[R]eel Xmas Green

KAKAMIGAHARA, Gifu -- An aquarium filled with exotic fish here is using an electric eel to power lights on a Christmas tree.

Each time the electric eel at the Aqua Toto Gifu aquarium touches a copper wire in its tank, it sends power that lights up globes decking a Christmas tree.

Officials expect the "eel Christmas tree" to be a popular attraction for dating couples in the lead-up to Christmas Day, when the tree will be removed.

After all the hoopla of that Bali Conference, this green technology might actually catch on ... until the eels find out what they're up against, of course.
