Awa Safe

A portable solar powered water collection reservoir that uses the Peltier effect and thermoelectric cooling to harvest atmospheric water.

What is it?

The Awa Safe is a portable solar powered water collection reservoir that uses the Peltier effect and thermoelectric cooling to harvest atmospheric water.

How is it used?

The Awa Safe is a simple, cost effective and portable system that can be comfortably worn around the body like a pouch or bag. Additionally, larger bags and reservoirs can be developed to increase water yield and supplies.

What technologies does it incorporate?

The Awa Safe assembly consists of a water reservoir, a solar powered fan and temperature sensor, heat and cold radiators, insulation, a rechargeable battery and a Peltier cell. The exterior body is made from a rugged, durable and hygienic silicone sleeve.

How does it work?

The Awa Safe system offers an easy method to harvest atmospheric water using thermoelectric cooling. Air with water content introduced into the system flows through a cold radiator. As the air moves into a heat radiator, the water in the air is extracted one drop at a time into a water reservoir. The air, now dry, exits the system from an exhaust vent. This cycle is repeated continuously.

Who uses it?

The Awa Safe is ideal for day to day use to supplement daily water intake. It is designed to be a fashionable and useful item that users will want to carry along with them. Fabric pouch sleeves can be designed by local artisans and reflect the local color and culture of the community.

In the case of emergency situations, the Awa Safe units can be easily deployed to communities in need. The Awa Safe will provide plentiful water for populations who are in the process of relocating to safer ground or to be attended to by emergency personnel and cannot afford stop to wait long lines or find sources of water.

Why does it help?

The search, collection and transport of water is a time consuming task that is hindering people from addressing other critical needs in their lives. The focus of the Awa Safe technology is to address the WASH needs of vulnerable communities with a device that can easily harvest atmospheric water.
