Say you have an electric eel laying around, what would you do with it? Well, an aquarium in Japan had a bright idea: use it to power the LED lights on their Christmas tree!
Each time the eel moves, two aluminum panels gather enough electricity to light up the 2-meter (6 ft 6 in) tall tree, decked out in white, in glowing intermittent flashes.

This reminds me: LED lights are finally coming into their own, and this holiday season LED light strings are popping up everywhere, from home stores to drug stores. At an average of 3 watts per string, they can bring all the holiday cheer for a whole lot less holiday cash! Plus, they burn cool, so they pose less fire risk than traditional bulbs.
You can contribute to a cooler planet this year by replacing your old Christmas lights with LED lights.
