Earth-Ships

Here we will collect and refine all of humankind’s experience and knowledge about these amazing earth-ships.. So at some point we can provide a really good “how-to-build-an-earth-ship-guide” for everyone – for free!   Please post videos and ask (and answer) questions like: What are the actual costs? What materials are being used and where to get them?   And of course post your own reports here, once you built an earth-ship yourself!
