Unintended air conditioned consequences

As the world gets warmer from global warming more people use air conditioning which increases Co2 emissions which increases the warmth of the world which causes more people to use AC... this positive feedback loop turns out to be non-trivial. Cooling a Warming Planet: A Global Air Conditioning Surge. Some facts about air conditioning and the environment, by Stan Cox. [more inside]

An affordable cool.

Keeping Cool at Lower Cost. A fine summary of the latest innovations in the technology of air conditioning. e.g. "If [fan] blades were designed for better aerodynamic efficiency, instead of being stamped from sheet metal as cheaply as possible, the electricity consumption of many cooling systems could be cut by a third.". Includes a look at how to cool a building using hot water in a device called a thermal cooler.

It’s uncool to stay cool?

Chill, Toronto

Cool! Toronto's Deep Lake Water Cooling System was launched today. The system cuts electricity consumption in commercial buildings by 75 per cent by drawing near-freezing water through pipes extending five kilometres out into Lake Ontario. According to the city, the system will save enough power to service more than 100 Toronto office towers or 4,200 homes per year, and it will eliminate 40,000 tonnes of carbon dioxide. Here's a public television segment explaining the process. Seems like it makes a nice complement to the lakeshore windmill.

The Cold War

Operation: Air Conditioner
It's about dropping our differences and getting together to support our troops and keep them cool.
Should I feel terribly guilty about giggling at some of the things on this web page? Like: "Together We Are: An Army of One" (Say what?) and "Here are some of the items that I buy and send besides air conditioners: Baby Wipes, Powder... Liquid Soap (I heard the bar melts)... Tiki Torches. Check out the Baghdad Weather Report near the bottom, and... wait a minute... "I’ve organized people to begin “Operation Christmas” and we need to start planning that in August." (So we aren't leaving anytime soon?)
And, while they seem to have enough power to run the A/C at the Army camp, electricity for the rest of Iraq is still gonna take some more money.

Badgirs--Windcatchers

Badgirs (Farsi) or barjeels (Arabic) are windcatchers that work as low-tech air conditioners. The city of Yazd, Iran is probably best known for them. Badgirs are built so that they can be opened to catch the wind from different directions, the air is then cooled as it travels down the tower, and in turn cools the rooms below. When there is no wind, air in the tower is heated and rises, which draws cooler air from the courtyard into the house. (There is no URL to link to for the search result for “badgir” on Encyclopaedia Iranica, but I recommend checking out their definition and diagrams even though you’ll have to go through three different PDF pages.) Badgirs have been around in some form “since the New Kingdom (1500- 300 BC) in Egypt”, but global warming might make them ineffective.(scroll down to #16-#18) Variations, such as malqafs, can be found from Egypt to Pakistan. You can get a modern one for your own house. You can win an award shaped like one for advancements in sustainable development. Or you could just stay in the Fairmont Dubai Hotel which is shaped like a huge badgir. So even after all this, I still don't know what those sticks sticking out of the sides are for.

Happy 100th Birthday

Happy 100th Birthday to one of the most important inventions of the 20th century, not to mention the coolest. I would bet that most people that are reading this right now, at least in the US and other parts of the Northern Hemisphere, are benefiting from this invention, originally designed to take the curl out of paper. It also made summer blockbusters like Mr. Deeds bearable. (I guess every good thing has some downside.)
