Bloom Energy Server - Wikipedia, l'encyclopédie libre. The Bloom Energy Server (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[1] produced from biological sources) to generate electricity on the site where it will be used.[2][3] It can withstand temperatures of up to 1,800 °F (980 °C), that would cause many other fuel cells to break down or require maintenance.[4] According to the company, a single cell (one 100 mm × 100 mm metal alloy plate between two ceramic layers) generates 25 watts.[5] Bloom stated that two hundred servers have been deployed in California for corporations including eBay, Google, Yahoo, and Wal-Mart.[6] Technology[edit] To save money, the Bloom Energy Server uses inexpensive metal alloy plates for electric conductance between the two ceramic fast ion conductor plates.

Bloom Box - Les 50 meilleures inventions de 2010 - Heure. Inventors have tried to use hydrogen fuel cells as a cleaner way to create commercial electricity, but they've always been limited by the cost.
That's beginning to change, however, thanks to a California start-up called Bloom Energy. Its Bloom Box — about half the size of a shipping container — generates electricity using solid oxide fuel cells, which provide juice by oxidizing a fuel source. In the case of the Bloom Box, that fuel source is natural gas, though the company hopes to substitute cleaner sources in the future. Silicon Valley companies like Google and eBay are already using Bloom Boxes for greener backup power, at a cost of about $800,000 each.

K. R. Was the Hype Around Bloom Energy Two Years Ago Justified? About two years ago Bloom Energy revealed its top secret “Bloom Box” fuel cell system and immediately created an incredible buzz.
It was amazing to see how much hype buzzed around what the company described as “a new class of distributed power generator, producing clean, reliable, affordable electricity at the customer site.” For a while, it seemed that there was nothing more exciting than Bloom’s fuel cells that promised to change the world someday. So what happened with Bloom Energy since then? Was the hype justified?
The good news is that unlike other cleantech super-hyped companies that captured the imagination in 2010 (i.e. Focusing on data center security – Bloom had a very impressive list of customers in 2010 including eBay, Wal-Mart, FedEx, Staples, and Google, which was one of the reasons the company was receiving so much attention in the first place. Oxide Fuel Cells solides et la boîte Bloom. Navid Chowdhury December 7, 2011 Submitted as coursework for PH240, Stanford University, Fall 2011 Introductions Distributed Generation (DG) is the idea of generating power on site at the point of consumption (rather than at a central power grid) and it is becoming more and more essential at both commercial and household level.
It allows its user the flexibility and control that commercial power grid does not. But more than that, it is the high efficiency and low transmission cost (and loss) that's beginning to drive its cause. SOFC works the same way as most fuel cells do but instead of a solvent electrolyte it uses a solid electrolyte. At the cathode, oxygen from the air is split into oxygen ions and free electrons. SOFC's are usually stacked together in series to generate power in quantities useful households and commercial institutions. Bloom Box: Qu'est-ce que c'est et comment ça marche?

Car Carrier's Powerplant Like a Bloom Box On a Boat. A Swedish car carrier now sailing from Germany to the United States is the world’s first ship with auxiliary power provided by a fuel cell. While fuel cells can’t propel ships — yet — Wallenius Lines’ M/V Undine features a 20 kilowatt methanol-fueled Wärtsilä WFC20 solid oxide fuel cell auxiliary power unit. The unit provides power when the ship is in port, eliminating the need for batteries and generators to run onboard navigation equipment, radios and creature comforts. If the solid oxide fuel cell sounds familiar, perhaps that’s because its the power source behind the much-hyped Bloom Box. Like the Bloom Box, the Wärtsilä SOFC operates at temperatures exceeding 1,100 degrees Fahrenheit. Also like the Bloom Box, the unit on the Undine didn’t come cheap: the EU contributed about $1.25 million to the consortium of researchers and maritime magnates known as METHAPU that created the ship’s high-tech, low-emissions auxiliary power unit.
