Everyone has likely seen this already but I can simply not avoid posting it, via boingboing, a Japanese Christmas tree is powered by an electric eel. After viewing this I can't look at anything without imagining it powered by electric eels. The electric toothbrush notion is a little icky but can't you imagine a treadle attached to the eel tank which would agitate it when you needed more power?
Is it me, or is there something more than vaguely sinister about his conjecture regarding harnessing the power of all the electric eels in the world? I'm thinking we have a glimpse at a neophyte James Bond villain here.
