Well, we would say that it's low-cost to begin with.
I think the point I'm trying to make is that the Prius is seen is as an environmental step forward. Part of it is due to the technological achievements that the Prius engineers have been able to achieve. We think there are different ways to use wood, and if you take into account the life-cycle assessment of the making of the material and then of course the building itself that the materials are used for, we should be looking longer-term.
One of the challenges you have with the Prius is that, as I understand it, there are some high-end expenses put into it, but then also it becomes like a regular car at the end of the day, and maybe even more environmentally detrimental at the end of the day. We think using wood is a better way for the long-term horizon for the building structure.
