<s>[INST] And what's the biggest uncertainty with getting to 2030? Is it manufacturing ramping? Is it the raw materials? Is it something else? [/INST] There are some raw material constraints that we see coming. In lithium production, probably in about three years and in cathode production. Cathode, the two main cathode choices are nickel and iron phosphate. Obviously iron is extremely plentiful, but both is 32 per cent higher by composition. So, little bit of trivia if someone says what is Earth made of? The single biggest element that Earth is made of is iron. The second biggest element that Earth is made of is oxygen, which is about 30 per cent of Earth's mass. So clearly iron's not in short supply. The phosphate is slightly more of a challenge, but still quite common. So I do not see any fundamental scaling constraints and lithium is also quite common. Lithium is practically everywhere. So this is not a question of a shortage, as though some rare element it's really just that the lithium mining and especially the refining capacity, and that of the taking iron and phosphorus and turning it into battery grade iron phosphate, or nickel and turning it into battery grade nickel it's really the equipment. I think the single biggest constraint would be the equipment necessary to convert the ore into battery grade materials.

Yes, I think you're sort of putting too much emphasis on those 20 million vehicles by 2030 as though this is some grand promise, of some hill upon which we will die. It is simply an aspiration. And we may achieve it, we may not. Our goal is to accelerate the advent of sustainable energy and so that's why we want to make a lot of cars and also a lot of stationary battery packs because the three pillars of a sustainable energy future are: electric transport, stationary battery packs, and solar and wind and geothermal and hydro basically sustainable energy sources. With solar and wind, particularly are intermittent, and so you need stationary battery packs to store the energy when the sun doesn't shine. </s>
