These homes all though are not temporary as the MICA homes, I still found them fitting because they are cost effective and completely self sustaining. Research for them is being done in New Mexico. All the houses amenities are completely self sustained, the heating and cooling, the water, food, and water are all powered by none other than mother earth. Even the materials used to build the homes are all resources found in nature, without giving up an modern day luxury like electricity or heating and AC, and especially plumbing. Not quite exactly like the temporary structure, but it certainly helps you lead a healthier more economical life, along with severely reducing your carbon footprint. Good for the environment and you!
