'Bloom Box' Fuel Cell Offers Power for Your Entire House
According to Engadget, K.R. Sridhar, founder of Bloom Energy, unveiled his "Bloom Box" on Sunday's episode of '60 Minutes' (video from the show after the break). With two small blocks, each of which can fit in your hand, you could power an entire American house. The box is a fuel cell that combines oxygen and an energy source (like natural gas or solar rays) to produce clean energy through a chemical reaction. Within the box, there are three thin plates stacked on top of each other, covered with a special "ink" and separated by a cheap metal alloy. Oxygen enters one plate, while the fuel enters another. The two elements meet in the middle plate, creating a chemical reaction that produces electricity.
