For the CNG infastructure issue, it's much more in place than you might think.

I had the pleasure of sitting next to the CEO of Laclede Gas when I was catching a ride back to STL from ORD one day. While stuck on a ground stop at 5pm, we struck up a conversation. This was when oil was around $125/bbl.

I asked him why they weren't persuing this more. In the St. Louis area, 75% of the homes are heated with natural gas, a large number of fleet operators use them (many in the public bus system, city and county public works, etc), the technology itself has been in use for about 15 years and most auto makers already produce CNG cars in small numbers.

His reply, "we've discussed it. However it's hard to lobby when you're going up against the oil companies. Also, people seem more willing to have to buy a charger for a car than a CNG outlet for their garage."

I didn't know that much about T. Boone Pickens, but something didn't sit well with me. Now that I know about his hedge fund it makes a little more sense.
