As climate change and the needs of 7 billion humans increase demands on the global water supply, the pressure is on to come up with ways to squeeze water from a stoneā€”or at least from the air. The Airdrop is a new gadget that steps up to the challenge by helping farmers in severely dry regions source water for irrigation systems by harvesting moisture that's evaporated into the ether. Edward Linnacre, the engineering student behind the project, won this year's James Dyson Award for creativity in engineering design for his low-tech solution to a grave problem.
