I've seen inexpensive homes built from things such as old tires to glass bottles before and I always thought hmm, clever.
Building from scrap aluminum is also clever, I suppose, but I would hate to hazard a guess as to what it cost to buy that at scrap cost and then helicopter it up there. Also, it may ok work in a dry climate, but I wonder if there would be corrosion issues in a wetter area. And what about cold and heat? Aluminum is a very good conductor, as I've noticed from working on semi tractors.
