I'm always amazed by technology that's inspired by nature.

Scientists are experimenting with a device made from carbon nanotubes that draw water from the air, even in very dry places. They were inspired by the Namib Desert beetle, which catches water from morning fog to survive in the desert. The device works well but it's too expensive to make on a large scale.

I think it's fascinating, but needs more work to be practical. I'll still be carrying a water bottle next time I visit a desert...
