Here’s an interesting presentation by the same folks who designed and built the earthship greenhouse in Montreal that I featured in yesterday’s blog post. The speaker makes lots of good, thought provoking points. It sounds like they’ve moved beyond earthship greenhouses and are now working on modular sustainable housing for cities. Their new designs are faster to build than conventional houses and very energy efficient, however the cost works out about the same.
