One of my readers sent me a note introducing Air2Water. He explained that it could be used to reduce the amount of vulnerable supply convoys in Afghanistan. In Afghanistan, convoys carrying fuel and water have been in most of the ambushes and IED attacks. Why? Because these resources truly keep our soldiers moving.

Air2Water (link) works well in humid environments. It sucks in the moist air, and filters out clean water. They even have examined solutions for the military (link).

Despite being extraordinarily unique and unheard of, I think the idea deserves to be considered. This idea sounds unpractical because of its uniqueness, but that doesn't mean we should discard it.
