The world is at a cross roads. In a few years there will be a global water crisis and something needs to be done about it. There are millions of people looking at ways to make sure there is enough water for generations to come. This will be something that needs to be fixed.

Key Takeaways:

• It looks like a well, but instead of withdrawing groundwater, the WaterSeer uses the surrounding environment to extract water from the atmosphere.
• Lockheed Martin has developed and patented a Perforene graphene filter which it claims would reduce the energy cost of conventional reverse osmosis desalination by 20%, while withstanding higher pressure and temperatures.
• Fog catching could provide a sustainable supply of drinking water for small communities in water-scarce regions, but it is unlikely to generate enough water to significantly increase water supplies.

“If we take sub-Saharan Africa as an example, groundwater tends to be available in most places we work – about 20m below the surface. So it’s a management or infrastructure problem that prevents people accessing water, not a lack of it. It’s not really about fixing the problem with technology; it’s about fixing the system.”
