Apparently, in 1968, the founder of Heineken's grandson, Alfred Heineken came up with an idea to make heineken bottles square so that they could be used to make buildings with.
He was visiting the caribbean and came across that famous green glass but he couldn't go fifteen feet without seeing it littered everywhere. He realized that the region did not have the infrastructure to re-use the bottles like other less impoverish areas so he came up with a solution: a brick that holds beer! Viola!:
It even has the little notches on the side to make it easy to hold together with mortar or what not.
Sadly, this bottle never got to the market and the closest thing to it that has been talked about more recently is this little heineken cube, but it is more for saving space than anything functional.
I apologize for the stupid question, but every time I see a picture of a building like this I wonder what the other side of the wall looks like. I think these sort of buildings are beautiful and I would love to build one. Is the open ends of the bottles on the other side just open or are two bottles fitted together? How does it work?
