Great post! I built an aircrete domehome with Hajjar from DomeGaia and other students last year in Mexico and it was such an amazing experience. Once you work with aircrete it will blow your mind! I also met Alosha their and he is doing some great work as well on building dome homes, water collection / recycling.
