I am interested in green architecture and study EarthShips and 70's passive solar homes. Like David Wright AIA. See the book "Design for a Limited Planet", such cool architecture :
what the world really needs is open source, free plans for these types of machines. I have seen these types of machines for years, and plans cost at least $50, built machines are over $1,000, just for the machine.
There is a man in the village that has one, though it doesn't do interlocking, just plain bricks. I may take it apart and document it.
