The sustainable technology slated for the build is very ambitious. According to the brief, up to 45,000 cubic meters (1,589,160 cubic ft) of rainwater would be collected annually in an area known for its aridity and used for various purposes. Most significantly, it would be injected roughly 4 km (2.4 miles) deep underground, at which point the earth's heat would turn the water into steam. This steam would then channeled to the surface and used to power a generator that produces electricity and heats water for the tower's heating systems. The same rainwater would also be used to irrigate the internal vertical garden and for toilet needs, with greywater recycled too.
