What I want to express here is that I think there are still lots of places for batteries to be used sensibly in vehicles. It's mainly in the hybrid area. In the electric vehicles right now, batteries can be used, of course, but there needs to be additional development in order to be broadly applied.
For example, for a hybrid vehicle, the payback on your capital investment, which is your battery and other electric attributes of the vehicles, is only about four years as a consumer, which is pretty reasonable. That uses battery technology. Batteries can be applied to automotives sensibly, with a good payback, with today's technology.
With electric cars it can be applied, but only on a smaller basis until we get the battery technology ahead. The outlook for that, in my opinion, is uncertain. There's an awful lot of research going on. It could be soon. It could be a long way off. The answer is, I don't know, and I've spoken to a lot of people. I don't know.
