Here's a unique way to power your Christmas tree. Connect the lights to a tank holding an electric eel.
The fishy tree can be found at the Enoshima Aquarium in Japan, where every time Mr. Eel starts to swim around, 800 watts of power starts to circulate through the tree's lights.
In the video, eel powered tree inventor Kazuhiko Minawa ponders about what would happen if you gathered all the electric eels on Earth, and connected them to one huge tree. That's just crazy talk man.
