The $30, gravity-powered air conditioner

In New York right now, it’s insanely hot, so I’ve been out shopping for air conditioners. I was thus tickled to read about the ultimate low-tech cooling unit, created by a Canadian engineering student who was too broke to pay for an A/C. For $30, he wrapped a regular fan with copper tubing, then filled a garbage can with water and ice. He pumped the water through the tubing, using gravity as a free source of energy. Presto — it cooled the room for up to three hours per filling, as he describes on his site:

If you look closely, you can see the condensation from the incoming icewater, but no condensation on the tubing leading out. This is perfect, as it means that heat is being transferred from the room to the water.

I love low-fi hacks like this.!

(Thanks to Boing Boing for this one!)

My Xbox broke, and I was trying to Google some possible technical solutions, when I noticed that Google appears to be encouraging me to make a typo. I suppose it’s possible that Google’s algorithms know that typing “wont” instead of “won’t” would produce better results.

On the other hand, when I tried the test for multitasking, I was pretty abysmal. I performed worse than people who identify themselves as heavy multitaskers, and those who identify as low multitaskers.

I finally got around to trying out the interactive “test your distractability and multitasking” page at the New York Times, which they put up alongside their story earlier this month about how computer distractions are eroding our lives. 

According to the test, I guess I have good focus — I’m not very distractable!
