As the desert terrain is mostly flat in nature, it provides no shelter from the intense winds that scour the region. Madruejian engineers have created windmills to harness this power. Made from straw, wood and clay, these windmills turn as the wind blows through them, turning a central crankshaft and allowing the devices to mill grain and other agricultural goods. They vary in size and number.
Another device that harnesses the desert wind, windcatchers, or Badgir, vary in size and construction, as well as the way that they function. Nonetheless, they all operate in a relatively same manner: by redirecting hot air through them and cooling that air down as it flows out through another exit. They are essentially a form of air conditioning.
A Madruejian Icehouse, or Yakhchāl, actually allows Madruejian to enjoy ice cream and other cold treats right in the desert. A large dome is built over a cavernous underground facility where the ice is stored. The shape of the structure funnels any hot air right out of the top. Madreujian Ice Cream is well known throughout the country and indeed, the whole world.
Also known as the Ab Anbar, these structures work in a similar way to Madruejian Icehouses, having a structure on top covering an underground chamber where the water is stored at a cool temperature for later use. Pully and pump systems allows the water to be moved from the structure, so that it can do to where it is needed the most. Many have windcatchers built in to keep the water cool.
These canals, or Qanats, are dug underground to prevent the water from being evaporated by the intense desert sun. They run on a gravity principle, so no pumping systems are required, and use ground water as their source. The quality and quantity of the water thus varies from region to region.
