It's fairly similar.
We've really seen a spike in CNG sales. One of them is disproportionate, because we just happened to have a big customer in New York who bought a lot. I'm not sure that's necessarily indicative of a market trend, but definitely we're seeing a lot more major U.S. cities purchase CNG.
I think it's just frankly the cost of CNG right now. It's so much cheaper. It's in abundance. So they're willing to pony up and put the infrastructure in place, but it's.... We have had a noticeable increase in CNG.
My comments on the electric bus are really very similar. I think we want to remain, as a bus provider, sort of battery-agnostic and somewhat charger-agnostic. We believe there will be different types of suppliers of batteries that we want to make sure will work on our buses, and different types of charging systems.
Again, take the last three customers we talked to. We had one customer who said, “I want lots of batteries on my bus so I can go all day.” We had another customer who said, “Hey, I'm at an airport; I want very little batteries, because I can do induction charging and give it spot charges throughout the whole day. It's only going to go around terminals and rental cars.” We had another customer who said, “You know what? If you can recharge twice on a route for five minutes and get yourself two hours' worth of operations, I'm happy with that.”
We would want to be flexible to all of those needs.
