Yes I know they have been working with Corvus energy for the hybrid truck but that doesn't mean they can't change suppliers. Whatever applications they are using electrovaya for someone else was supplying them before, they have made a change. They may stay with corvus for the truck but I would question why they don't use corvus for the applications that electrovaya will be supplying if they are satisfied with them. Either way it is still nice to know they are working with walmart on several fronts.
