"A space-age structure that could be the greenest office building of all time." "A living building that has no carbon footprint." That's the spin. So is this: Google spokespeople are telling reporters that plans are on hold. Charleston East, site of Google's planned superplex, used to be a parking lot for Mountain View's Shoreline Amphitheater, just up the road from Google's main campus Now the lot is idle, pending a bunch of paperwork by the city. But here's the truth: The building was planned when Google was growing by more than 100 employees per week worldwide. Last quarter, it added 500 Googlers to its ranks — about 40 a week. That's why Google has shuttered a café. There's green, and then there's green. Eric Schmidt, America's CTO, is not thinking about the tree-hugging kind right now.
