steve mueller, the ceo of southwestern energy which produces 4% of the gas in the united states. pleasure to have you with us. >> it's great to be here. >> how many stations are there right now and what do you see as the potential there for opening more stations? >> well, we are part of three stations in arkansas. and there are 950 stations. only 400 are open to the public. >> only 400 are open to the public. i'm curious because as gm, most of these are going to be fleet vehicles. they have predictable routes. they know where they're going to be and they're able to fuel. what's it take to get a vehicle maker or get the consumer -- i mean, it's like the chicken or the egg. if there's demand there, people will buy the cars. but if they won't, the filling stations are there. what will it take? >> i think it's going to be a combination of several things. we're taking a leap that we're giving away cars to some employees so they can determine how it works. the other part, we've done a study and for about $18 billion which is not that huge of a number, you can put enough cng stations in
