Oil and gas

As we continue to think about the Keystone Pipeline, there's a small article about a "major spill" from an existing pipeline in Arkansas. No one knows what caused it: these things happen, I guess.

A longer article in today's Washington Post talks about the billions and even trillions of dollars that it will cost to fix 495, the Washington Beltway. Worth reading.

Finally, another article from Bloomberg about injecting CO2 to extract more oil from old oilfields. Injecting CO2 is probably good for the climate, but burning oil obviously isn't. Sounds like environmentalists on balance are nonplussed.
