Does anyone know of some good alternative architechtural concepts that are sustainable and environmentally friendly?  A couple that I am familiar with are Earthships and Formworks.  Earthships are a form of earth berm sheltered rammed earth construction that utilizes the over abundance of used automobile tires as building blocks to contain the rammed earth.  Formworks are thin shelled concrete domes that are covered by earth.  Both look really nice and have a sound philosophy behind them.
