1. Problem: Lack of clean fresh water

2. Solution: atmospheric moisture extraction by a fully autonomous unit, without the need to desalinate the produced water. No chemicals, no electricity or other external power supply

3. Positive change of people's lives: access to clean fresh water; recovery of arid, solty or polluted lands; creation of water ponds, watering places for cattle or desert oasises 

SHORTAGE OR LACK OF POTABLE WATER. More than 40% of the world's population (about 2.5 billion) live in areas experiencing moderate or severe water shortages. This figure is expected to grow by 2025 up to 5.5 billion and make up two-thirds of the world's population.

ARIDIZATION.  Deserts spreading over about 1 billion hectares in the world.

DEPLETION OF UNDERGROUND WATERS. The world's groundwaters are more than 40% depleted

POLLUTION OF SURFACE WATERS. The total mass of hydrosphere pollutants is about 15 billion tons per year.

DEGRADATION OF AGRICULTURAL LANDS. In the known history of the mankind about 2.0 billion hectares of fertile land have been lost to degradation.

In Russia our technology is involved in the state programs aimed at providing fresh water for people living on arid, salinated or contaminated lands 

PRODUCTS AND SERVICES

- Production of clean fresh water 

- Recovery of agricultural lands

- Creation of water ponds or desert oasises

PROCESS AND TECHNOLOGY

- Extraction of moisture from the atmospheric air  with the help of a fully autonomous device. No need to desalinate the produced water. No chemicals, no electricity or other external power supply are required. 

- In experiment, at +16 degrees C of surrounding air we were able to produce 2 big drops of water per second, which amounts to over 80 liters in 24 hours.  But the most efficient operation starts at temperatures over 25 degrees C. Hot air is sucked into the unit thanks to a self-induced mini-tornado created inside by the special topology of the inner surface.  Inside the upper part (the hot section) the flow gains more velocity and becomes turbulent. At the dew point the hot air hits the condenser, which is permanently cooled by thermosyphons delivering low temperature from the deeper underlying soil.

With the existing test unit (D = 1.20 m), in some operational modes the production rate reached almost 600 l in 24 hours (in summer 2018). The team continues the trials to repeat the earlier achieved best results  

AQVENTUS is a self-running and stand-alone machine finally resolving the issue of getting water from atmosphere via employing vortex processes. Even with almost zero-wind outside, the vortex tech allows to accelerate the outcoming air to about 8m/sec. AQVENTUS has no moving parts (neither motors, nor gears or moving elements), which makes it almost maintenance-free. 

The ability to operate without power supply allows for installing the system off-grid, at a remote location in the desert, on the high seas or at a place hit by natural disaster. It also makes perfect base for an artificial oasis.  

The lower part of the unit (the cold section) is also an innovative solution. It resolves the long-standing problem of providing temperature gradient for moisture condensation without a powered cooling system. The combination of thermal syphons with capillary effect and the experimentally found proper angle of installation provide for uninterrupted delivery of cold from the deeper soils.

AQVENTUS is an omni-directional system, it doesn't depend on which way the wind is blowing at any given moment.  

AQVENTUS was developed from the very beginning to address the shortage of fresh or clean water 

Our goals for the next year are:

- to build a hybrid model of AQVENTUS able to operate either in power-free (off-grid) or in powered (on-grid) modes. A smart control system will switch the unit between the autonomous and powered modes, according to the current weather conditions

Our goals for the next five years are:

- to scale up the production and significantly drop down the cost of AQVENTUS, so that it could be installed in many areas in Bangladesh and other countries of the region

1) We need to conduct more research on vortex processes and flows. The better understanding of these phenomena will help create simpler and more reliable designs of atmospheric water extractors and many other industrial applications of this technology  

2) We need more research power, therefore international collaborators are welcomed

3) We need to run AQVENTUS in many different locations over the world to collect database on various climates and landscapes where access to clean water is an issue 

4) We need more money to support all the above activities and to launch mass production

1) & 2)    International and domestic collaborators are welcomed along with their research capacities

3) We suggest that governments or corporations should support building AQVENTUS in their respective countries. Our team in collaboration with   the national team of each country will carry out adaptive research and commisioning

4) We will participate in national and international calls for proposals and challenges; programs on clean water; programs on improvements of lands; programs on ecology and agriculture   

We plan to carry out adaptive research and then launch local production of AQVENTUS customized for the climate and landscape conditions of Bangladesh

Seven persons of fulltime staff

Our team developed this solution from zero-ground. It is the only team with proper knowledge and know-how of a fully autonomous, energy-free and maintenance-free atmospheric water extractor

Our partner and representative in Bangladesh is Arc Power Limited
