Homebrew Air Conditioning for Under $25
inkey string writes "Summer has arrived, and I've been busy slowly overheating in my student house without central air.
I decided to put my thermodynamics classes to work however, and produced this ~24$ homebrew air conditioner. It'll cool a room to a comfortable level in 15-20 mins, and will run for a few hours on a garbage pail full of water.
It's cheap, environmentally friendly (just fire the waste water off to your garden), and makes a good one hour project for a quiet evening."
I hope his server isn't in his room, because all the thermodynamics courses in the world wont teach you about slashdotting.
...right next to your webserver.

Today it hit 70F, and the news stations are talking about "the heatwave of 2005".
sorry...
Dude, you're in Canada. Open the window.
Now you just have to figure out how to keep the snow off of the carpet.
I think that his garbage can full of ice water should at least have a few cold beers. I mean really, he's in college!
Wait... this retard thinks that using his fridge, inside his house, to produce ice... then cooling with the ice... is going to make his house cooler? He could accomplish the exact same thing by just opening his freezer door, right? I hope this kid's Thermo professor sees this and kicks him out of school.
If he's into thermodynamics he should realize the reason this is appearing to be a cheap way to AC is he's ignoring the need for the supply of cold water. (ice) Wouldn't he cut out the middleman here (and thus, theoretically increase efficiency of the system) by simply leaving his freezer door open with a fan in front of it?
I suppose it might still work running on cold tap-water, but then that could make for an expensive water bill. Although not nearly as much as running your freezer with its compressor all day long...

I don't know whats worse, the idiot parent poster who doesn't RTFA (or knows what he is talking about) or seemingly endless replies saying the same damned thing one after the other as if they were the first to point out the error and should get some sort of brownie points.
If he wants to be cheap, why not just take an old fridge ($20), remove the doors, and use the fridge to block the door to his room? Leave the coils facing out into the hallway, and his room becomes cooler - plus the light will always be on, so he can see wtf he's doing.
Ice Pixies magic it up, so he doesn't have to run a refridgerator/freezer to make the ice. Because, you know, those actually produce heat inside the house, which he is trying to get rid of... Pixies. Yeah, that's it.
Things can go horribly awry when putting AC units in...
Redneck Airconditioning!
Wait, but you haven't heard the best part--if you get some firewood, a match, and a fan, you too can have a really cheap heater for the winter weather!
First person to do it and put up a website about it will win the rights to a blurb on the front page of Slashdot!
Ottawa? Don't the OpenBSD folks hang out there occasionally? You might not have any penguins, but maybe there are some blowfish. :)
Yeah, but does it run Lennox?
I think my way is much more efficient and more environmentally friendly. I just hooked my freezer up to my perpetual motion machine and leave the door open. Infinite cold air, and no puddle of wasted ice water outside my window.
Isn't there some irony in that Waterloo has met its waterloo? No, I suppose its perfectly apt.
Perhaps you meant "I suggest that you start with capital letters" or "I suggest starting with capital letters"... It might be a good idea to choose a single qualifier, as well. Beginning one clause with "if" and the following with "perhaps" just doesn't read nicely.

Clumsy grammar is not terribly persuasive. Perhaps you can join him in his English studies - that'd likely help with the quality assurance needed for your technical writing.
