Bloom Energy are producing tiny fuel cell boxes they call “Bloom Boxes.” Two of these can apparently power a U.S. home (and only one for homes in countries that use less power). So how small are they? Look at the picture above, each device isn’t much bigger than a standard brick. Of course, they need to be surrounded by a larger unit that takes in an energy source (such as natural gas). But still, these units look to be about the size of a refrigerator and can easily fit outside of a home, providing it with clean, cheap energy.
Currently, these boxes cost some $700,000-$800,000, but eventually, founder K.R. Sridhar envisions one in every home — and he thinks he can get the cost below $3,000 for a unit to make that happen. And he’s talking a 5 to 10 year timeframe for this.
