Its previous work has focused heavily on large installations to supply communities, businesses and households, and its latest innovations shrink the water-harvesting tech into a form portable enough for overlanders, RVers, tiny home dwellers and other off-grid explorers.

The last time we ran into Watergen's work was at CES 2019, where it showed the Automotive AWG system. The center-console-integrated system was one of the wondrous highlights of the show, but it seemed an odd, limited use for a technology with such potential, a strange detour on a larger journey. Does the average passenger car driver really need a water tap over the cupholders?

If a mobile air-to-water generator is to find a following amongst drivers, it would be a far better fit for vehicles that spend long hours traveling through places without much access to water – motorhomes and camping trailers, specialized remote-work trucks and vans, and perhaps long-haul tractor-trailers, to name a few examples.

Watergen has made a clear move in that direction with the new mobility lineup it showcased earlier this week at Israel's Smart Mobility Initiative. The most versatile member of the Watergen mobility family is the simply named Mobile Box. It looks something like a traditional portable generator, only instead of burning fuel to create electricity, it uses electricity to pull water from the air around it.
