Chile's Atacama Desert is as eerily beautiful as it is barren, hot, and dry. Yet this seemingly inhospitable patch of Earth might be the perfect host for a different kind of solar energy, one that has nothing to do with photovoltaic panels.

Solar updraft technology is attracting interest in desert regions worldwide in Chile, the Southwest United States, Australia, China, and the Middle East. Fueled by hot air, rather than direct sunlight, solar chimneys present a compelling prospect for producing clean, renewable energy. They also offer significant advantages over conventional photovoltaic (PV) panels—but at the moment, they face even more significant financing hurdles.
