How about in wet, hot environments (or even cold ones), like on a boat? Watermakers are very expensive and use a lot of electricity. If one could do this on a boat to generate clean drinking water, that would be pretty amazing. Especially if one could use a tube solar oven to heat up the substance.
> The research builds on previous breakthroughs from the team, including the ability to pull water out of the atmosphere[1] and the application of that technology to create self-watering soil[2]. However, these technologies were designed for relatively high-humidity environments.
