Apropos: A few years ago, I went to a remote resort (in India) for a vacation. It was in a forested mountainous area. A few km. from the resort, there was an earthship. It had been built over a period by a British guy who lived in it. Rather large. Like a cylinder capped with a roof. Lots of glass to let in sunlight. Partly self-sufficient, for water, electricity via solar, heating via the glass windows, etc. (it was in a cold place). It was at the edge of a high cliff with a direct line-of-sight view to the plains. He had even set up some kind of way to catch the Internet signal from the plains and supplied it to the rooms of the resort for a fee. He was also a remote web developer. Rather cool.
