One of the most valuable modern technologies is the atmospheric water generator (AWG). It pulls water straight out of the air around us. Several kinds have emerged, developed by different companies. Some were created in response to water scarcity problems worldwide, and others aimed at convenience while reducing plastic bottle use and carbon emissions. Some are large installations to supply communities or households, while others are small mobile units for off-grid nomads. But all of them efficiently pull water vapor out of the atmosphere and collect it as filtered drinking water.
Air-To-Water On The Go
Watergen, an Israeli AWG company, has been perfecting its air-to-water technology for decades. Its first products were large installations designed to supply businesses, towns, and residential buildings. However, its latest innovations are smaller and portable. The company shrunk its water-harvesting technology to be travel-sized for vehicles like trucks, RVs, and tiny home dwellers.
In 2019, it debuted an automotive AWG system for everyday cars that consisted of the generator outside connected to a tap inside located over the cupholders. It recently modified the mobile device to fit more oversized vehicles that spend long hours traveling because it makes more sense than a car doing short commutes. Off-grid explorers taking a road trip through places without much access to water, or truckers long-hauling cargo would benefit from a mobile air-to-water generator more than someone just going from work to home.
Watergen has named this versatile item the Mobile Box. It uses electricity from the vehicle (via a 12- or 220-V outlet) to pull moisture out of the sky by sucking in air through a fan. First, the air goes through a filtration system, then a patented heat exchanger that extracts the water through condensation, which is then processed through a multi-level UV light filtration system. Finally, the purified water ends in a reservoir that’s linked to a tap. Users can also remove the reservoir to empty the water into another storage container to free up space for more freshwater production.
Aerogel – No Electricity Required
Water vapor is always around us in the air, even in dry conditions. But what if you don’t have electricity to run a generator? Scientists from the National University of Singapore developed a ‘smart’ spongey aerogel that turns airborne water molecules into a drinkable liquid without needing an external power source or moving parts.
Prof. Ho Ghim Wei, who led the research team, said:
Given that atmospheric water is continuously…
