A man drinks the water produced by ELU, a remote-controlled robot that can extract water from the air, invented by Mahmoud El-Komy, a 27-year-old Egyptian mechatronics engineer, in Borg Al Arab desert, Alexandria, Egypt September 1, 2021. El-Komy says the robot is able to condense moisture from humidity and would have the ability to work in environments that are more difficult than Earth's, such as during space flights or even on Mars.
