Putting aside the environmental benefits of having zero emissions or very close to it, as I said, the price today of the battery-electric is so significant, six to one. We're going to be making changes in the management of energy and the storage of electricity, as I was saying, by reusing batteries, doing stuff off peak hours, and storing it and using it.
I just think there will be so much more technology that's coming on energy optimization and management on electricity that I can't see the price going up to break even with the fuel prices.
