Fuel cells have long been a green dream for environmentally-minded techies: combustion-free power for homes and businesses.
Now K.R. Sridhar says his well-funded startup, Bloom Energy, has made it a reality.
The Bloom Box takes any number of fuel sources, like diesel, natural gas, or propane, and converts it to electricity through a chemical reaction. It can also store electricity produced by clean sources like solar or wind. But it's only as clean as its energy source.
Sridhar hopes to put a Bloom Box in homes, though the price will obviously have to come down by orders of magnitude. For now, energy-hungry businesses are its first customers.
eBay CEO John Donahoe says the company has saved $100,000 in electricity costs so far, and his company is hosting Bloom's public unveiling later this week.
