Delivering a compact, lightweight and battery operated atmospheric water generator
This project aims at advancing the development of a compact and lightweight battery-operated unit for production of water (4 litres per day) from atmospheric moisture.
Operating based on the Peltier effect, the unit incorporates semiconductor-based heat sources/sinks and a microfluidic heat exchanger. The project focuses on optimising the current design by minimising the unit’s energy footprint, physical dimensions and heat/noise signatures while improving its ruggedness.
- Relying on ambient moisture as a source of water
- Ability to produce drinking water from air even at very low absolute humidity levels (typically at levels greater than 5 grams per meter cube), thereby, deployable almost anywhere around the globe (except Antarctica where the absolute humidity is zero)
- High efficiency (requires a 24 watt power source) and lightweight and compact
Successful applications of research
- Implementation of the project outcomes into the design of the future field equipment for Australian Defence Force (ADF) combat personnel, particularly, the Special Forces
- Australian National Fabrication Facility
- The technology under development in this project provides the ADF personnel with a simple device for producing clean water in the battlefield
- This should enhance the operational capabilities of the ADF's Special Forces which are often deployed as small teams to the field for extended period of time and lacking logistical support to replenish their drinking water supplies
