Bloom Energy has actually been operating for 8 years, raising $400 million in funding from VCs including Kleiner Perkins (investors in Netscape, Amazon, Google and others). Its “Bloom Box” houses fuel cells that run on oxygen plus natural gas, landfill gas, bio-gas or even solar.

The company’s first customer was Google, which has been powering a datacenter on 4 Bloom Boxes for 18 months. Google’s boxes run on natural gas. eBay is also a customer — the company has 5 Bloom Boxes in San Jose, which it says have saved $100,000 in energy costs over 9 months.
