I need an explanation with pictures for that, because it seems like the author is using ‘efficiency’ incorrectly.

This topic always reminds me of the opening scene[1] from Waterworld where a guy on a raft out in the sea passes his urine through some kind of filter that turns it into drinkable water, and drinks it.

I was a little kid when I watched it and wondered why he would drink his own urine when he was surrounded by such vast amounts of water. With this type of technology, maybe he wouldn't have had to do something so gross! XD

My guess is 385% better than the sun just shining on the water and and evaporating it out in the open
