Our technology
Zero carbon water anywhere anytime
Passive
ACWA captures water from air based on biomimetic design.
Zero carbon
ACWA does not need energy input from either the grid (dirty energy) or renewable energy.
24 hours a day
ACWA provides a delocalized water source from the air anytime of the day.
Large-scale applications
ACWA is designed for large-scale outdoor applications and can be applied on surfaces of any type.
How does ACWA compare to others?
Atmospheric water capture technologies available today require intensive energy input to harvest water from the air.
The most common method to extract water vapor from the air is to actively cool the air below its dew point. This process of changing the temperature of a space or surface is energy intensive. The bigger the surface area or space, the more energy is needed.
Extracting water vapor in the air through condensation, i.e., by cooling the air below its dew point is considered one of the most energy-hungry methods to harvest atmospheric water because intensive energy is needed to generate continuous cold. Think of the refrigerator in your home.
Research has shown that atmospheric water capture has no environmental advantages when it needs to be powered by conventionally generated electricity (e.g. coal-based electricity). [1]
