Holy bee looks heavenward for papal transport options

摘要

There's a higher power at work at Vatican City.No, not that one. It's solar power, and it could change the way the pope travels.Some background: In 2008 photovoltaic cells were installed on the roof of the Vatican's main auditorium. A year later a solar cooling unit for the main cafeteria was installed. And now Cardinal Giovanni Lajolo, who runs the Vatican City state, has said Pope Benedict would be up to using a solar-electric Popemobile rather than one powered by fossil fuels.
