There’s been a lot of buzz lately about a box the size of a baseball that could power your entire house with fewer emissions than a modern power plant.

Bloom Energy has been teasing us with reports of a household fuel cell that’s a smaller version of the parking space-sized devices (pictured above) that are now being used to power the facilities of Google, Wal-Mart, FedEx and other big players.

It sounds promising, but some questions remain about the long-term feasibility of these fuel cell devices. Even so, I hope we hear more about this and other alternative energy innovations.
