Bloom Box as Fuel Cell of the Future
Hydrogen fuel cells were once considered the cleanest possible way to create commercial electricity, but unfortunately, they yield limited application because of the cost.
Slowly, but surely, that's beginning to change thanks to a California start-up called Bloom Energy.
This company makes what's called the Bloom Box. At about half the size of a shipping container, it's pretty compact in relation to what it's capable of doing. These Boxes cost about $800,000 each.
It generates electricity by using solid oxide fuel cells. In short, electricity is harnessed by oxidizing the fuel source.
In the Bloom Box, the fuel source is natural gas. So yes, in order to get electricity, this technology will still have to depend on extracting natural gas from the earth, but the company has plans to substitute cleaner sources in the future.
Silicon Valley corporations such as Google and eBay already use Bloom Boxes for greener backup power.
