One of our fellow eco-enthusiasts alerted us about a great idea in eco-friendly building materials:  glass bottles!  We came across this breathtaking million glass bottle temple in Surin province, Thailand called Wat Lan Khuat which has been built entirely out of empty Heineken and Chang beer bottles (Heineken giving the green color, Chang the brown) and concrete.  Mr. Heineken himself wanted to develop bottles shaped like bricks to aid in this usage (pictured above right) back in the day but gave up on the venture.  Others though have taken this inspiration and created beautiful, bright and eco-friendly bottle walls all over the world.
