The Rising Influence of Rising Affluence

It would be difficult (although not impossible) to distinguish between the uses of the cng derived from the home natural gas line.

In the video you cited in #msg-47810055, the customer has two NG meters sitting side by side—one for the house and one for the car. The announcer states that the two NG lines are billed at different rates; I presume this means that the car rate is higher in AZ, where the Phill owner in the video resides.
