Atmospheric water harvesting

Latest research is to replace zirconium with aluminium. 
https://www.kqed.org/science/1924858/new-device-produces-water-from-thin-air-no-electricity-required MIT invention with Zirconium , uses no electricity.Yaghi: To get the water out, as the goal is liquid water, one simply needs to heat the materials to a mere 45C (113F). This is the temperature [needed] inside the enclosed device, which can be a lot higher than the ambient outdoor temperature – similar to the greenhouse effect. This provides enough energy to break those weak bonds and release the water from the pores. This was very surprising, but also exciting. It meant that certain MOFs can be used to trap water from the atmosphere especially in arid climates, and then be released easily for collection.Metal-organic frameworks are materials made by stitching together organic and inorganic units into porous frameworks, which can have extremely high internal surface areas. One gram of a MOF the size of a sugar cube has an internal surface area equivalent to an entire football field.This high surface area ensures high capacity for the captured water. The ability to modify the pores chemically by changing the chemical characteristics, and physically by changing the pore size and shape, leads to MOFs tailored for specific functions such as water capture, carbon dioxide capture and conversion to fuels, methane storage for automobile fuel tanks and so on.
We are currently working on the next generation MOF water-harvester. I think after further improvement, a MOF water harvester the size of a washing machine could satisfy the most basic needs of a household. Metal Organic

http://www.eolewater.com/ Eole Water is the pioneer in the field of water making systems using air as a source of water. The company has invented in particular the first wind turbine able to create drinking water from condensed air.
https://www.youtube.com/watch?v=ZYaPxbNoO_U The SYSTEM OF ATMOSPHERIC HUMIDITY CONDENSATION, registered under Patent number INPI 200100101562, was conceived with the humanitarian aim to provide drinking water to communities that lack the same, wherever is need it and it is available to any public or private entity willing to develop it.

https://www.youtube.com/watch?v=yL3Ps86N2nM coloBlue's new 400,000 Liter/Day Atmospheric Water Generator Station. We present the 3D design concept video of the project. Not only can EcoloBlue's atmospheric water generators be used individually for smaller water needs, these water stations are intended for areas where the need for water is greater. Please contact us if you wish to discuss a possible project. This is just showing an example of how the machines can be bundled together to create more water than a single machine. Focusing on the palm trees, fountains, third party energy sources, etc are not the focus of the EcoloBlue Technology. They are all secondary and imaginative just to get the point across.

The Groasis Ecological Water Saving Technology helps to plant trees and vegetables with 99% less water use Visit http://groasis.com for more information. This is a video of a series of videos that show our research to find a way to produce vegetables with less than 70% of the normal water use. These is the first experiment that we have done. It is done in Holland.

The average water harvesting rate varied in a range of 0.05 L/h for cold and humid to 0.65 L/h for warm and humid climates. The average energy consumption changed from 1.02 kWh/L for warm and humid to 6.23 kWh/L for cold and humid climates.
https://www.youtube.com/watch?v=C1G2oC2cuTw n this video we are going to look at Atmospheric Water Generators. In the last decade, there has been a lot of development for creating efficient machines that can extract water from the air. 
Their are four different technologies being used. They are refrigerant based AWG, Desiccation based AWG, Peltier (thermo electric generator) based AWG and hydrophilic surface based AWG.
At present the company called Watergen has been able to produce a litre for just 300 Wh of energy.
