And this final note. Following up on Scott's piece about electricity, the Vatican is looking for a new Popemobile. Preferably one that runs on electricity.

Pope Benedict the 16th is big on clean energy, and the church even published a book showing what the Vatican has done to make itself sustainable. Apparently the main hurdle is the Pope's security force, which expressed concerns about the ability of an electric vehicle to act as a speedy getaway car in an emergency.

Not a problem, say the experts. Zero to 60 in three seconds flat. Mercedes makes the current edition of the Popemobile.
