> consumer battery tech Depends which consumers you're talking about. There are huge, untapped markets in Africa and Asia where people have no refrigeration or washing machines (partly due to having an insufficient electrical grid, or a complete lack of one), and they would benefit immensely from being able to store cheaply generated solar power. A large enough battery system based on this tech might be out of reach for a single individual in those circumstances, but not for a group who pooled their money and shared it.
