Everything you ever wanted to know about Earthships (video)

As you've seen from a post earlier this week in the Green Community, Florida is getting its first Earthship. But what exactly goes into making an Earthship and what makes it so energy efficient and eco-friendly?

Not only do Earthships utilize solar and wind energy (for heating, cooling, and electricity), they are made completely of natural and recycled items and are built to harvest their own water, have contained sewage treatment, and their own built-in gardens so inhabitants can harvest their own food.
