The excercise itself is way to long to be written down considering there's both code and regular text. With that said if anyone owns the book it would be greatly appreciate if you could help me with this excercise.
More specifically i do not understand how the powerUse() method functions.
I also don't understand the sentence about the ratio of retention to radiator bots (4:3) and how that in any way relates to the code(as i do not see any code about radiator bots, only retention bots).
Big Love! <3
