Well, this news should make T. Boone Pickens happy.

According to USA Today, if you're flying into Dallas/Fort Worth International airport, the taxi you hail could very likely run on compressed natural gas.

That's because the airport -- following the lead of San Francisco International, Boston Logan and San Jose Mineta -- now gives preference to compressed natural gas (CNG) vehicles, allowing them to cut to the front of the taxi line ahead of gasoline-powered taxis.

A group representing gasoline-powered taxi operators in Dallas has brought a lawsuit against the DFW airport as a result. The litigation is ongoing.

Ninety-four percent of airport vehicles at DFW, such as rental-car shuttles and parking-lot buses, already run on CNG (the airport has plans to build a second CNG fueling station to accommodate the fleet), but only 1 percent of taxis authorized to operate at the airport do. The new rules have been made in the hopes of causing more taxi operators to convert. In Boston, that same plan has had noticeable effects: Since the plan started in 2007, 340 of 1,830 cabs in the city have converted to alternative fuel.
