An over-analytical whiny rant about the Japanese Christmas eel tree

First off, I'm talking about this article.

Using an electric eel to light a Christmas tree, or provide any electricity at all, is not eco-friendly. The only reason it's even remotely efficient for the aquarium is because owning the eel has value to them outside of the fact that it's providing electricity.

The electricity generated by an eel is a predatory device it uses to stun prey it's going to eat. It is by no means a primary function of the eel, and the electricity it generates is secondary to more important forms of energy usage that keep it alive and moving. So besides electrical generation, the eel has to consume food to keep it alive, keep its cells functioning, and keep its nervous system working.

Eels are somewhat high on the food chain and eat fish for food. Those fish have to eat smaller fish and those have to eat smaller fish, and so on, all the way down the food chain. My point is that, as an electrical generator, an electric eel is incredibly inefficient compared to something more direct like burning oil or solar power or whatever. I know it was tongue-in-cheek, but if we had eel generators in our homes, we would have to expend tons of energy feeding the eels, probably orders of magnitude more than we could ever actually get from the them. Not to mention massive fish farms we'd have to use to feed them all.

This is the same problem as other so-called eco-friendly energy carriers that are frequently misidentified as sources. Hydrogen was apparently this miracle that was going to save us all, but like the eels, there's a lot more that goes into it than you'd ever get out. You have to use electricity to produce the hydrogen, then energy to transport and store it, and by the time it gets in your car the net energy output is far less than what went into getting it there in the first place.

I know I'm ranting about some dumb article about a goofy display that ultimately means nothing, and I'll probably get downvoted. But I'm tired of completely inefficient non-solutions to our energy problems being touted as "eco-friendly" when they are in fact the complete opposite.
