Usage is not waste. Simply because you don't agree with his usage of a tub of water to cool his room doesn't make it waste. He chooses on what to spend his money. As for the ad-hominem attack on my handle, I'll simply say it's unwarranted.
is it not a waste for someone to open a fire-hydrant so they can bathe their dog's paws? Your definition of "usage is not a waste" is really questionable.
BTW, there was no ad-hom attack on your handle, but rather an observation of your potential leaning -- i'm a capitalist too ( i think most HN'ers are) so I figured i'd respond to make sure you weren't going to write me off as a hippy-enviro.
