I was listening to the BBC on the radio and they interviewed someone from the Federation of American Scientists. The story was highlighting a building technology that stand up to hurricanes and earthquakes. Here is a link to their paper on this: http://www.fas.org/main/content.jsp?formAction=297&contentId=64

It is an interesting idea. I have heard of houses in my area that have foam insulation used to create forms for concrete.
