Economies of scale.
Mr. Sanford, I have a question for you. Would it make sense for your company to approach the OEMs and discuss a package for the consumer that would include a natural-gas-powered vehicle and an installed home refuelling station, at an all-in-one price? Potentially, it would be financed over a defined period, and perhaps include the natural gas retailers in a fixed-price contract that would survive over the duration of the financing, so that the consumer could really price in the cost of a natural gas vehicle, the home refuelling station, and have a constant price over a five- or ten-year-period to show the financial benefit, guaranteed.
