For as long as there have been people living in hot climates, they have come up with ingenious ways to cool themselves and their homes. The idea of air conditioning dates back as far as the ancient Egyptians. In the desert climate, they hung wet reeds from their windows, and the breeze would blow the cooler and more humid air into the homes. In the second century, a Chinese inventor created a rotary system to turn wooden blades, creating a fan. The Romans used sophisticated piping running through the houses of prominent people to keep them cool. All of these techniques are still at play in one form or another in modern air conditioning units. The process has been much refined and controlled, but still occasionally runs into problems.
