Desert Tech

It's hot, dry, deadly, and hard to ignore with close to 40% of Earth classified as desert. But in this scorching hour, the desert turns from barren wasteland into an environment rich with hope. In the Middle East, desalination of seawater now fills water needs. Americans have created booming desert communities like Las Vegas, where the Hoover Dam produces hydroelectric power and manmade Lake Mead supplies water. Native Americans farmed the desert on a small scale, but 20th-century technology begot greater opportunity. Once desolate areas of California and Mexico now grow agriculture due to irrigation, and the desert's abundant sunshine allows solar-energy and wind-power production. And in the future, desert technology may enable colonization of planets like Mars. We also take a look at how refrigeration and air conditioning have made life in desert communities tolerable, and examine the latest in survival gear and equipment.
