Latest XPRIZE contests focus on water production and women's safety
The XPRIZE nonprofit just announced its latest set of competitions aimed at "sparking breakthrough solutions to two urgent grand challenges." The first is the "water abundance XPRIZE," which focuses on harvesting clean water from the air using renewable resources. Specifically, the challenge asks participants to create a device that extracts a minimum of 2,000 liters of fresh water per day from the atmosphere, using 100 percent renewable energy. To make things even trickier, the cost can only be two cents per liter of water.
