Earthship Biotecture designs and builds homes that…
Heat and cool themselves naturally via solar/thermal dynamics…
Collect their own power from the sun and wind…
Harvest their own water from rain and snow melt…
Contain and treat their own sewage on site…
Produce a significant amount of food…
And are constructed using largely the byproducts of modern society;
like cans, bottles and tires.
Earthfamilyalpha has more. This is both visionary and highly practical stuff. Some of their homes are off the grid completely.
