Details of Bloom Energy (Bloom Box), YouTube Videos of K R Sridhar

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 uses liquid or gaseous hydrocarbons (such as gasoline, diesel or propane produced from fossil or bio sources) to generate electricity on the site where it will be used; Bloom Energy representatives assert that it is at least as efficient as a traditional large-scale coal power station. According to the company, a single cell (one 100 × 100 mm metal alloy plate between two ceramic layers) generates 25 watts.

The Bloom Energy Server uses thin white ceramic plates (100 × 100 mm) which are claimed to be made from "beach sand" but are, according to Bloom's patent description, scandia stabilized zirconia (ScSZ), a well-known solid oxide fuel cell electrolyte material. Each ceramic plate is coated with a green nickel oxide-based ink on one side (anode) and another black (probably Lanthanum strontium manganite) ink on the other side (cathode), which are the most common solid oxide fuel cell electrode materials that have been developed since 1973.
According to the San Jose Mercury News, "Bloom's secret technology apparently lies in the proprietary green ink that acts as the anode and the black ink that acts as the cathode--" but in fact these materials are widely known in the field of solid oxide fuel cells (SOFCs). Wired reports that the secret ingredient may be yttria-stabilized zirconia based upon a 2006 patent filing (7,572,530) that was granted to Bloom in 2009; but this material is also one of the most common electrolyte materials in the field.

The company, started in 2002 by CEO K.R. Sridhar, is one of 26 named a 2010 Tech Pioneer by the World Economic Forum.
