The one thing I would say, as the member's brandishing his iPhone, is that Apple—and this is a point that I am repeating—have entered into a US$2 billion agreement with another aluminium producer to do hydrogen-based, zero emission aluminium smelting, and that makes our smelter completely uncompetitive. So what we want to do in an ideal world is onshore that technology to our smelter here in New Zealand, but we won't do that as long as there's absolutely no incentive for them to do so. We're really keen to work with them to get our hands on that technology and to bring it in, just as we are for some of the emerging—steel's probably about another five, 10 years behind where aluminium is, but we're quite keen to see some of what a new hydrogen-based steel production is like for our steel mill for the same reasons.
