The Bloom Energy Server (commonly referred to as the Bloom Box) is a solid oxide fuel cell (SOFC) made by Bloom Energy, of Sunnyvale, California, that can use a wide variety of inputs (including liquid or gaseous hydrocarbons produced from bio sources) to generate electricity on the site where it will be used. It is highly efficient, low cost and has low polluting emissions. This type of fuel cell can withstand temperatures of up to 1800°F, which would cause many other types of fuel cells to break down or need maintenance, and is highly advantageous for its smooth operation. According to the company, a single cell (one 100 mm × 100 mm metal alloy plate between two ceramic layers) generates 25 watts. Bloom stated that two hundred servers have been deployed in California for a number of corporations like eBay, Google, Wal-Mart and many more.
