RE:RE:RE:RE:Bernard clearly stated 4N is base minimum but aiming for 5N+The Vertical component of this is insane i agree a buyout way before we get to a commercial unit. The big silicon manufacturers are not going to want the likes of boeing, Tesla, mercedes, the list goes on and on supplying their own silicon battery powders as well as the silicon needed to make their car frames dont forget Si goes into the aluminum for strength. They would buy it out pretty quick to prevent proliferation and it cutting into their profits plain and simple....the question is how do you put a dollar figure on that?
