I am currently conducting various experiments to reduce the heat in my non-airconditioned workplace.

My previous experiment consisted of switching off nine of the eighteen computers in the reference library (which is pretty deserted during vacation time anyway) and putting up signs asking the readers to not switch them on unless all the remaining computers are occupied. A few hours later, temperatures did indeed seem to be somewhat lower than usual.

Currently, I am trying to figure out whether putting large amounts of tinfoil on my office window merely makes the office darker, or if it also keeps out the heat a bit. So far I can confirm that the room is definitely darker, but I'm not sure if it has become any cooler.

I've never had the opportunity to try this, but apparently if you have a fan, then get a bowl of water and a tea towel (or other fabric), and position them so that the tea towel is wet and is hung with its bottom in the water, and the fan is blowing across it. The tea towel is supposed to act like a wick sucking up the water, and the air crossing it evaporates that water, which removes energy from the air, cooling it.

I've never seen if this works, but if things are uncomfortable you can always try it. If it doesn't work, then just sit with your feet on the damp tea towel - we can lose a lot of heat from our feet, so long as there's something to conduct it away.

Failing that, sit with the damp tea towel on your head, but that might look silly.

Or you could just have faith in Viennese summers. They never last more than one week in a row. ;-)

In Buffalo,NY, known for its cold wet weather, heavy snowfalls, etc., they used to say, "Let's hope summer comes on a Sunday this year so we can have a picnic!"

@Jann. We used to make similar jokes in the past. A few years ago, for example, I read in the paper that summer was officially identified to have taken place on a Sunday in August between two and four pm. in the park of Schoenbrunn castle - and I was there!

This year, however, we have already had over a week with around 37 degrees Celsius (100 degrees Fahrenheit). Jokes about the weather have diminished lately.

Today, however, we witness the start of a predicted two days break in summer. Jumps of more than ten degrees (Celsius) up and down from one day to the next are also quite funny...
