#11 "Plastic Brick Maker"

#11 "Plastic Brick Maker" using the same tech assumption as in #10, I'd like a device that melts plastic bags down briefly for molding into a plastic brick. This brick would be a simple building tool, perhaps for the developing world. Perhaps it would have to use the loom technique as well, weaving the plastic bag into itself strongly enough to form a tight brick-shaped thing. Honestly, most any idea that re-uses the millions of plastic bags that float around the world right now would be excellent. Until we're smart enough to use and reuse sturdier grocery bags, we have to find a way to pull the plastic ones back out of the waste stream (at least for a bit).
