Remember how W said Americans were addicted to fossil fuels? Well, Joseph Aloisius Ratzinger (better known by his crew as '265-Cal') is addicted to renewable energy. First he had photovoltaic arrays installed on the roof of an auditorium in the Vatican. Then he had a solar cooling system built into the Vatican cafeteria. Now, the Pope wants his mobile bulletproof shell to be solar-powered. While we'd love to see some PV cells rocking out on the roof of the custom Benz, they probably wouldn't power a whole lot more than his DC Papal reading lights -- to that end, we're hoping he goes the practical route and installs a PV array on top of the Popegarage and simply juices the batteries between sessions of humbly waving to the teeming masses. Whatever he and his crack team of energy specialists figure out, we're sure you'll be able to read all about it in the next volume of The Energy of the Sun in the Vatican, a book that actually exists.
