Greenpeace demands a cleaner iCloud at Apple's corporate campus.

Since April, the environmental organization Greenpeace has had a bull’s-eye on Apple in its campaign to clean up the Internet “Cloud” that stores our music, apps, and photos. It’s accused Apple of using high-carbon “dirty fuels” like coal to power its new data center in North Carolina and has used dramatic pranks and slick videos to get consumers involved.

Sunnyvale-based Bloom Energy made a big splash in 2010 when it came out of stealth mode – on the CBS program 60 Minutes no less – and announced its high-efficiency fuel cell, spawned by a NASA project for Mars. It has earned an impressive roster of clients including Google, eBay and Walmart.

But beyond the inevitable skeptics, the really big catch? “Bloom Boxes,” as the fuel cells have been dubbed, have a price tag of around $700,000. Hardly affordable for all but the largest companies with plenty of cash.

Yet California Institute of Technology, the private research university generally known as Caltech, had twenty Bloom Boxes installed on its Pasadena campus in 2010. Each box now produces 100 kilowatts of electricity for a total of two megawatts capacity; or 17% of the university’s electricity demand.
