I’d agree with the environmentally friendly, doesn’t catch fire bits. But what’s the advantage of a delivering the full amount of 10kWh over delivering 80% capacity of a slightly larger, but cheaper, battery? Really, until they deliver on their initial promise of “a fraction of the cost of lithium”, I think they’re on a hiding to nothing. It looks to me like they don’t have a believable path to achieving that goal.
