think is the Latin American nexus of this technology. This video seems to explain how it started way back in 2000. My brain is exploding with excitement especially about applying this to Haiti, which has an abundance of trash water bottles all over Port-au-Prince.
