Google's piling on the superlatives, enhancing their giant web empire with a giant solar array -- the largest corporate system in the world -- on the roof of their million-square-foot Mountain View headquarters. The installation, according the Reuters, will be able to generate 1.6 megawatts of electricity, which is enough to power 1,000 homes or 1/3 of their on-site offices. Can't wait to hear the reports on how much money they save on energy bills in the first year.
