With all the buzz around hybrids and hydrogen cars, it's easy to forget that the cleanest vehicle on the road is the natural-gas powered Honda Civic GX. While it might be clean, however, it is a pain to fill up thanks to its paltry 220-mile range and a scarcity of public natural gas fueling stations (fewer than 150 nationwide). To make life easier for GX owners, Honda has partnered with FuelMaker to develop the Phill home refueling station, which enables drivers to fill their tanks in their own garage. We got a close-up view of the first Phill system to be installed San Francisco. Check out the pics here.
