I think the reason that we don't see better architecture[s] is because it’s working. It's cost effective. And we are replacing a component, which today is a commodity ... There is no ... manufacturing process today that can solve or change the architecture ... Even if you were to tell people [your technology would allow an EV to] go 1000 miles, but it will cost 2000 times more, no one would move. So, if you want to come [to market] with [a] novel architecture, you need to remember two really important things: scale -- how to make millions of batteries a day -- and at competitive costs.
