haha, I have just seen a 1 hour video about Earthships and I was amazed how awesome they look. Not to mention how useful they are. In the video they had everything, water filtration which allowed them to use their water 4 times for different things such as showering, watering their plants (which also provided them with food) flushing the toilet and for gardening. What surprised me the most was that those houses didn't look bad at all. If someone would have told me: Yeah I live in a house build from trash and car tires I would've never imagined such beautiful homes. Truly great idea and encouraged me to try this stuff out myself at some point.
