Water from thin (but humid) air!

Sustainability problem

Water security (both quality and quantity)

The problem

Water is not only necessary to survive, but it is also a fundamental building block of a decent quality of life. Nevertheless, nearly 800 million people do not have water security (link).  Fresh water, which includes safe drinking water, account for less than 4% of all the water of the plant (link). Moreover, these water bodies are localized and accesses to them is limited. In short, there is an urgent need for potable water in many parts of the world. On the other hand, air is very abundant….

The solution – Water from air!

  • Water-Gen is a Israeli company that produces a line of Atmospheric Water Generators (AWGs) and de-humidifing products.
  • The units only require electricity to operate. The company’s largest generator can  produce up to 6,000 liters per day. Standard operating conditions are 26.7°C and 60% Relative Humidity.
  • The company claims its solutions are ideal for cities in developing countries and has identified 12 cities (ranging from Jakarta, Indonesia to Salvador, Brazil) that can greatly benefit from the technology, which can be integrated into existing buildings,
  • One of the nice features about the water generators is that their optimal operating period (when humidity peaks) is at night (when electricity demand is low).

Stakeholders

  • Individuals in developing countries with poor access to water
  • Individuals in developed countries who live in areas with contaminated water (e.g., Flint, Michigan)
  • Army and Science facilities that are “off the grid”.

Implementation

Step 1 – Partner with cities, organizations and countries that are in need for humanitarian aid  for pilot programs to increase public awareness.

Step 2 –  continue to improve the product and make it more “renewable energy friendly”, which will increase its attractiveness for communities with poor access to electricity.

Step 3- Expand operations and open additional factories that will allow the company to reach economies of scale, which will lower the product’s price.

Comment on A Bay Area Startup Spins Lab-Grown Silk (JANEVAMORFAW):

Thats is a very cool idea with great potential. I hope that the company will be able to cheaply produce enough “silk” and have a global presence so that they will be able to bring about a real change.

Two things stand out to me in this technology: 1) Is the farming of the planets the company extracts sugar from sustainable and are these plants widely available?  2) Can the company bring the technology to a sufficient scale so that it can “move the needle” and meaningfully make the apparel industry more sustainable?
