Apparently I'm technology impaired. It took me a an hour to figure this one out. The bellboy in my hotel (Montevideo, Uruguay) didn't give me the heads up. That's fine, I'm usually a pretty smart guy. Not today.

The light switches in the hotel don't work!

What's this salad?

ohhhh.... you put your room key in here and then all the light switches work. Nice.
Yeah, I totally want that for my apartment now. That's just too brilliant! It saves so much energy that the US will clearly never adopt such a thing.
