I get it.
I'm interested in this because I believe that it will be an attractive option for consumers, given the price disparity between natural gas and gasoline. There is the possibility now to fill up a car at night at home in your garage or your driveway and then drive at a significant discount to the cost of gasoline, except that every family wants to take a road trip at some point in time and there aren't enough natural gas stations to refuel with. Obviously they're not returning home to fill up, so do you see the technology moving in a way that will allow them to substitute gasoline on occasions when it's not possible to power up with natural gas?
