The up-to-now secretive startup Bloom Energy took the wraps off its technology this week, unveiling a fuel-cell system that the company claims can run on a variety of fuels and pay for itself in three to five years via lower energy bills.

The company's founder and CEO, KR Sridhar, said at the official unveiling of the company on Wednesday that the technology--when it's powered by natural gas--can cut carbon dioxide emissions in half compared to the emissions produced conventional power sources, on average. Several major companies, including Google, eBay, and Walmart, have already bought Bloom's technology, and in the few months these fuel cells have been in operation, they've generated 11 million kilowatt hours of electricity (about enough to power 1,000 homes for a year).

This is marvelous 21st century technology.  What else can one say?  To read the rest of the article, click here.
