Dr. Geiger has been involved from early on. Everytime I would vary away from the original concept he would be on to me to get back on track. He shares the vision of a manual system that can be used by the semi-skilled under the worst of conditions to create shelter and industry. Dr. Geiger is now in Thailand working with locals who make CEB’s (compressed earth blocks). http://www.motherearthnews.com/Green-Homes-Expert-Owen-Geiger.aspx
