The definition of a "meme" here is intentionally pretty loose. Images, screenshots, and the like are welcome!
But, keep it lighthearted and/or within our server's ideals.

Electrolysis of the most expensive process (PEM) is around 80% efficient by itself. The more common methods are 70%. Anything that uses it after that only drops it further. Fuel cells max out at 60%, which means that electrolysis to electrical output efficiently is about 50% altogether in the very best case.
Some of the better internal combustion engines are reaching about the same.
