I put this under Lifestyle, but really it could go under a number of forums.

Has anyone heard of this?

In a nutshell - sustainable living.

From the Website
An Earthship is a radically sustainable home made of recycled materials.

* Electricity is from the sun with solar panels and wind with wind modules.
* Water is caught on the roof from rain and snow melt.
* Sewage is treated on site in interior and external botanical planters.
* Heating and Cooling is from the sun and the earth.
* Food is grown inside and outside.

Earthships are constructed with recycled materials and perform as expected in any part of the world, in any climate and still provide you with what you need to survive.
It looks awesome.
Hubby and I are seriously looking into doing this when we build our own house.
There are some great looking homes on the site.

How great would it be to grow your own food inside your house ?
