The company, Bloom Energy, didn't offer many new details Wednesday about how it plans to make its promising fuel-cell technology affordable enough for regular people to buy for their homes.
That's an important question because the company's product - a box of fuel cells that looks like a giant filing cabinet - currently costs $700,000. Corporations are the first customers, but Bloom wants to cut the price to a few thousand dollars and put it in homes.
The CEO, K.R. Sridhar, said only that that could take a decade or more as the technology gets better and prices come down.
