That's right. Actually, one thing that you have to consider is not to limit innovation, but there are some things that will have to be standardized at some point. René was using the example earlier that if you had a different nozzle to fuel your car today, it would make it very difficult to go across Canada with your car. You wouldn't be able to fuel. So at some point there are some things that will have to be standardized.
In other words, the plug technology—things like that—those things will have to be quickly standardized so that we can actually work on the more important stuff of how we can maximize the power density, how we can best use that technology, and so on.
