Silicon Valley based clean energy start-up Bloom Energy will leave their stealth mode at 10am pacific today. Bloom Energy made a major splash over the weekend in CBS's 60 minutes. The fuel cell powered Bloom boxes are hailed to revolutionize clean energy.
The Bloom Box is supposed to become cheap enough to be placed in your back yard to power your home. Bloom Boxes are selling right now for around $700,000. Bloom Energy already has high profile customers including Google, eBay and Fedex that can afford them with some serious subsidies from the state of California.
The Bloom boxes produce electricity from bio gas, fossil gas or other fuels via a solid oxide fuel cell. The technology works, but the major challenge is to reduce the price to make the Bloom box affordable for home owners. Forbes has an interesting article on the challenges of the Bloom Energy technology. Hopefully, later today we will be surprised by how far Bloom Energy has developed to Bloom Box. The Bloom Box is not entirely clean as it still produces CO2. It is also not known yet how efficient it really is.
