Bloom Box could be the magical fuel cell that saves the world

Five to ten years from now, you could have a $3000 fuel cell power generator the size of a clock radio in your basement, turning natural gas into electrical power at twice the efficiency possible today. That’s the promise of the Bloom Box, a tiny power plant that combines oxygen and natural gas, biogas, or solar energy, and creates electricity.

This sounded awful fishy at first, until I read that companies like Google and Wal-Mart are supposedly already using such devices. Why haven’t I heard of this until now then? Still dubious…
