I don't think you got my point: I think, with (essentially) a giant hinge down either side, despite how much stronger whatever alloy is going to be, the container may not be as structurally stable as the current design.<p>The current design is built entirely for longevity and strength--this new one seems to eschew that to me.<p>That's not saying it isn't a good idea though. There is definitely a scope for improvement on the current design, and this might be a good start.
